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
on page 51 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 EMC 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.
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.
