If an error message displays on the screen, read the error message text for actions
to take. If the actions do not solve your problem, contact your reseller.
If there is no error message, follow these steps:
1. Turn off the server and remove all external peripherals, except the
monitor and keyboard. Boot from an internal hard drive and see if the
server now works.
2. If the server still doesn't work, turn off the monitor, the server, and all
external devices, and check the internal hardware, as follows:
a. Unplug the power cord and all telephone cables.
b. Check that all accessory boards are firmly seated in their slots.
c. Verify that the DIMMs are firmly seated on the memory board. Verify
that added DIMMs are HP DIMMs
d. Ensure that all disk drive power and data cables are securely and
properly connected, both at the rear of each drive. Verify the mass
storage configuration with the cabling and switch diagrams
e. Replace the HP NetServer cover.
f. Replace all power cords and power cables.
g. Turn on the monitor.
h. Turn on the server at the control panel.

can create one by inserting the NetServer Navigator CD-ROM in a system
and selecting DiagTools from the HP NetServer Utilities menu.
