(G) Removing the Cable Bundle Bracket and Fan Cage

Both the cable bundle bracket and the fan cage have to be removed in order to perform tasks such as replacing any of the boards
in the front of the server: the front panel board, the LED/switch board, the telco alarms module, or the fan controller board as
well as working on components or connectors on the server board front edge, or replacing the server board.
The cable bundle bracket is under the support cross bar and just behind the fan cage. It is attached to the fan cage by two small
screws. Because both of these components need to be removed and are fastened together, they are treated as one assembly.
Before you can remove the cable bundle bracket/fan cage, you must first remove (and unplug were applicable)
» the chassis cover
» All six fans from the cage. Set the fans aside.
» The support cross bar and all the components attached to it
» The four power cable bundles. Move them away from the FCB.
» All three fan cables from the fan control board.
For instructions, see (A), (D), (E1), and (E5) in Chapter 4.
To remove the fan cage:
1. Unfasten the two screws that fasten the fan cage to the chassis floor. Pull the cage up out of the chassis and set it and the
screws aside.

(H) Removing the SAS Hot-Swap Backplane (HSBP) Board

The HSBP board has to be removed in order to perform tasks such as replacing the HSBP board or replacing the PDB.
CAUTION: Before removing or replacing any of the boards on the CG2300 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 backplane board, observe the normal safety and ESD precautions. See "Appendix A: Safety Information"
for more information.
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.
Before you can remove the HSBP board, you must first remove the chassis cover and front bezel. For instructions, see (A) and (I) in
Chapter 4.
Once you have removed the HSBP board from the drive bay assembly, you need to remove the four cables connected to the
board:
» SAS HDD backplane board power cable.
» SAS 1 and SAS 2 cables
» HSBP I C/HDD LED cable

For instructions, see (E3) and (E4) in Chapter 4.
To remove the HSBP board:
1. Slide any hard disk drives out from the drive bay slots to disengage them from the backplane.
2. Remove the cover plate on the HDD bay assembly by loosening the screw that fastens it to the drive bay and sliding it to
the left towards the chassis wall to release the tabs. (Figure 15, "A" and "B")
