General Netserver Problems
No lights are on and no error message appears
If the Netserver does not work (no lights are on, including backlighting on models with LCDs) and no error
message appears, check the following:
1. Verify that power is good and available
2. Make sure that the Netserver is turned on (the power-on light should be green and the fans
should be on).
3. Turn the Netserver off and unplug the power cords. Wait 30 seconds and plug the power cords
in and turn the Netserver on. Verify the failure.
4. Verify all boards are installed properly and seated firmly in the slots with cables firmly
connected.
5. If the Netserver stopped working after you installed a new accessory, remove the accessory
and turn on the server. If the Netserver now works, go to step 8.
6. If the Netserver still does not work, remove all accessory that you have installed (do not remove
the flexible or hard disk drives) and turn on the server.
7. If the Netserver now works, turn off the Netserver; add one accessory at a time to determine
which one is causing the problem. Turn on the Netserver after installing each board or option.
When the problem returns, the last board or option installed is defective.
8. If you have added any memory, make sure that the modules are seated properly on the
processor board.
The application or operating system is not responding properly
1. In Netserver models with accessible cache feature, determine if the memory cache feature is
turned on or off.
Memory cache may need to be turned off for some older software. It may also need to be turned
off for those accessory boards that have on-board firmware, and for those boards that use
memory-mapped I/O.
2. If necessary, turn off the memory cache feature. Check the state of memory cache and, if
necessary, disable it:
a. Push
[F2]
during the boot process
b. Go to configuration and turn off Memory Caching
The Netserver stops working (hangs)
Typically, if the Netserver hangs before the end of the
POST
completes, the problem is probably a hardware
failure. If the Netserver hangs after the
POST
completes, the problem is probably due to an incorrectly
configured or corrupt driver, operating system, or application program, or a media (disk drive) error.
