NEC 320Lb-R manual PCI Module LEDs, BMC Status LED, LED indications Description Action

PCI Module LEDs

This section describes the LED indicators located in the PCI Module and will assist you in determining the appropriate action to take as the result of a specific LED indications. PCI Module LEDs include the Power LED, the BMC LED, the PCI Status LEDs 1 and 2 and the Disk Access LED.

POWER LED

The POWER switch of the primary PCI module also functions as a POWER LED. See Figure 1-4. When AC power is supplied to the modules, the POWER LED on the primary PCI module illuminates. The POWER switch on the secondary PCI module will be unlit and will not respond until a failure in the primary PCI module causes the secondary PCI module to assume primary functionality.

BMC Status LED

The BMC Status LED located on the front of the PCI module (see Figure 1-3) indicates the status of the Baseboard Management Controller (BMC).

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 1-1 shows the indications of the BMC Status LED and their meanings.

Tips:

!To determine the cause of trouble, use ESMPRO or the Off-line Maintenance Utility to view the error log.

!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.
