If the System Powers On, but Fails POST (Power-On Self Test)
Do one of the following:
• If the system gives a series of beeps, this indicates a system error. Contact
HP or your reseller.
• If the system fails POST and an error message displays on the screen, see
the section "Error Messages." If the suggested solutions do not solve your
problem, contact HP or your reseller.
If the System Passes POST (Power-On Self Test)
but Does Not Function
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 HP or your reseller.
If there is no error message, follow these steps:
1. Check to ensure that the NetServer is configured correctly in the Setup
Utility.
2. If the server still does not work, turn it off and remove all external
peripherals, except the monitor and keyboard. Test to see if the server now
works.
3. If the server still does not 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. Remove the
NetServer cover.
b. Check that all accessory boards are firmly seated in their slots.
c. Ensure that all disk drive power and data cables are securely and
properly connected. Verify the mass storage configuration with the
cabling and switch diagrams shown on the HP NetServer Reference
Board, located in a plastic pouch on the interior of the NetServer
covers.
d. Verify that the DIMMs are firmly seated on the System Board. Verify
that added DIMMs are HP DIMMs.
e. Replace the NetServer covers, and lock the system.
f. Replace all power cords and power cables.
g. Turn on the monitor.
