4. Lock in all the hard drives so they engage with the new backplane.l
5. Re-attach the front panel bezel. For instructions, see “Re-Installing the Front Bezel” in Section 3.2.
6. If this is the last task you are performing inside the server chassis, replace the front top chassis cover,
reconnect the power cord(s), and reconnect any external devices.
5.9 Replacing the Power Distribution Board
The power distribution board (PDB) routes power from the power supply module(s) to the rest of the
server through an integral wiring harness.
To replace the PDB, you must first remove the following components:
•
Top cover
•
Support cross bar and all components attached to it
•
SAS HDD backplane board
•
All cables connections from the PDB at the other end (The cables are soldered onto the PDB
and the new board has a new set of cables attached.)
-- HDD backplane board power cable (from the backplane board, soldered on the PDB)
-- Baseboard SSI main power cable (from the 24-pin connector on the baseboard; bundle
soldered on the PDB)
-- CPU and DIMM power cables (one for each CPU, from the 8-pin connectors on the
baseboard; soldered on the PDB)
-- Fan control board power cable (from the 12-pin connector on the fan control board,
soldered on the PDB)
-- Auxiliary I/O power dongle (from any auxiliary PCI adapters installed and out of the PCI air
baffle, soldered on the PDB)
-- Baseboard power control signal cable (from the baseboard, soldered on the PDB)
Refer to Figure 24. Cable Routing” and Figure 7. Baseboard Components and Connectors” for the
location of the connectors where the cables are unplugged.
CAUTION: Before replacing any of the boards on the CG2200 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.
5.9.1 Removing the Old Power Distribution Board

3. Slide the power supply module(s) out a few inches to disengage it from the PDB.
4. Remove the support cross bar and all components attached to it. For instructions, see “Removing the
