Action
Verify that the power cord is properly plugged in the power outlet.
Check if other equipment plugged in the same power outlet works.
Note: If the fans are turning, but the system emits no beeps, verify
that:
• The monitor is turned on.
• The power cord to the board (processor and main) is plugged
in correctly.
Identify the type of beeps that your system emitted: system board
beeps or RAID beeps.
• The system board beeps are usually short; their pattern is
identified in the 703t Server Maintenance and Diagnostics
guide (NN44200-702). The system board beeps are usually
not associated with information displayed on the screen. If the
system does not display information on the screen but emits
board beeps, then a main board condition is present.
•
The RAID beeps are high-pitched and long. The RAID beeps
emitted by the system during startup are associated with
messages indicating that a system is in a critical state.
Check the status LED at the front for a blinking or steady amber
light, which indicates that:
• A critical temperature or voltage fault has occurred.
• The CPU was not installed or is not functioning.
Check the beep codes provided in the 703t Server Maintenance
and Diagnostics guide to identify the failure, and then replace the
defective component or remedy the fault.
