2 Preparing to Install Your Server Before you install the server in a rack, you should carefully consider the placement of the unit in its rack and several factors in the infrastructure that will keep the server operating efciently.

Guidelines for Server Installation

To ensure safe and smooth operation of your server, its essential that you plan for proper location of the server in its rack, adequate power to the components in the rack, and the appropriate operating environment for the rack.

As you plan for server installation, follow these guidelines to ensure that the server and its environment are safely and appropriately positioned for efcient operation and service.

Choose the Servers Position in a Rack

When determining the location for the server in a rack, be sure to allow adequate space for airow and servicing from both the front and back.

m Air to cool the server ows from front to back. Do not cover the front or back of the server or any of the openings in the servers front and back panels and case.

Do not block the air flowing through the server.

19

m The server slides out of the rack from the front. Be sure to leave a minimum of 36 inches clear in front of the server to allow room to open and service it.

m To provide access to the servers back panel and cables, leave at least 24 inches clear behind the server.

m If you are installing multiple servers or other components in the rack, place the server so that you can easily open and service it. For example, in a multiple-component installation, the heaviest itemssuch as an uninterruptible power supplyare usually placed at or near the bottom of a rack; servers are often located near the middle of the rack.

m For a rack with multiple components, you may want to prepare a list of all equipment in the rack and the requirements for each unit. Such a list should include the following information:

Electrical Power

If you plan to install the server in a rack that contains other components, be sure that the circuitry and power connections are sufcient for the combined power needs of all components. To plan for safe and adequate power to the server, follow these guidelines:

m Check the documentation for all components in the rack to determine their power requirements. Also determine that the available power supply for the rack is sufcient for the planned components.

m If you need assistance in determining the power needs of the components in the rack, consult an electrical expert who is familiar with your facility.

m Make sure that the power connections for the server and all other components are grounded (according to local and national standards). Consult an electrician if you need assistance with grounding.

m See Appendix A, Specications, for more information about electrical power requirements for the server.

Component 3

Important When planning for electrical power, make sure you have more power than specied for all components. Also make certain that the power load is distributed evenly among circuits to the racks location. Consult an electrician or other expert if you need assistance with planning for the power needs of your components.

20 Chapter 2

Operating Environment

The operating environment for the servers rack must meet certain requirements:

m Verify that the temperature range of the racks location is within the limits established for the server and all other components.

m Make certain that the racks location has adequate ventilation to maintain the necessary temperature range. This is particularly important for a rack that is enclosed in a cabinet.

m If multiple components are installed in the rack, consider additional cooling to assure efcient operation of the servers and other equipment.

Rack Stability

The rack must be stable and strong enough to hold the components installed.

m Check the documentation for the rack to make certain that it can carry the load of components.

m If you are using a two-post (telco) rack, verify that the rack is securely fastened to the buildings structure at the top and bottom.

m Make certain that all components are secured in the rack.

m When working with components in the rack, never extend more than one at a time.

Considerations for Cables

For optimal efciency in server operation and maintenance, follow these guidelines for handling cables connected to the server and other components in a rack.

m Plan to install the cable-management arm supplied with the server. If you dont install this device, you must disconnect all cables from the servers back panel before opening the server in the rack.

m Arrange all component cables so that they do not interfere with access to the rack. Ideally each component should have a cable-management option in place so that anyone servicing units in the rack can readily determine where each cable is connected.

m To ensure full signal strength for Ethernet, serial, and other connections, make sure cables do not exceed established length limits.

Preparing to Install Your Server 21

Security

Whatever the location of the server and rack, it should be secure.

m Determine that the racks location is secure and that only authorized staff members or technicians can gain access to this site.

m If using a server cabinet that is not stored in a secure room, be sure that the cabinet has adequate locking and that access to it is limited to authorized staff.

m Develop a plan for distributing and controlling keys to the server environment and access codes that will allow others to manage servers over the network. Keep the plan updated with names of key staff and relevant emergency information and procedures.

m Store a copy of essential server access information in a safe location away from the server site.

