Replacing the Fan Assembly
Use this topic to replace the Fan Module or the entire Fan Assembly. The three fans in the HP NetServer (LC
2000/LC 2000r) are in a single replaceable module enclosed in the fan tray. Do not hesitate to replace the
Fan Module when the system indicates slow or failing fans.
1. Log off all users and if necessary back-up files.
2. Follow instructions in your network operating system (NOS) documentation to gracefully shut
down all networking software and applications.
3. Press the power switch on the HP NetServer's control panel when prompted by the operating
system.
4. Disconnect the power cables.
WARNING The power supplies will continue to provide standby current to the NetServer until
the power cable is disconnected.
5. If you have a rack-mounted LC 2000r, 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.
6. Remove the top cover (rack-mount orientation) or the side cover (pedestal version). See
Remove and Replace Covers.
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.
7. Loosen the thumbscrew (it may require the T-15 driver) holding the fan module to the fan tray.
8. Lift the fan module up and out of the chassis.
