Reset button:
Press this button to reset the server and run the power-on self-test (POST). You might
have to use a pen or the end of a straightened paper clip to press the button. The Reset button is in
the lower-right corner of the light path diagnostics panel.
The system service label inside the server cover provides an overview of internal components that
correspond to the LEDs on the light path diagnostics panel. This information and the information in
“Light path diagnostics LEDs” on page 166 can often provide enough information to diagnose the error.
3. Remove the server cover and look inside the server for lit LEDs. Certain components inside the server
have LEDs that are lit to indicate the location of a problem.
Note:
You do not have to remove the server cover to view the LEDs on hard disk drives and power
supplies.
The following illustration shows the LEDs and connectors on the system board.