3 Installing Your Server in a Rack

Xserve is specically designed for rack mounting. It is not designed for use as a desktop machine.

You can install the server in several types of racks, including

m open four-post rack, 19 inches wide and 2936 inches deep

m cabinet with four-post rack inside, 19 inches wide and 2936 inches deep

m two-post (telecommunications, or telco) rack, 19 inches wide

The server is 1.75 inches (1U) high.

The brackets and screws necessary to attach the server to any of these racks are included with your server. You need to supply medium-sized and very small Phillips screwdrivers for the installation.

Warning Do not place a monitor on the server or use the top of the server as a shelf in the rack. Any weight on the servers enclosure could damage the components inside.

Important Any rack used for Xserve should meet the specications of the American National Standards Institute (ANSI)/Electronic Industries Association (EIA) standard ANSI/EIA-310-D-92, International Electrotechnical Commission (IEC) 297, and Deutsche Industrie Norm (DIN) 41494. See the documentation for the rack to determine whether it is compatible with these standards.

23

Installing the Server

As noted previously, you can install the server in a four-post or a two-post rack. Instructions for both procedures are given below. Preparations for installing are the same, whichever type of rack you use.

Get Ready to Install

Before beginning work with the server and rack, make the following preparations.

m If possible, arrange to work with another person as you prepare the server and install it in a rack.

m Assemble the tools, brackets, and connectors youll need for the installation. (All except the screwdrivers are provided with the server.)

m A medium-sized Phillips screwdriver. If you have a power screwdriver, use it.

m A very small Phillips screwdriver (needed for a four-post rack if you are attaching the cable-management arm).

m For a four-post rack, youll use two small brackets (each has two rivets), two long U-shaped braces, and eight mounting screws. Also get the cable-management arm and the two screws to attach it to the server.

m For a two-post rack, youll use two L-shaped brackets and eight screws.

Note: Two sets of screws are provided with the server. One set (English) is 10/32 inches in diameter; the other set is size M5 metric and t racks with metric holes. Check the documentation for your rack and use the appropriate set of screws; most racks use one of the two sizes. If screws are provided with your rack, you can use those as well.

m To measure and mark the position of the server in the rack, you may want to use a straightedge, such as a yardstick. Youll also need a pen or pencil and some masking tape or similar tape.

m Clear a table, cart, or other at surface near the rack. Youll need to put the server on it temporarily during installation, and you can use it to lay out the brackets and screws youll use to attach the server to the rack.

Determine the Position for the Server in the Rack

Review the guidelines for positioning the server in the rack. Then follow these steps to measure and mark its specic location.

1 Determine the exact position where you want to attach the server and mark it on one side of the rack.

Important Check the documentation for your rack for any special requirements.

24 Chapter 3

Some racks have marks at regular intervals (such as 1U) to aid in locating a server; others may provide a template to help place the server in the rack. If your rack does not have such aids, measure or count holes from an established point.

The distance between holes may vary somewhat on racks made by different manufacturers.

2 Use a straightedge to mark the same spot on the other side of the rack.

You can put a pencil mark or a piece of tape on each side of the rack to mark the correct spot.

For a four-post rack, measure and mark the posts at the front and back.

3 To verify that the position is correct, measure 1.75 inches (the servers height) down from the hole youve marked on the rack.

You measure downward because youll attach the cover of the servers enclosure to the rack, then slide the server into it.

Prepare the Server for Installation

If possible, work with another person as you prepare and install the server in a rack.

Follow these steps to prepare the server hardware for installation.

1 Unpack the server from its box and place it on the table

Follow the instructions in the booklet Quick Start for Xserve to unpack the server.

2 At the back of the server, write down the serial number from the servers back panel.

You will need the servers serial number to log in when you rst set up the server software.

Identify the appropriate holes in all mounting posts before you install the server so that it is mounted level.

