Before You Begin Go over all data center requirements and planning tasks before you begin.
Topics:
Overview of data center requirements PowerMax packaging Tasks to review
Overview of data center requirements PowerMax arrays are designed for installation in data centers that provide:
Sufficient physical space Controlled temperature and humidity Airflow and ventilation Power and grounding System cable routing facilities Fire protection
Raised floors are preferred.
For information regarding overhead cable routing, see Overhead routing kit on page 71.
To prepare the site for an array, meet with your Dell Systems Engineer and Customer Engineer to determine what is needed to prepare for delivery and installation. One or more sessions may be necessary to finalize installation plans.
PowerMax packaging The basic building block of a PowerMax array is the PowerMax Brick (on arrays in open systems environments) or PowerMax zBrick (on arrays in a mainframe environment). Depending on the array this consists of:
An engine with two directors (the redundant data storage processing unit) Flash storage in two Drive Array Enclosures (DAEs) each with 24 slots Minimum storage capacity:
PowerMax 2000: 13 TBu (Terabytes usable) PowerMax 8000 in an open systems environment: 53 TBu PowerMax 8000 in a mainframe environment: 13 TBu PowerMax 8000 in a mixed open systems and mainframe environment: 66 TBu
This document uses the term PowerBrick for planning purposes. All guidelines that apply to PowerBricks also apply to PowerMax zBricks.
Tasks to review The following table provides a list of tasks to review during the planning process:
Table 3. Planning tasks
Task Comments and/or Provide
Identify power requirements with site electrician. External AC power must be supplied from independent customer-supplied redundant power distribution units (PDUs).

Before You Begin 9
Table 3. Planning tasks (continued)
Task Comments and/or Provide
Dell recommends that the customers electrician be available at the installation site for regular and third party racked arrays. If flying leads are used an electrician must connect the power. The connector type must be verified as part of the installation plan.
Best Practices for AC Power Connections on page 73 provides details.
For third-party rack support, see the detailed physical requirements in Third Party Racking Option for PowerMax 2000 on page 56 and Third Party Racking Option for PowerMax 8000 on page 63.
The field representative working the order must:
Review the requisite information regarding the third party racking option.
In PowerSizer, select the configuration. In the Hardware Options screen, under Rack Type, select Third Party.
10 Before You Begin
Delivery and Transportation Components are shipped directly to customer data centers. Arrangements should be made to receive the equipment.
Topics:
Delivery arrangements Pre-delivery considerations Moving up and down inclines Shipping and storage environmental requirements
Delivery arrangements Delivery within the United States or Canada is by air-ride truck with custom-designed shipping material, crate, and pallet. International delivery normally involves air freight.
Unless otherwise instructed, the Dell Traffic Department arranges for delivery directly to the customers computer room. To ensure successful delivery of the system, Dell has formed partnerships with specially selected moving companies. These companies have moving professionals trained in the proper handling of large, sensitive equipment and provide the appropriate personnel, floor layments, and any ancillary moving equipment required to facilitate delivery. Moving companies should check general guidelines, weights, and dimensions.
NOTE: Inform Dell of any labor union-based restrictions or security clearance requirements prior to delivery.
Pre-delivery considerations Take into account the following considerations prior to the delivery at your site:
Weight capacities of the loading dock, tailgate, and service elevator if delivery is to a floor other than the receiving floor. Length and thickness of covering required for floor protection. Equipment ramp availability if the receiving floor is not level with computer room floor. Set up the necessary network and gateway access to accommodate Secure Remote Services so that it will be available and
operable for the installation date.
Moving up and down inclines To prevent tipping when moving up and down inclines, close all doors and drawers. Push from the rear of the rack so that the front (side with bezels or a fancy door) goes first.
All portions of the bay will clear ramp and threshold slopes up to 1:10 (rise to run ratio), per Code of Federal Regulations ADA Standards for Accessible Design, 28 CFR Part 36.

