System Maintenance
NOTE:
If you are using a third-party video controller card and the onboard video controller (if
applicable) was disabled, remove this controller card, connect the cable to the onboard video controller
then clear the CMOS. This re-enables the onboard video. For instructions on clearing CMOS, go to
Chapter 5.
17. Disconnect the power and SCSI connections from tape drives and hard drives.
18. Disconnect the IDE and flexible disk cables.
19. Plug the server into a power source and turn on the server.
If video still does not return, turn the server back off and unplug the power cord.
20. Reseat all major boards and power supplies.
21. Double check the cables that connect the power supplies to the power management board,
if one exists.
22. Reinstall the remaining components one at a time until video returns.
One of the removed components may have been causing the no video problem. After all
the components are reinstalled, reset the server’s BIOS configuration switch back to the
appropriate setting.
