Chapter 7 Replacing Parts

Replacing the Power Supply

Replace a failed power supply or install a redundant power supply in the HP Server. Only one power supply

(425 Watt) is required for the HP Server. If power supply backup or redundancy is required, then an additional

power supply may be installed in slot #2.

If there is only one power supply installed, then the system will go down or fail to boot when the power supply

fails. The status LED on the defective supply will be off (dark).

If two power supplies are installed and one supply fails, the other supply will continue to operate and a front

panel LED should turn red to indicate there is a problem. The status LED on the defective power supply will be

off (dark). When power is applied to the system verify that the status LEDs for both supplies glows green.

Removing the Power Supply

1. Locate the desired power supply for removal. Refer to Figure 7-6 for location of power supply status LEDs.

Figure 7-6. Power Supply Rear Panel

WARNING If a power supply bay is not in use, be sure to keep the cover on it. If you do not, system

ventilation and EMI (electro-magnetic interference) suppression may be affected.

Always insert a power supply filler panel into an empty power supply bay. Operating

with an empty bay could cause thermal damage to the server.

CAUTION Gently insert power supply into the bay to avoid causing damage to the connector (DO

NOT SLAM).

NOTE If the HP Server is powered on (Power LED on front is green) and the status LED for one

of the seated power supplies is off, the supply has failed. However, when the HP Server is

in standby (plugged in but not powered-down), the power supply status LEDs will be off

(dark).
