60 amp Power Distribution Unit-
AF916A - supported in 10KG2 rack
E7683A - supported in Rack System E
Customers who prefer the fewest higher amperage connections from their ac line current source
to the HP 9000 rp7420 Server can use the 60 amp power distribution unit (PDU). This PDU is sold
separately and can be ordered with any HP server solution.
Each 60 amp PDU can support up to two HP 9000 rp7420 servers if the PDU is not mounted in
the same rack. Up to three HP 9000 rp7420 servers can be supported if the PDU is mounted
within the same rack.
Configuration Example for Using the 60 amp Power Distribution Unit
In this case there are two HP 9000 rp7420 Servers (average configurations drawing ~5 amps
each) and two 60 amp PDUs configured with redundant power. The solid line cords represent the
primary power connections needed for normal operation. In this example, cords from each server
are plugged into a separate branch circuits. However, it is acceptable for each server to plug both
grid A (A0 and A1) cords into one branch circuit and both grid B cords (B0 and B1) into a 2nd
branch circuit. The remaining PDU outlets can be used to power other servers/components as
long as specs per PDU rating is not exceeded.
For redundant power inputs, the second set of cords (dotted line) 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 - supported with 10K G2 rack
E7681A - supported with Rack System E
A 30 amp Power Distribution Unit (PDU) is also supported with HP Integrity rx7620. Rack
configurations consisting of peripherals and only one HP 9000 rp7420 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 Integrity rx7620. 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.
