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.
