http://h18004.www1.hp.com/products/servers/proliantstorage/racks/index.html Power distribution units AC power is distributed to the rack through a dual Power Distribution Unit (PDU) assembly mounted at the bottom rear of the rack (modular PDU) or on the rack (monitored PDU). The modular PDU may be mounted back-to-back either vertically (AC receptacles facing down and circuit breaker switches facing up) or horizontally (AC receptacles facing front and circuit breaker switches facing rear). For information about PDU support with the P63x0/P65x0 EVA, see the HP P6300/P6500 Enterprise Virtual Arrays QuickSpecs. For details and specifications about specific PDU models, see the HP Power Distribution Units website: http://h18004.www1.hp.com/products/servers/proliantstorage/power-protection/pdu.html The standard power configuration for any HP 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 (PDMs) per rack. All PDMs are located (side by side in pairs) on the left side of the rack. Each set of PDMs connects to a different PDU. ◦ Eight PDMs for 42U, 47 U, and 42U 5642 racks ◦ Six PDMs for 36U racks ◦ Four PDMs for 22U racks • Each controller enclosure has two power supplies: ◦ Controller PS 1 connects to the left PDM in a PDM pair with a black, 66 cm (26 inch) power cord. ◦ Controller PS 2 connects to the right PDM in a PDM pair with a gray, 152 cm (60 inch) power cord. NOTE: Drive enclosures, when purchased separately, include one 50 cm black cable and one 50 cm gray cable. The configuration provides complete power redundancy and eliminates all single points of failure for both the AC and DC power distribution. PDU 1 PDU 1connects to AC PDM 1-1 to 1-4. A PDU 1failure: • Disables the power distribution circuit • Removes power from the left side of the PDM pairs • Disables drive enclosures PS 1 • Disables the controller PS 1 PDU 2 PDU 2connects to AC PDM 2-1 to 2-4.

The standard power configuration for any HP 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 (PDMs) per rack. All PDMs
are located (side by side in pairs) on the left side of the rack. Each set of PDMs connects to
a different PDU.
◦
Eight PDMs for 42U, 47 U, and 42U 5642 racks
◦
Six PDMs for 36U racks
◦
Four PDMs for 22U racks
•
Each controller enclosure has two power supplies:
Controller PS 1 connects to the left PDM in a PDM pair with a black, 66 cm (26 inch)
power cord.
◦
◦
Controller PS 2 connects to the right PDM in a PDM pair with a gray, 152 cm (60 inch)
power cord.
NOTE:
Drive enclosures, when purchased separately, include one 50 cm black cable and one
50 cm gray cable.
The configuration provides complete power redundancy and eliminates all single points of failure
for both the AC and DC power distribution.
PDU 1
PDU 1connects to AC PDM 1–1 to 1–4.
A PDU 1failure:
•
Disables the power distribution circuit
•
Removes power from the left side of the PDM pairs
•
Disables drive enclosures PS 1
•
Disables the controller PS 1
PDU 2
PDU 2connects to AC PDM 2-1 to 2–4.
