HP has the broadest, most robust server and storage line up in the industry, providing exactly the right fit
for every need. Refer to the Storage Server matrix found in the introductory section of Chapter 4 of this
configuration guide to see a matrix that highlights which storage device, server and operating system is
interoperable.

The HP 9000 rp7440 Server comes with two power supplies that provided dual grid (2N) protection. The
hot swap design allows for the replacement of a failed power supply without interrupting server
operation. All four power cords must be utilized to fully enable power supply hot swap. HP 9000
rp7410/rp7420/rx7620 DC power supplies can be carried forward to the HP 9000 rp7440 server.

PCI power supply is now a redundant N+1 design. One PCI power supply failure will not affect the I/O
bay since the remaining PCI power supply will power both I/O bays (this is an upgrade from the sx1000
based systems). PCI power supplies are hot swap capable (this is an upgrade from the sx1000 based
systems). HP 9000 rp7410/rp7420/rx7620 PCI Power Supplies cannot be carried forward to the HP
9000 rp7440 server.

The HP 9000 rp7440 Server contains four C20 power receptacle ports located at the bottom rear
bulkhead. A minimum of two power cords must be used to maintain normal operation of the HP 9000
rp7440 Server. A second set of two cords can be added to improve system availability by protecting, for
example, against power grid failures, accidentally tripped circuit breakers, or a failed power supply. The
HP 9000 rp7440 Server hardware is capable of receiving AC input from two different AC power
sources. The objective is to maintain full equipment functionality when operating from power source A
and power source B or A alone or B alone. This capability is called "fault tolerant power compliance."
Although many HP 9000 rp7440 Server configurations can be sufficiently powered from a single 16 /20
amp branch circuit, the optimum configuration is to use one 16 amp (minimum) branch circuit per
power cord. Due to the variety of 16/20 plugs used throughout the world, the HP 9000 rp7440 Server
Ordering Guide offers a choice of plug options.
The drawing below represents the power receptacle ports on the HP 9000 rp7440 Server. If only two
power cords are used, they must be plugged into either A0 and B0, or A1 and B1. Following this rule
will ensure that both power supplies are being used under normal conditions.
