Figure 106. LEDs on an 8335-GCA or 8335-GTA system

LED indicators are located on the following parts:

v At the front of the system:

– Disk drives (green LED indicates activity; amber LED indicates a problem)

– Fans (green LED indicates activity; amber LED indicates a problem)

v At the rear of the system:

– Backplane, near the rear LAN port: Green, amber, and blue (same as on the front next to the power

button)

– Power supplies (Two green LEDs indicate AC and DC power; amber LED indicates a problem)

Identifying the 8335-GCA or 8335-GTA that needs servicing

Use the Intelligent Platform Management Interface (IPMI program to turn on the blue identify LED to

help you find the system that needs servicing.

Procedure

Use the ipmitool command to activate the blue system identify LED.

For in-band networks, the chassis identify command is:

ipmitool -I <interface> chassis identify <interval>

Where:

interface

Is the interface you are using to connect to the system; for example usb.

interval

Is the time to turn on the identify LED in seconds. The default is 15; meaning the LED is on for

15 seconds then turns off. A value of zero (0) turns off the LED. A value of force turns on the

LED and leaves it on until turned off.

To run the command remotely over the LAN, the chassis identify command to enter is:

ipmitool -I lanplus -H <hostname> -U <username> -P <password> chassis identify <interval>
