SCSI Device Does Not Work
If error messages display on the monitor indicating a failure of a SCSI hard disk or tape backup device,
perform these checks:
1. Verify the power cable is securely connected to the drive, and the flat cable is securely
connected to the drive and to the SCSI connector on the system board.
2. Verify all SCSI devices have unique IDs.
3. Ensure your SCSI device is not terminated.
4. Ensure connector pins are not displaced or distorted.
Replacing a Battery
If your HP Netserver repeatedly loses its configuration or the processor clock stops, you should replace the
battery.
WARNING
There is a danger of explosion if the battery is incorrectly installed. For your safety,
never attempt to recharge, disassemble, or burn the old battery. Replace only with
the same or equivalent type recommended by the manufacturer. Dispose of used
batteries according to the manufacturer's instructions.
1. Power-down the HP Netserver and unplug power cord.
2. Remove the Netserver cover and the cooling duct/cover.
3. If the chassis is out of the rack, lay it on a flat surface with the system board components facing
up.
4. If necessary remove the PCI riser board, which may prevent access to the battery.
5. Insert a small flatblade screwdriver or similar tool between the battery and spring latch.
6. Push the spring latch away from battery to release the battery.
The spring contacts beneath the battery cause it to pop up allowing you to grasp the battery.
7. Remove the existing battery.
