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 Technologies 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

Identify power requirements with site electrician.

Comments and/or Provide

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 Technologies Traffic Department arranges for delivery directly to the customer’s computer room. To ensure successful delivery of the system, Dell Technologies 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 Technologies 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.

Optical multimode cables

Radio frequency interference

Electro-magnetic fields, which include radio frequencies can interfere with the operation of electronic equipment. Dell

Technologies 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 Technologies 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 Technologies 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.

Power consumption and heat dissipation

Use the Dell Technologies 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.

Power values and heat dissipations shown at >35°C reflect the higher power levels associated with both the battery recharge cycle, and the initiation of high ambient temperature adaptive cooling algorithms. Values at <26°C are reflective of more steady state maximum values during normal operation.

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 35°C 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 20–80% non condensing, however, the recommended operating environment range is 40–55%. 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 Technologies 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 Technologies 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.

Shock and vibration

The following table provides the platform shock and vibration maximums and the transportation shock and vibration levels (in the vertical direction).

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.

NOTE: The previous information is provided on an “as is” basis and provides no representations, warranties, guarantees or obligations on the part of our company. This information does not modify the scope of any warranty set forth in the terms and conditions of the basic purchasing agreement between the customer and the manufacturer.

Remote support

Secure Remote Services is an IP-based, automated, connect home and remote support solution. Secure Remote Services is the preferred method of connectivity. Two connections with Secure Remote Services are recommended for connection to the redundant management module control station (MMCS).

Customers of Secure Remote Services must provide the following:

● An IP network with Internet connectivity.

● Capability to add Gateway Client servers and Policy Manager servers to the customer network.

● Network connectivity between the servers and Dell Technologies devices to be managed by Secure Remote Services.

● Internet connectivity to the Secure Remote Services infrastructure by using outbound ports.

● Network connectivity between Secure Remote Services Client(s) and Policy Manager.

Once installed, Secure Remote Services monitors the array and automatically notifies Dell Technologies Customer Service in the event of a problem. If an error is detected, a support professional utilizes the secure connection to establish a remote support session to diagnose, and if necessary, perform a repair.

Customer Service can use Secure Remote Services to:

● Perform downloads of updated software in lieu of a site visit.

● Deliver license entitlements directly to the array.

NOTE: Dell Technologies provides an optional modem that uses a regular telephone line or operates with a PBX. Dell

Technologies recommends using two connections to the redundant management module control station (MMCS).

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 Technologies and the customer,

Dell Technologies fully disclaims any and all liability for any damage or injury resulting from the customer’s 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 Technologies recommends the use of coverings, such as plywood, to protect floors during system roll.

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 manufacturer’s 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.

System bay layouts

The number of bays and the system layout depends on the array configuration, the customer requirements, and the space and organization of the customer data center.

Arrays can be placed in the following layouts:

● Adjacent — bays are positioned side-by-side.

● Dispersed — dispersed layouts are provided with longer MIBE optical and Ethernet cable bundles that allow 82 ft (25 m) of separation between System Bay 1 and System Bay 2.

Dispersed system bays require dispersed cable and optics kits. When systems are ordered as dispersed, the dispersed bay is shipped with two side skins installed.

Adjacent layouts, PowerMax 8000

PowerMax 8000 systems with adjacent layouts position System Bay 1 next to System Bay 2.

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 Technologies 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 Technologies recommends that the customer's electrician be present at installation time to work with the Dell Technologies 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 Technologies 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 customer‘s 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 customer’s 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.

An imbalance of AC input currents may exist on the three-phase power source feeding the array, depending on the configuration. The customer's electrician must be alerted to this possible condition to balance the phase-by-phase loading conditions within the customer's data center.

Power cords

Dell Technologies power cords connect each storage bay's PDU to the customer's power source. The power cords offer different interface connector options. The number of cords needed is determined by the number of bays in the array and the type of input power source used (single-phase or three-phase).

Single-phase

The following table describes the power cords for single-phase power transmission. Each power cord model contains two (2)

15FT (4.57M) cords.

Single-phase powered systems use a jumper, PN 038-004-186. See

PowerMax 2000 line cord and jumper configurations

on page 45 and

PowerMax 8000 line cord and jumper configurations

on page 48 for line cord and jumper configurations.

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 cabinet’s 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 Technologies 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 Technologies 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 Technologies 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.

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 Technologies array to stack from the bottom of the rack and customer equipment from the top of the rack.

○ A Dell Technologies 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 Technologies 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.

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 Technologies 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.

58 Third Party Racking Option for PowerMax 2000

PowerMax 2000 power consumption and outlet requirements

Power values are shown at >35°C to reflect the higher power levels associated with both the battery recharge cycle and the initiation of high ambient temperature adaptive cooling algorithms. Power consumption is listed as the combined value for zone

A and zone B outlets together.

