System Maintenance
10. If the error message
INVALID CONFIGURATION
displays, check the server’s video
configuration using the BIOS Setup Utility.
Make sure that other accessory boards do not use the same memory addresses as the
embedded video connector.
If after doing the steps above, the video problem still persists, follow the guidelines described
in the next section.
Basic Guidelines for Troubleshooting Video Issues
The guidelines below are arranged in such an order as to be followed progressively. The
server should not be re-populated with components until a video image is produced. And note
that:
•
•
For each step taken, be certain to unplug the power cord for 30–60 seconds prior to
powering the server back on.
For each power up attempt, allow at least 60 seconds for the server to produce a video
image.
1. Test the monitor on another machine to verify the monitor is not faulty.
2. Disconnect the server from any console switch box during troubleshooting.
3. Connect a known good monitor, keyboard, and mouse to the server.
4. Verify that the AC power source is good. If suspect, try another power source.
If there’s still no video image, proceed to the next step.
5. Perform steps 1 through 3 of the pre-installation instructions listed in Chapter 4.
6. Remove the left-side cover as described in Chapter 4.
7. Perform the pre-installation instructions listed in Chapter 4.
8. Locate the dip switch (SW1) on the mainboard.
Refer to Chapter 2 for a view of the mainboard layout.
9. Identify and toggle the SW1-1 of the dip switch to the
On
position to clear the CMOS
memory.
Quite often, just toggling the SW1-1 switch will restore video.
10. Switch SW1-1 back to its default
Off
position.
11. Check the processor speed switches to verify that they are set correctly.
12. Plug the server into a power source and turn on the server.
13. Verify that fans and hard drives are spinning up.
If there is still no video:
14. Repeat steps 4 through 5.
15. Remove and reseat the memory and take down to base memory.
16. Remove all PCI controller cards.
