Table 2. Technical Specifications

Specification
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.
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 only.
For factory and debug use
