Replacing the SAS/SATA Backplane Board

The six-slot SAS/SATA 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. In order to access the SAS/SATA
backplane board to remove it, you need to first remove the following components:

• Front bezel
• SAS/SATA control module or hardware RAID module, if installed, or empty bracket
• Any hard disk drives installed
• HDD bay assembly cover plate
• The power cable connected to the front of the backplane board

CAUTION: Before replacing any of the boards on the CG2100 server, you must 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/SATA backplane board, observe the normal safety and ESD
precautions. See “Appendix A: Safety Information” for more information.
