8-4 Troubleshooting
STATUS Lamp
The STATUS lamp stays lit in green when the server is in successful operation. When the
STATUS lamp is unlit or lit/flashing in amber, it indicates that the server has failed.
The following table lists indications of the STATUS lamp, descriptions, and actions to take.
NOTES:
If the server has the NEC ESMPRO or Off-line Maintenance Utility
installed, you can view the error log to identify the cause of a
trouble.
To cycle power to the server, shut down the server from the OS and
reboot it, if available. If the shutdown from the OS is not available,
reset or execute the forced shut down or disconnect and connect the
power cord to reboot the server.
