Replacing the System Board

The procedure is the same for the rack-mount and the pedestal HP NetServers once you gain access to the system board assembly.

1.Log off all users and gracefully shut down the network operating system according to directions in your NOS documentation.

2.Power down the HP NetServer.

3.Disconnect the power cords and cables, and if necessary, label each one to support re- assembly.

CAUTION The power supplies will continue to provide standby current to the NetServer until the power is disconnected.

4. For both rack-mounted and pedestal models, gain access to the system board assembly.

NOTE	In the rack-mounted version, this assembly is under the right side lower cover, in the
	pedestal version, it is under the top right cover.

WARNING Always disconnect the power cords before removing the covers, to avoid exposure to high energy levels that may cause burns when parts are short-circuited by metal objects such as tools or jewelry. Disconnect any telephone cables to avoid exposure to shock hazard from telephone ringing voltages.

5. Access the system board assembly.
