About Fan Tray LEDs
The Thermal Fault LED on the system status and control panel indicates the overall
status of the cooling system. The Thermal Fault LED lights when a fan fault or
overtemperature condition is detected. LEDs inside the system indicate the fault
status of each fan tray assembly.
The fan tray LEDs are located beside or beneath each fan tray assembly. There are
three LEDs per fan tray, as shown below.
