CR502: Expander Heartbeat

This LED flashes every two seconds during normal
operation. If the LED glows steadily, the expander

cannot function due to an internal problem. If the
LED flashes twice per second, the expander

cannot function because the NVRAM is corrupt.

Amber

CR510: System Error

The controller ASIC has locked up and cannot
process any commands.

Amber

CR509: Diagnostics Error

One of the server diagnostics utilities has detected
a controller error.

Amber

CR500: Drive Failure

To determine which drive has failed, check the

Fault LED of each physical drive connected to the
controller.

Green

CR508: Activity

Port 4I is active.
