Replacing the SAS Backplane

The six-slot SAS backplane board is located at the rear of the HDD drive bay assembly. It is held in place by a cover plate on top
of the HDD bay assembly that goes over the top edge of the backplane board. There is also a black plastic air duct surrounding
the drive bay on the right side and rear of the assembly.
CAUTION: Before replacing any of the boards on the CG2300 server, first take the server out of service, turn off all peripheral
devices connected to the server, turn off the server by pressing the power button, and unplug the power cord(s) from the system
and wall outlet.
When handling the SAS backplane board, observe the normal safety and ESD precautions. See "Appendix A: Safety Information"
for more information.
Removing the Old SAS Backplane Board
In order to replace the SAS backplane board, you need to first remove the following components: the chassis cover and the front
bezel. For instructions, see (A) and (I) in Chapter 4.
Once the SAS backplane board in accessible, you also need to disconnect the power cable and the two SAS connectors. For
instructions, see (E4) in Chapter 4.
The complete procedure for removing the SAS backplane board is covered in (H) in Chapter 4.
NOTE:
1. Once the backplane board is removed and the cables disconnected, remove the HDD air duct from the old backplane
board by loosening the two screws on the backplane. (Figure 49, "A")
