NIC1: Indicates network activity on GLAN1 when flashing.

Overheat/Fan Fail: When this LED flashes it indicates a fan failure. When
continuously on (not flashing) it indicates an overheat condition, which may be
caused by cables obstructing the airflow 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. This LED will remain flashing or on as long as the overheat
condition exists.
•
Red: The SAF-TE compliant backplane activates the red LED to indicate a drive
failure. If one of the SCSI drives fail, you should be notified by your system
management software.
