Replacement Instructions

Follow the instructions in this sheet carefully. Failure to follow these instructions could damage your equipment and void its warranty.

Note:

Online instructions covering customer-installable parts are available at http://www.info.apple.com/installparts/.

Note:

These instructions apply to the locking mechanism rod and gear of different versions of Xserve/Xserve G5. While your server may look slightly different from the one shown in the illustrations, the procedures for all versions are the same.

Tools Required

No tools are required for this procedure. You may, however, nd a Phillips screwdriver useful in releasing the thumb screws at the front of the server.

Opening the Server

The server slides open from the front of the rack. The top cover remains in place in the rack while the bottom housing (containing all internal components) should be placed on a sturdy, at surface.

1. Alert users that the server will be unavailable for a period of time.

2. Shut down the server.

Warning: To avoid damaging internal components or causing injury, always shut down the server before opening it. After you shut down the server, internal components can be very hot. Let the server cool down before continuing.

3. Write down the servers serial number, which is located on the back panel. If it is necessary to set up the servers software after you replace the locking mechanism rod and/or gear, you will be asked for the serial number at login.

4. If the server is in the locked position (the yellow security LED on the front panel is on), use the Allen key that came with the server to unlock it.

5. If the cable management arm is not in use, unplug all external cables except the power cord.

6. Touch the servers metal case to discharge any static electricity.

Important:

Always ground yourself by touching the servers case before you touch any parts or install any components inside the server. To avoid static electricity building back up in your body, do not walk around the room until you have completed your work and closed the computer.

7. Unplug the power cord.

Warning: The power supply in the server is a high-voltage component and should not be opened for any reason, even when the server is off.

8. Release the two thumb screws at the front of the server.

Note:

The thumbscrews are captive and do not separate from the bottom housing.

Installing the Replacement Locking Mechanism Rod and Gear

Closing the Server
