Index LED Function Color LED Off LED On LED Flash
A Power Green No power Full power Standby power1 (FSP function running)
B Identify Blue Normal Identify N/A
C System information Amber Normal Requires attention N/A
D Enclosure fault roll-up light Amber Normal Fault N/A
F Function/Data display        
Notes:
  1. During CEC power-on, there is approximately a 30-second transition period between flashing to solid when the LED might flash faster.

In Figure 3:
  • The amber P1/P2! fault roll-up LED is lit solid when a faulty or failed part in the upper domain of the system has been detected.
  • The amber P1/P2! fault roll-up LED is flashing when a part in the upper domain was selected by using the identify function.

In Figure 4:
  • The amber P3/P4! fault roll-up LED is lit solid when a faulty or failed part in the lower domain of the system has been detected.
  • The amber P3/P4! fault roll-up LED is flashing when a part in the lower domain was selected by using the identify function.

AC power LED (Green) DC power LED (Green) Error and identify LED (Amber) Power supply status
On (Solid) On (Solid) Off The power supply is operating correctly. See  B  in Figure 9.
On (Solid) Flashing Off The system is turned off, but the power supply is still connected to the power source. See  B  in Figure 9.
On (Solid) Off On The power supply is not operating correctly. See  C  in Figure 9.
On (Solid) On (Solid) Flashing The faulty or failed power supply was selected by using the identify function. See  D  in Figure 9.
