Removing the HP NetServer LH 3000 Bezel
Replacing the Bezel – Pedestal
1. Replace the bezel by placing the two tabs at the bottom of the bezel into the corresponding
slots on the chassis and snapping the bezel into position at the top of the chassis.
2. Lock the bezel, using the supplied key, and remove the key from the front of the NetServer.
Replacing the CD ROM Drive
Replace the CDOM drive only after you have verified that is failing with DiagTools. POST error codes
suggesting floppy disk drive problems are usually caused by problems on 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 side 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.
6. Remove the bezel. If necessary, temporarily remove the I/O fans.
7. Disconnect the signal cable (ribbon cable) and the power cable from the rear of the CD-ROM
drive.