Installing Your Server in a Rack 25

3 Remove the protective faceplate from the servers front panel by unscrewing the thumbscrews at each side of the faceplate and lifting it off.

Set the thumbscrews aside.

4 Loosen the two thumbscrews (one on each side) at the front of the servers enclosure.

These thumbscrews are captive and do not separate from the enclosure.

Remove the four thumbscrews that hold the protective faceplate in place, and remove the faceplate by lifting it straight up.

Protective faceplate

With the server resting on a flat, clean, and stable surface, unscrew the two thumbscrews on the front panel.

26 Chapter 3

5 Remove the cover of the servers enclosure by sliding it toward the back of the unit.

Hold the front thumbscrews to keep the main part of the server in place as you slide the cover toward the back.

6 When the cover is almost off, press the yellow release latches at the sides of the servers interior to release the cover, then take the cover off.

When youve removed the cover, set it aside.

With the server resting on a flat, clean, and stable surface, slide the cover completely to the rear. Press these two latches to release the cover from the server and remove it.

Installing Your Server in a Rack 27

7 If necessary, install any optional internal components, such as additional memory or a PCI card, in the server. Follow the appropriate instructions in Chapter 5, Installing or Replacing Server Components, on page 49.

8 If necessary, install any additional Apple Drive Modules in the front panel of the server. Follow the instructions in Installing or Replacing an Apple Drive Module on page 50.

28 Chapter 3

Note: When installing a drive module for the rst time, remove the blank drive module and save it for possible future use. This unit is necessary for appropriate cooling of the server in a drive bay that has no drive module in it.

When youve installed optional items, youre ready to connect the server to the rack. If you have a four-post rack or cabinet, proceed to the next section, Install the Server in a Four-Post Rack or Cabinet on page 29. If you have a two-post rack, go to Install the Server in a Two- Post (Telco) Rack on page 37.

Install the Server in a Four-Post Rack or Cabinet

A four-post rack can be open or enclosed in a cabinet. Examples of both racks are shown below. You follow the same steps to attach the server to either of these racks. For a cabinet, however, you may have to remove the door before installing the server.

Important Be sure to check the documentation for your rack for any specic mounting instructions.

Four-post open rack

Four-post cabinet rack

Installing Your Server in a Rack 29

Once youve marked the exact position for the server on the rack, youre ready to attach the server. Here is an overview of the procedure.

m Connect the cover of the server to the front of the rack.

m Assemble the rear mounting hardware.

m Connect the rear mounting hardware to the server enclosure.

m In a four-post rack, install the cable-management arm.

m Slide the server into the cover and secure it.

Follow these steps to attach the server to the rack.

1 Keep the cover of the enclosure level and support it from the center as you slide it into the rack at the desired position.

Important Work with someone else to make sure the cover is supported and square to the rack. The cover must be installed level to avoid changing its shape before the screws are inserted to hold it in place.

Have someone support the cover in the center while you attach it to the rack.

30 Chapter 3

2 Screw the anges at the front of the cover to the front rails of the rack

Be careful not to overtighten the ange screws. Doing so could change the shape of the cover slightly and make it difcult to slide the server into the cover.

Some racks have prethreaded holes and some have square holes that take clips with attached nuts. You may need to insert a clip (not provided with the server) into the appropriate hole before attaching the screw.

Attach the cover to the two front rack mounting posts using four of the screws provided.

Some racks have pre-threaded holes.

Other racks use various types of removable, captive nuts to secure equipment.

Installing Your Server in a Rack 31

3 At the back of the server, position the small bracket inside the servers cover so that the head of one rivet is facing the side of the cover.

Note: Start on the left side of the server (when facing the back). This makes installing the cable-management arm more efcient.

4 Push the rivet head through the hole thats near the back on the side of the cover.

The head of the rivet protrudes through the cover.

5 Position the long, U-shaped brace on the outside of the servers cover, so that the curved end is near the protruding rivet. The indented lip at the curved end of the brace should face the rivet head.