System Specifications System specifications include minimum and maximum power consumption and heat dissipation values, temperature and humidity requirements, sound power and pressure levels, and other specifications.
Topics:
Radio frequency interference Power consumption and heat dissipation Airflow Air volume, air quality, and temperature Shock and vibration Sound power and sound pressure Hardware acclimation times Optical multimode cables
Radio frequency interference Electro-magnetic fields, which include radio frequencies can interfere with the operation of electronic equipment. Dell products have been certified to withstand radio frequency interference (RFI) in accordance with standard EN61000-4-3. In Data Centers that employ intentional radiators, such as cell phone repeaters, the maximum ambient RF field strength should not exceed 3 Volts /meter.
The field measurements should be taken at multiple points in close proximity to Dell equipment. It is recommended to consult with an expert prior to installing any emitting device in the Data Center. In addition, it may be necessary to contract an environmental consultant to perform the evaluation of RFI field strength and address the mitigation efforts if high levels of RFI are suspected.
The ambient RFI field strength is inversely proportional to the distance and power level of the emitting device.
Recommended minimum distance from RF emitting device
The following table provides the recommended minimum distances between Dell arrays and RFI emitting equipment. Use these guidelines to verify that cell phone repeaters or other intentional radiator devices are at a safe distance from the equipment.
Table 5. Minimum distance from RF emitting devices
Repeater power levela Recommended minimum distance
1 Watt 9.84 ft (3 m)
2 Watt 13.12 ft (4 m)

Power consumption and heat dissipation Use the Dell Power Calculator to refine the power and heat figures to more closely match your array. Contact your sales representative or use the Power Calculator for specific supported configurations. The following table provides calculations of maximum power and heat dissipation.
NOTE: Power consumption and heat dissipation details vary based on the system configuration, I/O activity, and ambient
temperatures. Ensure that the installation site meets these worst case requirements. The numbers in Power consumption
and heat dissipation on page 14 are for fully stacked bays for a single system.
Table 6. Power consumption and heat dissipation
PowerMax 2000 PowerMax 8000
Maximum power and heat dissipation at <26C and >35C a
Maximum total power consumption <26C / >35C (kVA)

System bay 2 N/A 8.0 / 11.4 27,214 / 38,665
a. Power values and heat dissipations shown at >35C reflect the higher power levels associated with both the battery recharge cycle, and the initiation of high ambient temperature adaptive cooling algorithms. Values at <26C are reflective of more steady state maximum values during normal operation.
b. Values do not include a 100W power draw for the service tray line cord attached to a customer service laptop.
14 System Specifications
Adaptive cooling
The systems apply adaptive cooling based on customer environments to save energy. Engines and DAEs access thermal data through components located within their enclosures. Based on ambient temperature and internal activity, they set the cooling fan speeds. As the inlet temperatures increase, the adaptive cooling increases the fan speeds, with the resulting platform power increasing up to the maximum values shown below. These values, along with the SPS recharge power consumption, contribute to the maximum system power consumption values over 35C shown in Power consumption and heat dissipation on page 14.
PowerMax 2000 and PowerMax 8000
DAE24 (24 Drives) = 206 VA - 702 BTU/hr Engine = 255VA - 870 BTU/hr
System Specifications 15
Airflow Systems are designed for typical hot aisle/cold aisle data center cooling environments and installation:
On raised or nonraised floors. In hot aisle/cold aisle arrangements.
The airflow provides less mixing of hot and cold air, which can result in a higher return temperature to the computer room air conditioner (CRAC). This promotes better heat transfer outside the building and achieves higher energy efficiency and lower Power Usage Effectiveness (PUE). Additional efficiency can be achieved by sequestering the exhaust air completely and connecting ducts directly to a CRAC unit or to the outside.
Best practice is to place a perforated floor tile in front of each bay to allow adequate cooling air supply when installing on a raised floor. The following figure shows typical airflow in a hot aisle/ cold aisle environment.

