If an overload triggers the power supply overload protection, the system is immediately powered

off. To reset the power supply unit:

1. Disconnect the power cord.

2. Determine what caused the overload by contacting an HP support representative.

3. Reconnect the power cord.

4. Reboot the system.

NOTE: If an overload occurs twice, an undetected short circuit exists.

When you use the front panel power button to turn off the server, power consumption falls below

the low power consumption, but does not reach zero. To reach zero power consumption in "off"

mode, either unplug the server or use a power block with a switch.

Power consumption and cooling

The power consumptions listed in Table 5 (page 17) are valid for a standard configuration as

shipped.

All information in this section is based on primary power consumptions with one power supply

installed.

Server physical and environmental specifications

Operating temperature and humidity ranges might vary, depending on the installed mass storage

devices. High humidity levels can cause improper disk operation. Low humidity levels can aggravate

static electricity issues and cause excessive wear of the disk surface.

NOTE: De-rate maximum dry bulb temperature 1°/300 m (1000 ft) above 900 m (3000 ft).
