the HP StorageWorks Enterprise Virtual Array Hardware Configuration Guide.
Power distribution
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
(220–240 VAC ±10%, 50 or 60 Hz, ±5%). Figure 49 illustrates the compatible 60-Hz and
50-Hz wall receptacles.

• 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 (see Figure 49 ).
• One dual PDU assembly. Each PDU connects to a different wall receptacle.
• Eight Power Distribution Modules (PDM) per rack. Four PDMs mount vertically on each side of
the rack. Each set of four 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.
• The upper controller connects to a PDM on the left with a gray, 152 cm (60 in) power cord.
• The lower controller connects to a PDM on the right with a black, 66 cm (26 in) power cord.
NOTE:
Drive enclosures, when purchased separately, include one 202 cm (80 in) black cable and one 202
cm (80 in) gray cable.
The configuration provides complete power redundancy and eliminates all single points of failure for
both the AC and DC power distribution.
PDUs
Each Enterprise Virtual Array rack has either a 50- or 60-Hz, dual PDU mounted at the bottom rear of the
rack. The 30–56205–03/30–56205–04 PDU placement is side-by-side. The 228481–002/228481–003
PDU placement is back-to-back, plugs facing out.
