Configuration

Power Distribution Units

60 amp Power Distribution Unit-

AF916A (NA/JPN) and AF917A (International)-supported in 10K G2 rack

E7683A (US) and E7684A (International)-supported in Rack System E

Customers who prefer the fewest higher amperage connections from their AC line current source to the

HP 9000 rp7440 Server can use the 60 amp power distribution unit (PDU). The AF916A and AF917A

PDUs contain 12 C19 outlets. The E7683A and E7684A PDUs contain 8 C19 outlets. For more details

on PDUs, please see PDU sales collateral. This PDU is sold separately and can be ordered with any HP

server solution.

The maximum amperage is 60 amps through the entire PDU and 20 amps per breaker. Both limits must

be met. Each 60 amp PDU can support up to four HP 9000 rp7440 servers if the PDU is not mounted in

the same rack. Up to three HP 9000 rp7440 servers can be supported if the PDU is mounted within the

same rack

For redundant power inputs, the second set of cords is added. If the second PDU is plugged into a

second grid this configuration provides protection against:

Losing power from a single power grid

Accidental tripping of one or two circuit breakers

Accidental disconnect of a single PDU power cord

Accidental disconnect of up to four (two from each system) system power cords

30 amp Power Distribution Unit-

252663 D74 (NA/JPN) and 252663 B33 (International)-supported for 10K G2 rack

E7681A (North America/JPN) and E7682A (International)-supported with Rack System E

A 30 amp Power Distribution Unit (PDU) is also supported with HP 9000 rp7440 Server. Rack

configurations consisting of peripherals and only one HP 9000 rp7440 Server will likely be best

supported with the 30 amp PDU. This PDU is sold separately and can be ordered with any HP server

solution.

Unlike the 60 amp PDU, each 30 amp PDU can only support one HP 9000 rp7440 Server. The

following configuration guidelines apply when using the 30 amp PDU:

A0 and A1 or B0 and B1 cords should never be plugged into the same PDU

Use two 30 amp PDUs to achieve input power redundancy (plugging A0/A1 and B0/B1 into

separate PDUs).

Ordering tools will not force the purchase of a second PDU for input power redundancy. A second

PDU must be manually selected if redundant input power is desired.
