Replacing the Power Distribution Board
The power distribution board (PDB) routes power from the power supply to the rest of
the server system through an integral wiring harness. The PDB is covered by a metal
cage for safety, ventilation, and heat dissipation reasons. It is this whole assembly that
must be removed and replaced, not just the board.
Caution:
Before replacing any of the boards in the NSC2U Server, you must first take the server
out of service, turn off all peripheral devices connected to the system, turn off the
system by pressing the power button, and unplug the power cord(s) from the system
or wall outlet.
When handling this board, observe the normal safety and ESD precautions. (See
Appendix A, “Safety Information”
for more information.)
To safely remove the PDB, you must first remove the chassis top cover, the front panel
bezel, and the drive bay assembly, which sits in front of the PDB module in the chassis.
