4-3 Control Panel LEDs
The four control panels are located on the front handle of the SCF418 chassis. Each control panel has two additional LEDs. These LEDs 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.
•Informational LED:
Continuously on and blue: UID function has been activated.
Flashing red: Fan failure.
Continuously on and red: Overheat condition. This 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 or fan failure condition exists.
