Troubleshooting general problems

Resolving common problems

Common problem guideline
System cannot power on
1.
Be sure that all power and I/O cords are securely connected
o
Verify that the the system board is powered up
o
Configure the server with the minimum components (one CPU, the least amount of memory, and
o
connect only the display monitor and keyboard). Connect directly to the system board jumper to
determine if the server now starts normally
Check the power. Remove all of the the power cables. Connect the green cable and the black
o
cable on the PSU power to check the result
If problems continue to occur, remove and reinstall each device, checking the connectors and
o
sockets for bent pins or other damage
System frequently reboots
2.
There are generally three factors that might cause the system to reboot:
Breakdown of power
o
Supply power to the server from an available power source
Problems with memory
o
Check the event log or memory configuration from the BIOS to determine if there is a problem
with the memory which requires replacing the memory. Check the display to determine if the
memory error was detected during POST. If the event log shows that a memory error caused the
memory problem, re-seat all of the memory by removing and re-installing all of the memory
modules. If reseating the memory modules does not resolve the memory/reboot problem, replace
the memory.
Problems with the software
o
Update the software or re-install the system
System stopped issue
3.
Track the reasons the system stopped from the software and hardware, respectively.
Software tracking: Check the system event log to identify and locate the problem.
o
Hardware tracking: The power supply is not sufficient; HDD/SSD has some problem (scan the
o
surface of them to check). Addon cards might also cause the system to halt (for example,
SCSI/RAID cards or other PCI facilities).
Pay attention to any possible reasons any of the hardware components might have caused the system
to stop, even if the problem has been resolved. Observe the server to confirm that the system stop
issue has whether it has been thoroughly resolved.
Failure to recognize the HDD during system installion
4.
Determine if the HDDs were installed in the HDD carriers
o
Determine if the SAS/SATA cables are correctly connected
o
Check the HDD LED indicators to determine if the drives are receiving power
o
