If it is a hardware error, follow these steps:
1. Log users off the LAN and power down the server. Remove the
NetServer cover.
2. Simplify the HP NetServer configuration to the minimum required: a
monitor, one flexible and one hard disk drive and a keyboard. Remove
all third-party options, and reinstall one at a time, checking the system after
each installation.
3. Boot the system. If the system does not function, refer to the following
procedures. If you get an error message, see the section “Error Messages.”
If the System Will Not Power On
Follow these steps:
1. Check to ensure that all cables and power cords are firmly plugged into
their proper receptacles.
2. Check to ensure that all parts of the system are turned on and
properly adjusted.
3. If the server is plugged into a switched multiple-outlet box, make sure the
switch on the outlet box is turned on.
4. Plug a different electrical device (such as a printer) into the power outlet,
and turn it on.
