6: Basic Troubleshooting and Chassis Service
System Powers Up But Will Not Boot
If the system powers up but will not boot the Operating System, check the following:
• Check the system order document(s) - the C2110G-RP5 server may have been ordered with
no operating system. If so, check with your system administrator for OS loading
information.
• Check the system disk (drive 0) for drive activity and confirm that it is firmly seated in the
disk bay. A red light on the front of the disk indicates a functional error. Check with your
service provider or local system administrator.
No Video After System Power Up
If the system powers up and appears to be booting normally but no video is present, try the
following basic solutions:
• Confirm your monitor is plugged in and switched on.
• Check all video cables and ensure they are properly connected.
• Listen for a BIOS “beep code” error message - one long beep plus 8 short beeps indicates a
video error. This beep code message could indicate a video memory error or other video
malfunction; contact your service provider.
• If using an optional PCIe video card check the back of the card for LED activity or a fault
indicator. Try opening the system, reseating the PCIe card and rebooting; see the section
“Install/Replace a PCIe Expansion Card” on page 56 .
If you cannot get a video signal after trying basic solutions contact your support provider.
Memory Errors
If your system experiences memory related errors, try these basic troubleshooting steps to resolve
or better identify the problem:
• Confirm that the power supply LED is not indicating an error.
• Listen for memory error beep codes - five short beeps followed by one long beep is a BIOS
signal that no system memory has been detected - See
Appendix A, “BIOS Error Codes” .
• Shut the system down, remove the covers over the serverboard and make sure that all the
DIMM modules are properly and fully installed.