6 Slide the lip at the end of the brace over both rivets on the small bracket and continue to slide the brace forward a few inches.

Make sure the brace is on the outside of the cover and that both rivets are captured in the center opening of the brace.

Install the brackets on the inside of the top cover. The forward rivet on each bracket must pass through the hole in the cover.

Each bracket must be installed with the rivets oriented low on the bracket.

Slide the brace toward the front of the cover. Make sure that both rivets on the bracket have engaged the slot in the brace.

32 Chapter 3

7 Slide the brace forward or backward so that the at end of the brace is ush with the back rail of the rack and screw the braces ange to the rail.

Note: If you are installing the cable-management arm and your server is the same depth as your rack (or within an inch of it), only attach the brace to the rail on the left side of the server (as you face the back panel). You attach the cable-management arm along with the brace at the right rear of the server.

8 Attach the second bracket and brace, as described in steps 3 through 7.

Note: If your rack is deeper than the server, the braces and brackets extend beyond the servers back panel to the racks rails.

Install the Cable-Management Arm

Xserve has a cable-management arm that allows you to open the server without disconnecting cables. In addition, this device supports the cables and relieves strain on the servers back-panel connectors.

If your rack is the same depth as the server (or an inch or so deeper), you attach the cable- management arm to one rear post of the rack. If your rack is several inches deeper than the server, you attach the cable-management arm to one of the braces that supports the back of the server.

The steps that follow explain how to install the cable-management arm either to the rack or to the brace.

Attach the cover to the two rear rack mounting posts using four of the screws provided.

Important To open the server with the cables attached, you must install and use the cable- management arm.

Installing Your Server in a Rack 33

Attach the Cable-Management Arm to the Rack

1 If the rear rails of your rack are ush with the servers back panel or within an inch of it, position the cable-management arm so that the short side is closer to the servers back panel and the holes on the long side align with the holes on the brace on the right side.

2 Thread the hook-and-loop straps through the holes in the cable-management arm.

If the straps are already attached, skip this step.

3 Attach the long side of the folding arm to the rear rail, using two of the mounting screws provided with the server.

The cable-management arm attaches on top of the right brace. The mounting screws hold both in place.

See Connect Cables to the Server on page 40 for details on connecting cables and using the cable-management arm.

Attach the Cable-Management Arm to the Support Brace

If the rear rails of your rack are more than an inch away from the servers back panel, you need to attach the cable-management arm to the support brace at the side of the server (not to the rear rail). Otherwise the arm will not extend properly when you open the server in the rack.

1 Use a very small Phillips screwdriver to disconnect the small clamp that wraps around the long end of the cable-management arm (next to the two oval holes).

Youll use this clamp and screw to attach the arm to the brace.

Place the cable-management arm over the U-shaped brace, and secure both to the rack with two of the screws provided.

34 Chapter 3

2 Hold the cable-management arm with the long end closer to you and fold the hinged section of the long end away from you.

The hinged section is the part from which you removed the clamp and screw. This section should be perpendicular to the main part of the arm, with the oval holes furthest from you.

3 Position the cable-management arm so that the hinged section is on the inside of the right brace, about 2 inches behind the servers back panel.

4 Hold the arm in place and put the clamp you detached on the opposite side of the arm, so that the screw hole in the center shows through the open part of the brace.

5 Insert the screw into its hole and tighten it so that the arm is fastened to the brace.

6 Thread the hook-and-loop straps through the holes in the cable-management arm.

If the straps are already attached, skip this step.

See Connect Cables to the Server on page 40 for details on connecting cables and using the cable-management arm.

Mount the cable-management arm as close to the back of the server as possible. Rotate the mounting plate on the arm so that it lies against the inside of the U-shaped bracket. The U-shaped bracket should be sandwiched between the arm and the small clamp. Secure the clamp with the screw that held it stored on the arm.

Installing Your Server in a Rack 35

Place the Server in the Rack

Once youve attached the cable-management arm, you can put the server into the rack.

