Replacing the Power Management/Interconnect Board
The replacement procedure is the same for the rack-mount and the pedestal HP NetServers once you gain
access to the Power Management/Interconnection board.
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 Power
Management/Interconnection board.
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.