Air quality requirements
PowerMax arrays are designed to be consistent with the requirements of the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) Environmental Standard Handbook and the most current revision of Thermal Guidelines for Data Processing Environments, ASHRAE TC 9.9 2011.
System Specifications 17
The arrays are best suited for Class 1A Datacom environments, which consist of tightly controlled environmental parameters, including temperature, dew point, relative humidity and air quality. These facilities house mission critical equipment and are typically fault tolerant, including the air conditioners. In a data center environment, if the air conditioning fails and the temperature is lost, a vault may occur to protect data.
The data center should maintain a cleanliness level as identified in ISO 14664-1, class 8 for particulate dust and pollution control. The air entering the data center should be filtered with a MERV 11 filter or better. The air within the data center should be continuously filtered with a MERV 8 or better filtration system. In addition, efforts should be maintained to prevent conductive particles, such as zinc whiskers, from entering the facility.
The allowable relative humidity level is 2080% non condensing, however, the recommended operating environment range is 4055%. For data centers with gaseous contamination, such as high sulfur content, lower temperatures and humidity are recommended to minimize the risk of hardware corrosion and degradation. In general, the humidity fluctuations within the data center should be minimized. It is also recommended that the data center be positively pressured and have air curtains on entry ways to prevent outside air contaminants and humidity from entering the facility.
For facilities below 40% relative humidity (RH), Dell recommends using grounding straps when contacting the equipment to avoid the risk of electrostatic discharge (ESD), which can harm electronic equipment.
NOTE: As part of an ongoing monitoring process for the corrosiveness of the environment, Dell recommends placing copper
and silver coupons (per ISA 71.04-1985, Section 6.1 Reactivity) in airstreams representative of those in the data center. The
monthly reactivity rate of the coupons should be less than 300 Angstroms. When monitored reactivity rate is exceeded, the
coupon should be analyzed for material species and a corrective mitigation process put in place.
18 System Specifications
Shock and vibration The following table provides the platform shock and vibration maximums and the transportation shock and vibration levels (in the vertical direction).
NOTE: Levels shown apply to all three axes, and should be measured with an accelerometer in the equipment enclosures

Topics:
Fire suppressant disclaimer Remote support
Fire suppressant disclaimer Fire prevention equipment in the computer room should always be installed as an added safety measure. A fire suppression system is the responsibility of the customer. When selecting appropriate fire suppression equipment and agents for the data center, choose carefully. An insurance underwriter, local fire marshal, and local building inspector are all parties that you should consult during the selection of a fire suppression system that provides the correct level of coverage and protection.
Equipment is designed and manufactured to internal and external standards that require certain environments for reliable operation. We do not make compatibility claims of any kind nor do we provide recommendations on fire suppression systems. It is not recommended to position storage equipment directly in the path of high pressure gas discharge streams or loud fire sirens so as to minimize the forces and vibration adverse to system integrity.

22 Data Center Safety and Remote Support
Physical Weight and Space Physical weight and space requirements include floor load-bearing capacity, raised floor requirements and physical space and weight specifications.
Topics:
Floor load-bearing capacity Raised floor requirements Physical space and weight Component dimensions, PowerMax 2000 Component dimensions, PowerMax 8000
Floor load-bearing capacity Storage arrays can be installed on raised floors. Customers must be aware that the load-bearing capacity of the data center floor is not readily available through a visual inspection of the floor. The only definitive way to ensure that the floor is capable of supporting the load associated with the array is to have a certified architect or the data center design consultant inspect the specifications of the floor to ensure that the floor is capable of supporting the array weight.
CAUTION:
Customers are ultimately responsible for ensuring that the floor of the data center on which the array is to
be configured is capable of supporting the array weight, whether the array is configured directly on the data
center floor or on a raised floor supported by the data center floor.
Failure to comply with these floor loading requirements could result in severe damage to the storage array,
the raised floor, subfloor, site floor and the surrounding infrastructure should the raised floor, subfloor or
site floor fail.
Notwithstanding anything to the contrary in any agreement between Dell and the customer, Dell fully
disclaims any and all liability for any damage or injury resulting from the customers failure to ensure that
the raised floor, subfloor and/or site floor are capable of supporting the storage array weight. The customer
assumes all risk and liability associated with such failure.
Raised floor requirements Best practice is to use 24 x 24 inch heavy-duty, concrete-filled steel floor tiles. If a different size or type of tile is used, the customer must ensure that the tiles have a minimum load rating that is sufficient for supporting the storage array weight. Ensure proper physical support of the system by following requirements that are based on the use of 24 x 24 in. (61 x 61 cm) heavy-duty, concrete-filled steel floor tiles.
Raised floors must meet the following requirements:
Floor must be level. Floor tiles and stringers must be rated to withstand concentrated loads of two casters each that weigh up to 600 lb (272
kg).
NOTE: Caster weights are measured on a level floor. The front of the array weighs more than the rear of the configuration.
Floor tiles and stringers must be rated for a minimum static ultimate load of 2,500 lb (1,134 kg). Floor tiles must be rated for a minimum of 750 lb (340 kg) on rolling load. For floor tiles that do not meet the minimum rolling load rate, Dell recommends the use of coverings, such as plywood, to
protect floors during system roll.
5
Physical Weight and Space 23
Floor tile cutouts weaken the tile. An additional pedestal mount adjacent to the cutout of a tile can minimize floor tile deflection. The number and placement of additional pedestal mounts relative to a cutout should be in accordance with the tile manufacturers recommendations.
Take care when positioning the bays to make sure that a caster is not moved into a cutout. Cutting tiles per specifications ensures the proper caster placement.
Use or create no more than one floor tile cutout that is no more than 8 in. (20 cm) wide by 6 in. (15 cm) deep in each 24 x 24 in. (61 x 61 cm) floor tile.
Ensure that the weight of any other objects in the data center does not compromise the structural integrity of the raised floor or the sub-floor (non-raised floor) of the data center.
Physical space and weight The following table provides the physical space, maximum weights, and clearance for service.

