HP 9000 rp7420 Server contains one removable media bay, which will support either a
DVD-ROM or DDS-4 DAT drive. Removable media drives are not hot-plug capable.
DVD-ROM drive provides enhanced features while preserving backward read compatibility
with CD-ROM. Data transfer rates of up to 6.75 MB/s are achieved with the DVD format; 4.8
MB/s can be achieved with the CD format.
DDS-4 drive has a maximum storage capacity of 40 GB with a peak transfer rate of 21.6
GB/hour compressed.

DC Power Supplies
The HP 9000 rp7420 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.
PCI Power Supplies: Each PCI power supply is dedicated to a single I/O bay. A PCI power supply
failure will affect the nPar utilizing that PCI supply and the associated I/O bay. All other nPars will
continue normal operation. PCI power supplies are not hot-swap capable.
AC Power
The HP 9000 rp7420 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 rp7420 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 rp7420 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 Integrity rx7620 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 rp7420
Server menu offers a choice of plug options.
