Controller board runtime LEDs

Immediately after the server is powered up, the controller runtime LEDs illuminate briefly in a predetermined pattern as part of the POST sequence. At all other times during server operation, the illumination pattern of the runtime LEDs indicates the status of the controller, as described in the following table.

LED ID	Color	LED name and interpretation

1	Green	CR502: Expander Heartbeat LED. This LED flashes every 2 seconds during
		normal operation. Abnormal conditions are indicated as follows:
		• If the LED glows steadily, the expander has an internal problem.
		• If the LED flashes twice per second, the NVRAM is corrupt.
		In either case, the expander does not function.

2	Amber	CR510: System Error LED.

3	Amber	CR509: Diagnostics Error LED.

4	Amber	CR500: Drive Failure LED. A physical drive connected to the controller has failed.
		Check the Fault LED on each drive to determine which drive has failed.
5	Green	CR508: Activity LED for SAS port 4I.

6	Green	CR507: Activity LED for SAS port 3I.
