have more than one fault condition. Those items in the state column with an asterisk (*) indicate a fault condition.

Disk drive fault LED

The disk drive uses an amber fault LED to identify various states. Those items in the state column with an asterisk (*)
indicate a fault condition.

SAS expander module fault LED

The SAS expander module component side has a green activity LED, labeled LED 3 on the PCBA, and an amber fault
condition LED, labeled LED 2 on the PCBA. Both LEDs can be difficult to view from the top, since the component side
faces the chassis sidewall. Those items in the state column with an asterisk (*) indicate a fault condition.
