System Requirements Summary
This appendix summarizes the requirements that must be considered in preparing the site for
the HP Integrity rx7620 Server.
Power Consumption and Air Conditioning
To determine the power consumed and the air conditioning required, follow the guidelines in
Table B-5.
NOTE: When determining power requirements, consider any peripheral equipment that will
be installed during initial installation or as a later update. To determine the power and air
conditioning that is required to support these devices, see the applicable documentation for such
devices.
Maximum power is the sum of the worst case power consumption of every subsystem in the box
and should be used to size worst case power consumption. Typical power consumption numbers
are what HP engineers have measured when running power-intensive applications. These are
generally lower than maximum power numbers because it is uncommon for all of the subsystems
in the box to simultaneously draw maximum power for long durations.
Weight
To determine overall weight, follow the examples in Table B-6, then complete the entries in
Table B-7.