1 At the front of the rack, lift the server to the level where the enclosures cover is installed and slide the server into the cover.

2 Secure the server in the rack by tightening the thumbscrews on the front.

3 To further secure the server and prevent removal of the drive modules, use the enclosure key (supplied with the server) to fasten the security lock on the front panel. (See the illustration above.)

Insert the server into the cover and slide it all the way back.

To secure the drive modules in the server, use the enclosure key to lock them in place.

Tighten the two thumbscrews to secure the server in the rack.

36 Chapter 3

4 If youve installed the server in a cabinet, replace and close the cabinet door.

Once the server is secured in the rack or cabinet, you can attach cables for the servers connections.

See Connect Cables to the Server on page 40 for details of connecting cables and using the cable-management arm.

Install the Server in a Two-Post (Telco) Rack

The server attaches to a two-post rack at the center of the enclosure, so that the front and back of the server extend beyond the rack.

Follow these steps to install the server in a two-post rack. (These instructions assume that you have previously taken the cover off the server; see Prepare the Server for Installation on page 25 for details.)

Important Before installing the server in a two-post rack, make certain that the rack is securely fastened to the oor. Also check the racks documentation for any specic installation instructions.

Installing Your Server in a Rack 37

1 Attach the small L-shaped brackets to the sides of the server enclosures cover with four of the screws provided.

Orient the bracket so that the screws are at the top. Attach the brackets to holes that are about one-third of the way back from the front panel.

2 Position the cover in the rack at the desired location and screw the ange of the L-shaped bracket to the front of the rack on each side.

Be careful not to overtighten the ange screws. Doing so could change the shape of the cover slightly and make it difcult to slide the server into the cover.

Attach the two telco mounting brackets to the servers cover using the four screws provided.

Important Be sure to work with another person for this part of the installation. The cover should be held level to avoid changing its shape before the screws are inserted to hold it in place.

Attach the cover to the telco rack mounting posts using four of the screws provided.

38 Chapter 3

3 Lift the server to the level where the cover is installed and slide the server into the cover.

4 Secure the server in the rack by tightening the thumbscrews on the front.

5 To further secure the server and prevent removal of the drive modules, use the enclosure key (supplied with the server) to fasten the security lock on the servers front panel. (See the illustration above.)

Note: You cannot use the cable-management arm on an Xserve system that is installed in a two-post rack.

Insert the server into the cover and slide it all the way back.

Tighten the two thumbscrews to secure the server in the rack.

To secure the drive modules in the server, use the enclosure key to lock them in place.

Installing Your Server in a Rack 39

Connect Cables to the Server

Once the server is secured in the rack, you can connect the cables and power cord to its back and front panels.

Follow these steps to connect cables for network connections and peripheral devices.

1 Assemble the cables and devices you will connect to the servers back panel. Make certain that each cable has the proper connector and that it is designed for use in a high-capacity server. (Check the documentation for each peripheral device or cable to determine that it can be used with the server.)

2 Attach an identifying label to each cable you are connecting.

The labels allow you to locate a specic cable quickly and avoid errors when disconnecting cables.

3 Beginning at one side of the servers back panel, connect each cable to its respective port.

Do not attach the power cord yet.

Important If you use the cable-management arm, your cables must be approximately 3 feet longer than the distance between the server and its peripheral devices. This extra length may not be feasible for some cables, such as SCSI cables. In this instance, you can bypass the cable-management arm with a shorter cable. But you must disconnect that cable when you open the server.

40 Chapter 3

4 Arrange all the cables on the back panel in the cable-management arm and secure them with the straps provided with the cable-management arm.

The cable-management arm can only be used with a four-post rack or cabinet.

If you are not using the cable-management arm, skip this procedure. Its a good idea to group the cables and arrange them so that they dont cause any hazard and are easy to handle should you need to detach them when opening the server.

a Group the cables together loosely and fold them to the right side of the back panel, until they are near the short (inner) end of the cable-management arm.

b Reverse the direction of the cables and lay them along the edge of the cable-management arm closest to the servers back panel.

c Attach the cables to the arm with the straps provided.

