explains what each LED indicates when illuminated and any corrective action you may need to
take.
HDD: Indicates IDE channel activity. SAS/SATA drive activity when flashing.
NIC1: Indicates network activity on GLAN1 / 2 when flashing.
Overheat/Fan Fail: This LED indicates a fan failure when flashing.
When Continuously On (not flashing): This LED indicates an overheat condition 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 the 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.
