Information LED

This LED will be solid blue when the UID function has been activated. When this

LED ashes red, it indicates a fan failure. When red continuously it indicates an

overheat condition, which may be caused by cables obstructing the airow in the

system or the ambient room temperature being too warm.

Check the routing of the cables and make sure all fans are present and operating

normally. You should also check to make sure that the chassis covers are installed.

Finally, verify that the heatsinks are installed properly (see Chapter 5). This LED

will remain ashing or on as long as the indicated condition exists.

Power Fail

This LED functions only when two power supply modules have been installed in the

system and indicates a power supply module has failed (when illuminated). This

should be accompanied by an audible alarm. A backup power supply module will

take the load and keep the system running but the failed module will need to be

replaced. Refer to Chapter 6 for details on replacing the power supply. This LED

should be off when the system is operating normally.

3-4 Drive Carrier LEDs

•Green: Each hard drive carrier has a green LED. When illuminated, this green

LED (on the front of the hard drive carrier) indicates drive activity. A connec-

tion to the backplane enables this LED to blink on and off when that particular

drive is being accessed. Please refer to Chapter 6 for instructions on replacing

failed hard drives.

•Red: The red LED to indicate a hard drive failure. If one of the hard drives fail,

you should be notied by your system management software. Please refer to

Chapter 6 for instructions on replacing failed hard drives.
