Information LED

This LED will be solid blue when the UID function has been activated. When this
LED fl ashes red, it indicates a fan failure. When red continuously it indicates an
overheat condition, which may be caused by cables obstructing the airfl 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 fl 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.

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