Chapter 6 Replacing Parts
90
Use this topic to remove and replace a power supply in the HP NetServer. Only one power supply (350 Watt)
is required for either model of the HP NetServer, LC 2000 or LC 2000r. 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 the status LEDs for both supplies glows green.
CAUTION 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.
1. Locate the desired power supply for removal.
Refer to the figure for location of power supply status LED.
NOTE If the HP NetServer is powered on (Power LED on front is green) and the status LED
for one of the seated supplies is off, the supply has failed. However, when the
NetServer is in standby (plugged in but powered-down), the power supply status
LEDs will be Off (dark).
