The following table describes each numbered LED in the preceding diagram:
Table. LED descriptions
LEDs Meaning
1 O/S disk drive B status LED
2 O/S disk drive A status LED
3 Power status LED
4 Server status LED
5 Fan 1 status LED
6 Fan 2 status LED
The following table describes the various power status LEDs.
Table. Power status LED (green)
LEDs Meaning
Green Normal operational mode of an active cluster node.
Slow flash (once every three seconds) The system has been shut down.
Medium flash (once every .8 seconds) The server is available to host file services but is not currently doing so. This also occurs if no EVS is configured, or if all EVSs are running on the other node in a cluster.
Fast flash (five flashes per second) The server is rebooting.
Off The server is not powered up.
The following table describes the various server status LEDs:
Table. Server status LED (amber)
LEDs Meaning
Amber Critical failure and the server is not operational.
Slow flash (once every three seconds) System shutdown has failed. Flashes once every three seconds.
Medium flash (once every .8 seconds) The server needs attention, and a non-critical failure has been detected, for example, a fan or power supply has failed. Flashes once every .8 seconds.
Off Normal operation.
The following table describes the varius fan status LEDs:
Table. Fan status LEDs
LEDs Meaning
Red

Fan has failed, fan speed is out of acceptable range, or fan speed is not being reported. (This LED will be on if the corresponding fan has been removed.)

Replace the fan as soon as possible.

Off

Normal operation.

The following table describes the O/S disk activity and status LEDs:
Table. O/S disk activity and status LEDs
LEDs Meaning
Blue

If this LED is on and blue, the disk is operating normally and no problems have been detected. If the LED is flashing blue, this indicates disk activity. If the LED is on but not flashing, there is currently no disk activity.

Red

If this LED is on immediately after installing a new O/S disk, this indicates that the RAID configuration for the server is being rebuilt. The LED turns off after the RAID configuration is restored. The amount of time it takes for the RAID configuration to be rebuilt after a new disk drive is installed depends on the amount of user and system configuration data stored.

If this LED is on during the course of normal operation (not after installing a new O/S disk), either the disk has failed or the server’s RAID configuration has been degraded.
