Caution –
When you use the Power button to enter standby power mode, power is still
directed to the service processor board and power supply fans, indicated when the
Power/OK LED is flashing. To completely power off the server, you must disconnect the AC
power cords from the back panel of the server.
Remove the server cover, as required.
For instructions on removing the server cover, refer to the Sun Fire X4640 Server Service
Manual .
Inspect the internal status indicator LEDs, which can indicate component malfunction.
Note –
The server must be in standby power mode to view the internal LEDs.
For the LED locations and descriptions of their behavior, see “Troubleshooting DIMM
Problems” on page 15 .
Note –
You can hold down the Locate button on the server back panel or front panel for 5
seconds to initiate a “push-to-test” mode that illuminates all other LEDs both inside and
outside of the chassis for 15 seconds.
Verify that there are no loose or improperly seated components.
