Chapter 3: Fault Management

In this section the fault management process of the Series 

RAID controller is discussed. How to interpret the status 

LEDs on the front of the controller is also described.

An SES firmware process handles all enclosure fault 

management. The process polls the environment every ten 

seconds. The controller firmware communicates with the 

SES device via Send Diagnostics and Receive Diagnostic 

SCSI command.