Power Cabling, Cords and Connectors PowerMax systems support single-phase, three-phase Delta and three-phase Wye wiring configurations.
Topics:
Power distribution units Power interface Customer input power cabling Best practices: Power configuration guidelines AC power specifications Power cords PowerMax 2000 line cord and jumper configurations PowerMax 8000 line cord and jumper configurations
Power distribution units CAUTION: Dell PDUs are designed to be mounted securely in Dell racks. They are not intended for third party
racks.
PowerMax systems are powered by two redundant power distribution units (PDUs), one for each power zone. The PDUs are available in three wiring configurations:
Single-phase Three-phase Delta Three-phase Wye
The AC power cords (single-phase and three-phase) extend above the bay egress for connection to the customer power supply. 15ft (4.57M) power cords that plug into the bottom of the PDUs are provided. For single-phase, more than one power cord per power zone may be required.
The AC cords can be routed out either the bottom or the top of the rack. If the customer requires power to be supplied from overhead, Dell recommends replacing the rear top cover of the bay with the ceiling routing top cover, which allows the power cables inside the machine to be routed out through the top.
A second option is to "drop" the power cables down the hinge side, to the bottom, and route them inside the machine. The cables should be dressed to allow all doors to open freely and space should be provisioned accordingly to accommodate an adjacent cabinet.
If the customer requires power to be supplied from overhead, the Overhead Routing Kit is available to route the power cables inside the machine through the top. Extension cables are not provided. See Optional Kits on page 71 for information on optional kits.
NOTE: Utilize proper strain relief methods when customer-provided power drops are located overhead or wall-mounted.
Power interface Data centers must conform to the corresponding specification for arrays installed in North American, International, and Australian sites.
Customers are responsible for meeting all local electrical safety requirements.

Power Cabling, Cords and Connectors 39
Customer input power cabling Before the array is delivered, the customer must supply and install the required receptacles on their PDUs for zone A and zone B power for each system bay.
Dell recommends that the customer's electrician be present at installation time to work with the Dell customer engineer to verify power redundancy.
Refer to the Dell EMC Best Practices Guide for AC Power Connections for PowerMax 2000, 8000 with PowerMaxOS for required items at the customer site.
Best practices: Power configuration guidelines The following section provides best practice guidelines for evaluating and connecting power, as well as for choosing a UPS component.
Uptime Institute best practices
Follow these best practice guidelines when connecting AC power to the array:
The Dell customer engineer (CE) should discuss with the customer the need for validating AC power redundancy at each bay. If the power redundancy requirements are not met in each bay, a Data Unavailable (DU) event could occur.
The customer should complete power provisioning with the data center prior to connecting power to the array. The customers electrician or facilities representative must verify that the AC voltage is within specification at each of the
power drops being fed to each product bay. All of the power drops should be labeled to indicate the source of power (PDU) and the specific circuit breakers utilized
within each PDU: Color code the power cables to help achieve redundancy. Clearly label the equipment served by each circuit breaker within the customer PDU.
The electrician or facilities representative must verify that there are two power drops fed from separate redundant PDUs prior to turning on the array: If both power drops to a bay are connected to the same PDU incorrectly, a DU event will result during normal data center
maintenance when the PDU is switched off. The label on the power cables depicts the correct connection. The electrician should pay particular attention to how each PDU receives power from each UPS within the data center
because it is possible to create a scenario where turning off a UPS for maintenance could cause both power feeds to a single bay to be turned off, creating a DU event.
The customers electrician should perform an AC verification test by turning off the individual circuit breakers feeding each power zone within the bay, while the customer engineer monitors the LED on the SPS modules to verify that power redundancy has been achieved in each bay.
One customer PDU should never supply both power zone feeds to any one rack of equipment.

