Riser card assembly and plastic guide
•
SAS/SATA control module or hardware RAID module if either is installed

All cables connected to the PDB or components that have to be removed to access it:
-- HDD power cable
-- SAS/SATA control module or SAS/SATA hardware RAID module flex circuit cable
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 power distribution board, observe the normal safety and ESD
precautions. See Appendix A: Safety Information for more information.
Removing the Old Power Distribution Board
1.
Power down the server and unplug all peripheral devices and the power cable(s).
2.
3.
Remove the riser card assembly. For instructions, see “Removing the Riser Card
Assembly” in Section 3.2.
4.
Remove the black plastic riser card assembly/bridge board guide bracket by
loosening the two screws that secure it to the chassis base. See Figure 57 for the
location of this bracket and the screws that attach it.
5.
Slide the power supply module(s) out a few inches to disengage it from the PDB.
6.
Remove the SAS/SATA control module or SAS/SATA hardware RAID module, if installed.
See Section 4.3, “Installing a SAS/SATA Control Module” or Section 4.4, “Installing
a Hardware RAID Module” for help with how these modules are fastened.
NOTE: Other components that are removed to fully install a SAS/SATA module do not
need to be touched when replacing the PDB; only the sheet metal cover, the module
itself, and the flex cable connection on the SAS/SATA module side.
7.
Remove the black plastic cover that shields the PDB.
There are two screws that fasten this cover below where the SAS/SATA modules are
installed. (Figure 64, “A”)
8.
Loosen the two screws that secure the PDB to the chassis and save them for re-
installing the new board. (“C”)
9.
Gently pull the five edge connectors away from the T5520UR server board to free the
PDB from the chassis. (“D”)
10.
Unplug the power distribution cable from the PDB. (“B”)
