Replacing the Flexible Disk Drive
Replace the flexible disk drive only after you have verified that is failing with DiagTools. POST error codes
suggesting flexible disk drive problems are usually caused by problems on the system board.
NOTE You may run into a case where a flexible disk drive passes DiagTools but files
written to it will not be readable by other floppies to do mechanical misalignment.
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).
