MegaRAID SAS RAID Controller Characteristics
6Gb/s MegaRAID SAS RAID Controller Family
J2D1 Standard Edge Card connector The RAID controller interfaces with the host system though a
standard edge card.
This interface provides power to the board and an I 2 C
interface connected to the I 2 C bus for IPMI.

J4A2 Activity LED header 2-pin connector
Connects to an LED that indicates activity on the drives
connected to the controller.

Connects to an LED that indicates whether a drive is in a
fault condition.

Ports 8 to 11
Ports 12 to 15
2x8-pin header
Connects to an LED array that indicates whether a drive is in
a fault condition. 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.
