Implements an enclosure management module that is responsible
for providing enclosure management functions for storage
enclosures and server backplanes.
J1A3 Local Battery Backup Unit connector 20-pin connector
Connects the LSIiBBU09 unit directly to the RAID controller.
J1A4 SCS Backplane Management connector 3-pin shielded header
Implements an enclosure management module that is responsible
for providing enclosure management functions for storage
enclosures and server backplanes.
J1B1 Individual PHY and Drive Fault Indication
header
Ports 3 to 0
Ports 7 to 4
2x8-pin header
Connects to an LED 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.
