Power Distribution-Modular Pdus - HP 6400/8400 User Manual

Power distribution–Modular PDUs
NOTE: This section describes the most common power distribution system for EVA6400/8400s.
For information about other options, see the HP power distribution units website:

AC power is distributed to the rack through a dual Power Distribution Unit (PDU) assembly mounted
at the bottom rear of the rack. The characteristics of the fully-redundant rack power configuration
are as follows:
Each PDU is connected to a separate circuit breaker-protected, 30-A AC site power source
(100–127 VAC or 220–240 VAC ±10%, 50 or 60-Hz, ±5%). The following figures illustrate
the most common compatible 60-Hz and 50-Hz wall receptacles.
NEMA L6-30R receptacle, 3-wire, 30-A, 60-Hz
IEC 309 receptacle, 3-wire, 30-A, 50-Hz
The standard power configuration for any Enterprise Virtual Array rack is the fully redundant
configuration. Implementing this configuration requires:
Two separate circuit breaker-protected, 30-A site power sources with a compatible wall
◦
receptacle.
One dual PDU assembly. Each PDU connects to a different wall receptacle.
◦
◦ Four to eight (depending on the rack) Power Distribution Modules (PDM) per rack. PDMs
are split evenly on both sides of the rack. Each set of PDMs connects to a different PDU.

◦ The drive enclosure power supplies on the left (PS 1) connect to the PDMs on the left with
a gray, 66 cm (26 in) power cord.
The drive enclosure power supplies on the right (PS 2) connect to the PDMs on the right
◦
with a black, 66 cm (26 in) power cord.
Each controller has a left and right power supply. The left power supplies of each should
◦
be connected to the left PDMs and the right power supplies should be connected to the
right PDMs.
