server. This number will NEVER be exceeded by a functioning server for any combination of
hardware and software under any conditions.
Marked Electrical Power:
(Input power at the ac input expressed as Volt-Amps.)
The server Marked Electrical Power is the rating given on the chassis label and represents the
input power required for facility ac power planning and wiring requirements. This number
represents the expected maximum power consumption for the server based on the power rating
of the bulk power supplies. This number can safely be used to size ac circuits and breakers for
the system under all conditions.
Typical Maximum Power:
or User Expected Maximum Power, "Typical Configuration"
(Expressed as Volt-Amps.)
The measured maximum worst case power consumption. This number represents the larges
power consumption that HP engineers were able to produce for the server with any combination
of hardware under laboratory conditions using aggressive software applications designed
specifically to work the system at maximum load. This number can safely be used to compute
thermal loads and power consumption for the system under all conditions.
For further power consumption details, see the HP Integrity rx7640 Installation manual.

Power Distribution
Units
60-amp Power Distribution Unit-
AF916A (NA/JPN) and AF917A (International) - supported in 10KG2 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 Integrity rx7640 Server can use the 60 amp power distribution unit (PDU). The
AF916A & AF917A PDU's contain 12 C19 outlets. The E7683A & E7684A PDU's contain 8 C19
outlets. For more details on PDU's, 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. If each 60 amp PDU can support up to four HP Integrity rx7640 servers if
the PDU is not mounted in the same rack. Up to three HP Integrity rx7640 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:
