General System Problems

No lights are on and no error message appears.

If the server does not work (no lights are on) and no error message appears, check the following:

1.Make sure that all cables and power cords are plugged into their proper receptacles.

2.Make sure that the AC outlet is working. If the server is plugged into a switched multiple-outlet box, make sure that the switch on the outlet box is turned on.

3.Make sure that the server is turned on (the power-on light should be green and the fans should be on).

4.Turn the server off, wait at least twenty seconds, then turn the server back on to see if the failure can be cleared.

5.Make sure that all boards are installed properly and the processor module or modules are installed in the correct slot. They must be seated firmly in their slots and any cables must be connected firmly.

6.If your server stopped working after you installed a new board, remove the board and turn on the server. If your server now works, determine how to set the jumpers and switches on the board if there are any. If the new board is preventing the server from powering on, it's apt to have a serious electrical problem.

7.If your server still does not work, remove all boards and options that you have installed (do not remove the flexible or hard disk drives) and turn on the server.

8.Add the boards and options one at a time to determine which one is causing the problem.

9.If you have added any memory, make sure that the DIMM modules are seated properly in the board.

Power goes off on the server and doesn't come back on

When certain critical conditions exist, the server shuts down all power.

NOTE	It is a good idea to run the Event Log Display Utility on the HP NetServer Navigator
	CD-ROM as part of regular maintenance procedures so that you can check to see if
	any problems have been logged to the file. Also, this file needs to be purged at
	times since the error log can eventually fill up. Errors are time stamped with either a
	Real-Time Clock (default) or the POST Capture time stamp. See the HP NetServer
	Navigator CD-ROM, NetServer Utilities menu, for additional information on this
	feature.

The critical conditions that may shut down the server are:

•critical temperature fluctuations or changes