Grounding Racks Supplemental rack grounding is not required for single bay configurations. Chassis to chassis grounding is required for systems with multiple bays.
Topics:
Grounding requirements Grounding a single bay Chassis to chassis grounding
Grounding requirements The following table summarizes rack grounding requirements for PowerMax systems.
Number of racks in system Grounding required? Reference
1 No Grounding a single bay on page 50
2+ Yes Chassis to chassis grounding on page 51
Grounding a single bay Equipment correctly installed within the cabinet is grounded through the AC power cables and connectors. In general, supplemental grounding is not required for a single bay.
If your site requires external grounding (for example, to a common grounding network beneath the site floor), you can use the grounding lugs provided on each of the cabinets bottom supports.

Figure 17. Location of cabinet ground lugs
Chassis to chassis grounding Rack to rack chassis ground connections are required to mitigate the risk of large AC power transients in the data center affecting system performance. Large AC power transients can occur from one or a combination of: electrical power grid problems feeding a facility; weak facility grounding; powerful lightning storm strikes; or facility power equipment failure.
In multiple bay Dell rack systems, use the rack to rack grounding kit, PN 106-562-209, to provide chassis to chassis grounding. The kit provides straps for both the front and rear of the cabinets. Both straps must be installed to provide chassis to chassis grounding.
In customer rack systems, mechanisms for tying racks together to provide the ground connection can vary based on the rack provided by the customer and site facility preference. PN 106-562-209 is a rack to rack grounding kit for Dell racks. The grounding kit may or may not work on racks provided by the customer due to the variety of ground location positions on racks. If the grounding kit does not work, a site electrician should add a ground cable tying the two racks common frame ground points together with 6AWG wire.

Requirements for customer components in a rack Customer components can coexist in a rack with a PowerMax 2000 system. The system must be properly positioned within the rack in accordance with the following rules:
Dell equipment should stack from the bottom of the rack. Customer equipment stacks from the top of the rack. A system must exist within contiguous space. Customer equipment must be above a PowerMax 2000 system and not
interwoven within the system. All customer equipment must be electrically isolated and powered by the upper half of the PDUs and powered by separate
power cords. The power cord pairs listed in Power cords on page 41 are available as optional models. Racks with two PowerMax 2000 systems cannot have customer components installed in the rack.
Dell Racking for PowerMax 2000 55
Third Party Racking Option for PowerMax 2000
The PowerMax 2000 can be installed in a third party rack if computer room, rack and PDU requirements are met.
Topics:
Computer room requirements Customer rack requirements Third party rack PDUs
Computer room requirements
The following computer room requirements provide service access and minimize physical disruption:
A minimum of 42 inches (107 cm) front and 30 inches (76 cm) rear clearance is required to provide adequate airflow and to allow for system service.
Customer rack requirements The array components are fully tested at the factory and then transferred to the shipping rack for shipping. Only Customer Support engineers are authorized to install the system into a customer rack. The original shipping rack, when empty, is returned after the installation is complete.
To ensure successful installation and secure component placement, customer racks must conform to the following requirements:
The National Electrical Manufacturers Association (NEMA) standard for 19-inch cabinets. Racks must be at least 38 inches deep as measured from the surface of the front NEMA rail to the rear rack post, and
provide 24 to 32-inch front-to-rear NEMA rail depth. Systems require a minimum of 10U of continuous space for one PowerBrick (minimum configuration). 20U of continuous
space is required for two PowerBricks (maximum configuration). Threaded hole racks are not supported. The customer rack must have two redundant, customer-supplied PDUs installed, one on each side. Each must be connected
to customer power. The customer rack must support a minimum 850 lbs (385 kg) of weight plus the weight of any third-party components
within the rack.
NOTE: The customer must ensure that floor load bearing requirements are met.
After installation, components and cables within the rack cannot be moved to available space in a different rack or to a different location within the same rack.
Systems must be properly positioned within the rack in accordance with the following physical placement rules: Customer equipment can co-exist within the same rack. The preferred stack up is for the Dell array to stack from the
bottom of the rack and customer equipment from the top of the rack. A Dell system must exist within contiguous space. Customer equipment can be below or above the system, but not
interwoven within the system. A single PowerBrick system must occupy 10U of continuous space, and a dual PowerBrick system must occupy 20U of continuous space in the rack.
Two, independent Dell systems can co-exist in a rack. The recommended configuration is: Lower system: 1U - 20U Upper system 21U - 40U
Round or square channel openings must support M5 screws that secure rails and components. Clip nuts are provided as required.
11
56 Third Party Racking Option for PowerMax 2000
All array components must have proper clearance and air flow. Customer-supplied front doors and standard bezels must include a minimum of 2.5 in (6.3 cm) clearance between the back surface of the door to the front surface of the vertical NEMA rails.
Front and rear doors must also provide:
A minimum of 60% (evenly distributed) air perforation openings Appropriate access for service personnel, with no items that prevent front or rear access to components Exterior visibility of system LEDs
Third Party Racking Option for PowerMax 2000 57
Third party rack PDUs Each system bay is powered by redundant power distribution units (PDUs), one PDU for each power zone. The general requirements for third-party racks with vertical rear-facing or inward-facing PDUs are listed below.
General requirements for vertical PDUs within third-party racks
In addition to meeting standard PowerMax array power requirements, PDUs should abide by the following:
Both PDUs support AC-line input connectivity and provide outlets for every component in the bay. The PDU must be available in the wiring configuration that matches the customer input power configuration.
Options include:
Single-phase Three-phase Delta Three-phase Wye (International and Domestic)
Each PDU should meet the following requirements: At a minimum, a total of three (3) C13 power outlets per PowerBrick must be provided. Each bank of outlets is connected to individual branch circuits that are protected by a single two pole 20 Amp circuit
breaker. The PDU capacity should exceed the power requirements shown in the tables in PowerMax 2000 power consumption and
outlet requirements on page 59 for the specific maximum configuration. The PDU is mounted symmetrically on each side of a rack.
If the customer requires power to be supplied from overhead, Dell recommends one of the following:
Option 1: If possible, route the power cables from inside the machine through the top of the rack. Option 2: "Drop" the power cables down the hinge side, to the bottom, and route them inside the machine.
In either case, dress the power cables to the side walls so they do not get in the way of service. The cables should be dressed to allow all doors to open freely, minimize cable congestion, and provide access to components within the system.

