service representative or authorised dealer for help.
Power Light Does Not Light
Check the following:
Is the system operating normally? If so, the power LED is probably defective or
the cable from the front panel to the server board is loose.
Are there other problems with the system? If so, check the items listed under
“System Cooling Fans Do Not Rotate Properly.”
If all items are correct and problems persist, contact your service representative or
authorised dealer for help.

POST emits a beep code, write down the beep code you hear. This information
is useful for your service representative.

display monitor or video controller may have failed. Contact your service
representative or authorised dealer for help.