NOTE: Engine power cables connect to each SPS, not to PDU outlets.

Third Party Racking Option for PowerMax

8000

The PowerMax 8000 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:

● To ensure integrity of cables and connections, do not move racks that are secured (bolted) together after installation.

● 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 mini-racks 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:

● National Electrical Manufacturers Association (NEMA) standard for 19-inch cabinets.

● Individual racks must be empty at the time of installation.

● Threaded hole racks are not supported.

● The cabinet must be in its final location with stabilizing (anti-tip) brackets installed.

● A separate rack that supports a minimum 1,300 lb/590 kg of equipment weight must be provided for each system bay.

NOTE: The customer must ensure floor load bearing requirements are met.

● Components and cables installed in customer racks must conform to these configuration rules:

○ The stack up must adhere to the standard configuration. Components and cables within a system bay can not be moved to available space in a different bay, or to a different location within the same bay.

○ The system must be properly positioned in accordance with physical placement rules.

● The internal depth with the front and rear doors closed must meet minimum requirements for either rear-facing or inwardfacing PDUs. This measurement is from the front surface of the NEMA rail to the rear door.

○ Rear-facing PDUs: Minimum 42" depth

○ Inward-facing PDUs: Minimum 44" depth

● Round or square channel openings must support M5 screws that secure rails and components. Clip nuts are provided as required.

● Non-dispersed rack-to-rack pass-through cable access at least 3 inches (7.6 cm) in diameter must be available via side panels or horizontal through openings.

● To ensure proper clearance and air flow to the array components, customer supplied front doors and standard bezels, if used, must include a minimum of 2.5 inch (6.35 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.

Third Party Racking Option for PowerMax 8000 63

○ Appropriate access for service personnel, with no items that prevent front or rear access to Dell Technologies components.

○ Exterior visibility of system LEDs.

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 Technologies 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 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 Technologies 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.

Procedure A, Task 3: Customer electrician

About this task

NOTE: This task is performed by the customer's electrician.

Steps

1. Working with the Dell Technologies Customer Engineer, turn ON all the relevant circuit breakers in customer-supplied PDU 2.

Verify that only power supply and/or SPS LEDs in power zone A are ON or flashing green in every bay in the array.

CAUTION: The bay is incorrectly wired if all (power zone A and B) power supply and/or SPS LEDs in a bay are

ON or flashing green. Check that the AC power to both storage bay power zones is not supplied by a single

PDU (customer-supplied PDU 2). The wiring must be corrected before moving on to the next step.

2. Turn OFF the relevant circuit breakers in customer-supplied PDU 2.

Verify that the power supply and/or SPS LEDs that turned green in the previous step changed from green to OFF and/or flashing yellow. The yellow SPS lights flash for a maximum of 5 minutes.

NOTE: Power supplies connected to an SPS continue to have green lights ON while the SPS yellow light continues to flash indicating the SPS is providing on-battery power.

3. Repeat step 1 and step 2 for power zone B and customer-supplied PDU 1.

4. Turn ON all the relevant circuit breakers in customer-supplied PDU 1 and customer-supplied PDU 2.

5. Label the PDUs as described in

Applying PDU labels on page 85.

Procedure C: Obtain customer verification

About this task

Perform this procedure if the three conditions listed below are true:

● The customer-supplied PDU source cables are already plugged into the storage bay PDU.

● You have no access to the area below the raised floor.

● The customer's electrician is not available at the installation site.

Steps

1. Have the customer verify that their electrician has complied with power specifications for voltage levels and redundancy.

If the customer cannot verify this, provide them with a copy of Procedure A. Inform the customer that their array may prematurely shut down in the event of a site power issue.

2. Record the customer-supplied PDU information (AC source voltage) as described in step 1 of Procedure A, Task 1: Customer electrician on page 77 and label the PDUs as described in

Applying PDU labels on page 85.

PDU labels

Before applying labels to the sidewalls of the cabinet, one of the following procedures must have been completed:

Procedure A: Working with the customer electrician onsite on page 76

Procedure B: Verify and connect

on page 84

Procedure C: Obtain customer verification

on page 85

3. For third-party racks, do one of the following:

● For three-phase power: Using plastic ties, attach the PDU connection tag to the main AC power cable connected to zone

A and B. Place the label close to the plug but on the side of the rack where it will not interfere with any rails.

● For single-phase power: Using plastic ties, attach the PDU connection tag to the P1 AC power cable connected to zone A and B. Place the label close to the plug but on the side of the rack where it will not interfere with any rails.
