3-3 Control Panel LEDs
The control panel located on the front of the SC732D4-903B chassis has three LEDs
that provide you with critical information related to different parts of the system.
This section explains what each LED indicates when illuminated and any corrective
action you may need to take.
Overheat/Fan Fail
When Flashing:
This LED indicates a fan failure.
When Continuously On (not flashing): This LED indicates an overheat condi-
tion caused by cables obstructing the airflow in the system or the ambient room
temperature being too warm.
Correcting an Overheat/Fan Fail Condition
1. Check the routing of the cables and move any cables that restrict airflow.
2. Confirm that all fans are operating normally.
3. Verify that the heatsinks are installed properly.
4. If the chassis cover is not aligned correctly, the airflow may be disrupted. This
leads to overheating. Confirm that the chassis cover is placed correctly.
5. This LED will remain active as long as the overheat condition exists.
HDD: Indicates IDE channel activity in the SAS/SATA drive, and/or DVD-ROM drive
activity when flashing.
NIC: Indicates network activity on GLAN when flashing.