Wrap the cables so that the sides of facing straps do not stick to each other.

d Reverse the direction of the cables again and lay them along the edge of the cable- management arm furthest from the back panel.

e Attach the cables to the arm with the straps provided.

5 Connect the power cord to the back panel.

Gather all the cables attached to the server except the power cord, and attach them to the cable-management arm. Use the hook-and-loop fastener straps to secure the cables to the arm.

Make sure you lay the cables against the full length of the cable-management arm to assure unobstructed extension.

Installing Your Server in a Rack 41

6 Attach the power cords retainer clip to the back panel to keep the power cord in place when you open the server.

The ends of the clip t into the small openings at either side of the power socket. Be sure that the rounded part of the clip goes under the cord, so that the cord is supported.

If more than one power cord came with your server, use the appropriate cord for the electrical service available at your location.

You can use the long power cord supplied with the server, or another cord, such as one already installed in the rack.

7 If you will be using the FireWire port on the front panel of the server, connect a cable to it.

8 When all cables are in place, connect each one to its intended device.

Attach the power cord retainer clip to the two loops on the back of the server. Snap the cord into the clip so that it cradles the cord.

Important When connecting peripheral devices, be sure to allow adequate space at the front and back of the server for proper airow and access to the rack for servicing.

42 Chapter 3

9 After all connections are complete, plug the power cord into a power source.

With the server in the rack and the cables in place, you can prepare to set up the Mac OS X Server software.

Preparing the Server for Software Setup

When the server is installed and secured, you are ready to set up the software.

You can congure the server locally or use the remote setup tools. If you want to congure the server software where the server and rack are located, you can do one of the following:

m Connect a monitor, keyboard, and mouse to the server.

You can connect the monitor to the VGA port and connect the keyboard and mouse to the USB ports on the servers back panel. If a KVM (keyboard-video-mouse) switch is installed in the rack, you can use it. See the documentation for the KVM switch for instructions.

m Connect a computer running Mac OS X to the server using an Ethernet connection on the same subnet as the server.

If you want to set up the software from another location, you can work at a computer on the servers network, using the remote server administration software and command-line tools. You need to install the administration software on the portable or network computer before you can set up the software.

See Chapter 4, Using Your Server, on page 45 for more about software conguration.

Warning This equipment is intended to be electrically grounded. Your server is equipped with a three-wire grounding pluga plug that has a third (grounding) pin. This plug will t only a grounded AC outlet. This is a safety feature. If you are unable to insert the plug into the outlet because the outlet is not grounded, contact a licensed electrician to replace the outlet with a properly grounded outlet. Do not defeat the purpose of the grounding plug!

Because you are installing the server in a rack with other equipment, be certain that the power outlet and any other equipment, such as a power strip, used with the rack is designed to carry the electrical load of multiple devices. Check the documentation for your rack for any special instructions.

Adding Memory

The server has four memory slots, at least one of which is lled at the factory. Follow these steps to add memory to the server.

You can install additional dynamic random-access memory (DRAM) in packages called Dual Inline Memory Modules (DIMMs) in the four DRAM DIMM slots on the servers main logic board. You can expand your computers DRAM to a maximum of 2 gigabytes (GB). To check the amounts of DRAM installed, use the Apple System Proler (located in the Utilities folder, in your computers Applications folder).

DIMMs must t these specications:

m PC2100 double-data-rate (DDR) Synchronous DRAM (SDRAM); also described as DDR-266

m 2.5 volt ( V )

m 64-bit wide, 184-pin module

m Maximum number of memory devices on a DIMM is 16.

m Unbuffered; do not use registered or buffered DRAM.

m Height must not exceed 1.25 inches.

Note: When purchasing DRAM for use in the server, make sure that the memory conforms to the JEDEC specication. Check with your memory vendor to ensure that the DRAM DIMM supports the correct timing modes and that the Serial Presence Detect (SPD) feature has been programmed properly, as described in the JEDEC specication. You can purchase memory where you bought your server.

