Third party racks with vertical PDUs — RPQ Required
Each system bay is powered by two redundant power distribution units (PDUs), one
PDU for each power zone. Rather than use the standard EMC horizontal PDU, the
customer can use vertical PDUs via RPQ. The general requirements for third party
racks with rear-facing or inward-facing PDUs are listed below.

General requirements for vertical PDUs within third party racks
In addition to meeting standard VMAX array power requirements, vertical PDUs should
abide by the following:
l
Both PDUs support AC-line input connectivity and provide outlets for every
component in the bay.
l
The PDU must be available in the wiring configuration that matches the customer
power supply.
Options include:
n
Single-phase
n
Three-phase Delta
n
Three-phase Wye
l
Each PDU should meet the following requirements:
n
At a minimum, a total of 24 power outlets must be provided.
The outlets are divided into six banks with each bank consisting of four IEC
60320 C13 individual AC outlets.
n
Each bank of outlets is connected to individual branch circuits that are
protected by a single two pole 20 Amp circuit breaker.
n
The PDU capacity should exceed the power requirements shown in the Power
Calculator for the specific max configuration.
n
Single PDU mounted per side per
on page 100 and
on page
102.
If the customer requires power to be supplied from overhead, EMC recommends one
of the following:
l
Option 1: Replace the rear top cover of the bay with the ceiling routing top cover,
described in
on page 106, which allows the power cables
inside the machine to be routed out through the top.
l
Option 2: "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, minimize cable
congestion, and provide access to components within the system.
