2-24 General Description

LEDs

This section describes indications and meanings of the LEDs on NEC Express5800/ft series.

See “NAMES AND FUNCTIONS OF COMPONENTS” (page 2-14) for the locations of each LED.

POWER LED

The POWER switch of the PCI module also functions as a POWER LED. When power is supplied to the modules, POWER LED on the primary side will illuminate (the switch also works on the primary side alone).

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:

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.

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.
