BMC Status LED
The BMC Status LED indicates the status of the Baseboard Management Controller (BMC)
installed on NEC Express5800/ft series.
The LED stays green while the server is running normally. If the LED is not green, there is
something wrong with the server.
The table below shows indications of the BMC Status LED and their meanings.
TIPS:
When you want to restart the server, perform a shutdown if the OS allows you to
shut down the system. If not, perform a reset or forced shutdown, or you can restart the
server by unplug and plugging the power cord.
