Status Lamp
The STATUS lamp is on (green) while the server is operating normally. (The rear panel
also has the STATUS lamp on it.) If the STATUS lamp is off or turns amber and flashes,
it indicates that the server is in abnormal state.
The table below explains the STATUS lamp indication, the meanings, and the
procedures.
Notes:
■
If NEC ESMPRO is installed, you can confirm the cause of a
failure by referring to the error log.
■
If shutdown processing can be performed through the oper-
ating system when you want to restart the system after turn-
ing the power off, restart the system by performing shutdown
processing. If shutdown processing cannot be performed,
restart the system by resetting, forcibly turning the power off,
or disconnecting and then connecting the power cord.
