Replacing the I/O Board
NOTE You may wish to use the Navigator CD to print or save configuration data stored on
the current system board (in NVRAM) before you swap out the System Board.
1. Log off all users. Back up files. Follow instructions in your network operating system (NOS)
documentation to gracefully shut down all networking software and applications.
2. Press the power switch on the HP NetServer's control panel when prompted by the operating
system.
3. Disconnect the power cables.
WARNING The power supplies will continue to provide standby current to the NetServer until
the power cable is disconnected.
4. If you have a rack-mounted LH 3000r, then consider removing the signal cables from the rear of
the enclosure before extending the enclosure on the slides (if you don't have a cable
management arm). If necessary, label the signal cables to support re-connecting them.
5. Remove the top cover (rack-mount orientation) or the left cover (pedestal version).
CAUTION Wear a wrist strap and use a static-dissipating work surface connected to the
chassis when handling components. Ensure that the metal of the wrist strap
contacts your skin.
