Ports 0-7 can be configured as eight separate ports or combined into one or more groups called wide ports (one x4,
two x4s, one x8, and so on.). Similarly, ports 8-15 can be configured as eight separate ports or combined into one or
more wide ports. A single wide port cannot combine individual ports or PHYs sourced by different SAS cores.
When configuring a boot-device in a multi-path environment, the target must be connected to one or more ports on
the same SAS core with AutoPortConfig enabled. The boot device appears to the host system as a single device on the
active path. A different controller is managed by the multi-path environment as the passive path.
When configuring data-storage devices in a multi-path environment, the rule for creating wide ports applies, but
multiple ports from different SAS cores can be connected to the data-storage devices. The multi-path environment
manages data-storage devices that are presented by the controller more than once.

Replacing the Bracket

To replace the bracket for the Avago 12Gb/s SAS HBA, follow these steps:
1. At an ESD-safe workstation, remove the board from its ESD protective bag.
2. Use an ESD-safe #1 Phillips screwdriver to carefully remove the two Phillips screws that connect the bracket to the
board. The following figure shows how to unscrew the two screws located at the top edge and bottom edge of the
board.

ATTENTION Never apply pressure to the bracket or the heat sink when inserting
the board. Do not handle the board by the bracket. Do not handle the
heat sink at any time. Do not bend or twist the board at any time.
CAUTION Damaging the screw can void the warranty. To prevent damage to the
screw, make sure that the screwdriver is centered in the top of the
screw.
