Power Redundancy Considerations

If available for your server, power redundancy protects your server from power
failures caused by one of the following:
•
Power failure in one of the two AC circuits providing power to the server
•
Accidentally unplugging one of the power cords providing power to the server
•
Failure of one power supply (or SPM, if applicable to your server)
IMPORTANT: The power redundancy described in this section is not the same as protection
provided by a UPS. In the event of a catastrophic power failure affecting each power cord
providing power to the server, the server loses power and shuts down. To provide complete
power protection, HP recommends installing a suitable UPS.
Refer to your server-specific user documentation to determine what power
redundancy requirements are necessary for your server.

Preventing Grounding Problems

For proper operation and safety, the server must be properly grounded.
Refer to your server-specific user documentation for information about properly
grounding your server.

Preventing Temperature Problems

For continued safe and reliable operation of the equipment, install the server in a
well-ventilated, climate-controlled environment.
The maximum recommended ambient operating temperature (TMRA) for most
server products is 35°C (95°F). The temperature in the room where the rack is
located should not exceed 35°C (95°F).
The operating temperature inside the rack is always higher than the room temperature
and is dependent on the configuration of equipment in your rack. The TMRA for
each piece of equipment should be checked before installation.