Follow these steps to install memory in the server.

Important Safety Information

For your own safety and that of your equipment, always take the following precautions.

Disconnect the power plug (by pulling the plug, not the cord) if any of the following conditions exists:

m you want to remove any parts (leave the cord disconnected as long as the cover is off )

m the power cord or plug becomes frayed or otherwise damaged

m you spill something into the case

m your server is exposed to rain or any other excess moisture

m your server has been dropped or the case has been otherwise damaged

m you suspect that your server needs service or repair

m you want to clean the case (use only the recommended procedure described later)

Be sure that you always do the following:

m Keep your server away from sources of liquids, such as washbasins, bathtubs, shower stalls, and so on.

m Protect your server from dampness or wet weather, such as rain, snow, and so on.

m Read all the installation instructions carefully before you plug your server into a wall socket or power strip.

m Keep these instructions handy for reference by you and others.

m Follow all instructions and warnings dealing with your system.

Electrical equipment may be hazardous if misused. Operation of this product, or similar products, must always be supervised by an adult. Do not allow children access to the interior of any electrical product and do not permit them to handle any cables.

Important The only way to disconnect power completely is to unplug the power cord. Make sure at least one end of the power cord is within easy reach so that you can unplug the server when you need to.

73

Handling Your Computer Equipment

Follow these guidelines for handling your computer and its components:

m When the server is removed from its rack, set it on a sturdy, at surface.

m When connecting or disconnecting a cable, always hold the cable by its connector (the plug, not the cord).

m Turn off your server before connecting or disconnecting a cable for a monitor or a serial device. Failure to do so could damage your equipment or cause an interruption in the servers operation.

Certain components and cableshard disks, a VGA monitor, FireWire, Ethernet, and USB devicesare designed to be installed or removed while the server is turned on and operating.

m Never force a connector into a port. If the connector and port do not join with reasonable ease, they probably dont match. Make sure that the connector matches the port and that you have positioned the connector correctly in relation to the port.

m Take care not to spill any food or liquid on the server or other components. If you do, turn your server off immediately and unplug it before cleaning up the spill. Depending on what you spilled and how much of it got into your equipment, you may have to arrange for an Apple-authorized service provider to inspect or repair the server.

m Protect the server and its components from direct sunlight and rain or other moisture.

m Keep all ventilation openings clear and unobstructed. Without proper air circulation, components can overheat, causing damage or unreliable operation.

Important Do not put a monitor or any other device on top of the server. Essential components are installed in this low-prole server, and any weight on top of the case could damage these components.

74 Appendix B

Protecting Your CD Drive

To keep your CD drive working properly:

m Position your server so that when the tray opens, it doesnt bump into anything.

m Do not leave the disc tray open. If dust gets on the lens of the CD-ROM drive, the drive may have problems reading your discs.

m Do not put anything (for instance, a cup) on top of the tray when it is open.

m Do not force the tray open by hand. In an emergency, you can use an opened paper clip in the tiny hole near the drive to eject a disc.

m Do not wipe the lens with a paper towel or other abrasive surface. If you need to clean the lens, see an Apple-authorized service provider for a lens cleaner.

You may want to open the tray and take out your disc before shutting down.

Power Supply

The power supply in your computer is a high-voltage component and should not be opened for any reason, even when the computer is off. If the power supply needs service, contact your Apple-authorized dealer or service provider.

Cleaning Your Equipment

Follow these general rules when cleaning the outside of your server:

m Use a damp, soft, lint-free cloth to clean the computers exterior. Avoid getting moisture in any openings.

m Dont use aerosol sprays, solvents, or abrasives.

Cleaning the Servers Case

To clean the case, do the following:

1 Turn off the computer completely and then disconnect the power plug. (Pull the plug, not the cord.)

2 Wipe the surfaces lightly with a clean, soft cloth dampened with water.
