Indicates drive faults. There is one LED per 
port. When lit, each LED indicates the 
corresponding drive has failed or is in the 
Unconfigured-Bad state. Refer to the 
MegaRAID SAS Software User’s Guide for 
more information about drive states.

The LEDs function in a direct-attach 
configuration (there are no SAS expanders). 
Direct attach is defined as a maximum of 
one drive connected directly to each port.

Note: This header is used for RAID 

controllers with internal SAS ports
