Installation Problems; Troubleshooting External Connections - QUANTA QSSC-980 User Manual

If you recently installed new software or new device drivers:
Try booting into Safe Mode and uninstall the new software or driver. If you can now boot normally, there may be
a compatibility issue between the new software or driver and some component in your system. Contact the soft-
ware manufacturer for assistance.
BIOS Changes
Changes to some advanced BIOS settings (such as those found in the Advanced Menu on page 34) can cause boot
issues. Changes to Advanced BIOS settings should only be made by experienced users.
If the BIOS Setup Utility is accessible by pressing F2 during boot, reset the BIOS to factory defaults by pressing
F9. Save and exit the BIOS Setup (see BIOS Setup Options at Boot on page 30 for more details).
If you cannot access the BIOS Setup Utility, clear the CMOS by performing the following steps:
1. Power down the server. Do not unplug the power cord.
2. Open the server chassis (see Removing the Chassis Cover on page 12).
3. Move jumper (J1C3) from the default operation position, covering pins 1 and 2, to the reset / clear
CMOS, covering pins 2 and 3.
4. Remove AC power.
5. Wait 5 seconds.
6. Move the jumper back to default position, covering pins 1 and 2.
7. Close the server chassis and power up the server.
The CMOS is now cleared and can be reset by going into BIOS setup.
Viewing System Event Logs for investigation
If the front panel LED blinks for 30 to 60 seconds upon applying AC power to the power supply, the baseboard
management controller (BMC) is initializing. If not, then the BMC is not functioning. If the BMC is working, try
to gather system event log (SEL) information for investigation.

Installation Problems

Perform the following checks if you are troubleshooting an installation problem:
Check all cable and power connections (including all rack cable connections).
Unplug the power cord, and wait one minute. Then reconnect the power cord and try again.
If the network is reporting an error, see if the server has enough memory and disk space available.
Remove all added options, one at a time, and try to power up the system. If after removing an option the
server works, you may find that it is a problem with the option or a configuration problem between the
option and the server. Contact the option vendor for assistance.
If the system doesn't power on, check the LED display. If the power LED is not on, you may not be re-
ceiving AC power. Check the AC power cord to make sure that it is securely connected.

Troubleshooting External Connections

Loose or improperly connected cables are the most likely source of problems for the system, monitor, and other
peripherals (such as a printer, keyboard, mouse, or other external device). Ensure that all external cables are se-
curely attached to the external connectors on your system. See QSSC-980 2U I/O Ports on page 6 for the back
panel connectors on your system.
Why can't the mouse synchronize in O.S. RHEL 3.0?
PS2 mice do not work under the RHEL 3.0 OS; the command "XSET" will fail. Replace the PS2 mouse with a
USB mouse.
