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 H2106-G7 server may have been ordered with no
operating system. If so, check with your system administrator for OS loading information.
• Check the system disk 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.
• 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 PCI card and rebooting.
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.
• Shut the system down, remove the covers over the serverboard and make sure that all the
DIMM modules are properly and fully installed.
• You should be using registered ECC DDR3 memory. Also, it is recommended that you use
the same memory type and speed for all DIMMs in the system. See Chapter 5 for more
memory details.
• Check for bad DIMM modules or slots by swapping modules between slots and noting the
results.
Contact your administrator or support provider if the memory errors continue.