64 Third Party Racking Option for PowerMax 8000
Third party rack PDUs Each system bay is powered by two redundant power distribution units (PDUs), one PDU for each power zone. The general requirements for third-party racks with vertical rear-facing or inward-facing PDUs are listed below.
General requirements for vertical PDUs within third-party racks
In addition to meeting standard PowerMax array power requirements, PDUs should abide by the following:
Both PDUs support AC-line input connectivity and provide outlets for every component in the bay. The PDU must be available in the wiring configuration that matches the customer input power configuration.
Options include:
Single-phase Three-phase Delta Three-phase Wye (International and Domestic)
PowerMax 8000 power consumption and outlet requirements on page 66 details the number of C13 outlets required for each PowerBrick. Each PDU should meet the following requirements: Each bank of outlets is connected to individual branch circuits that are protected by a single two pole 20 Amp circuit
breaker. The PDU capacity should exceed the power requirements shown in the tables in PowerMax 8000 power consumption and
outlet requirements on page 66 for the specific maximum configuration. The PDU is mounted symmetrically on each side of a rack.
If the customer requires power to be supplied from overhead, Dell recommends one of the following:
Option 1: If possible, route the power cables from inside the machine through the top of the rack. Option 2: "Drop" the power cables down the hinge side, to the bottom, and route them inside the machine.
In either case, dress the power cables to the side walls so they do not get in the way of service. The cables should be dressed to allow all doors to open freely, minimize cable congestion, and provide access to components within the system.

Best Practices for AC Power Connections 73
Best practices overview for AC power connections To assure fault tolerant power, external AC power must be supplied from independent, customer-supplied, power distribution units (PDUs) as shown in Two independent customer-supplied PDUs on page 74.
For systems operating from three phase AC power, two independent and isolated AC power sources are recommended for the two individual power zones in each rack of the system. This provides for the highest level of redundancy and system availability. If independent AC power is not available, there is a higher risk of data unavailability should a power failure occur, including individual phase loss occurring in both power zones.
Before connecting external AC power to storage bays, verify that the bays have been placed in their final position as explained in the installation guide.
Figure 27. Two independent customer-supplied PDUs
74 Best Practices for AC Power Connections
Selecting the proper AC power connection procedure The Dell Customer Engineer must select the proper AC power connection procedure.
The following table summarizes the three possible scenarios to connect customer AC power to the storage array. Select the procedure that matches the customer's situation.
