Removing the power distribution board:
If installed, remove the front bezel.
Turn off the server modules using the operating system commands or the CMC.
Turn off the enclosure, including any attached peripherals, and disconnect the enclosure from the electrical outlet and peripherals.
To reduce the chassis weight, remove the following (if required):
hard drives
server modules
Remove the power supply units (PSUs).
If applicable, rotate the system feet inward and lay the system on its side on a flat stable surface, with the cover release latch side on top.
Open the system.
Loosen the spring-loaded screw securing the power distribution board (PDB) bracket to the PSU cage.
Holding the handle, lift the PDB bracket upward and away from the chassis.
Remove the three screws securing the PDB to the PDB bracket and remove the PDB from the bracket.
Removing and installing the power distribution board
a. PDB bracket
b. handle
c. spring-loaded screw
d. PDB connector on power pass-through board
e. screw hole for PDB bracket on the PSU cage
f. PDB connector on the system board
Power distribution board connectors
1. PSU connectors (4)
2. connector to system board
3. power pass-through board connector
Installing the power distribution board:
Align the screw holes on the PDB with the screw holes on the PDB bracket.
Install the three screws to secure the PDB to the bracket.
Holding it by the handle, position the PDB bracket so that the two PDB edge connectors align with the connectors on the system board and the power pass-through board.
Aligning the slot on the PDB bracket with the metal standoffs on the chassis wall, slide the PDB into the connectors until firmly seated.
When firmly seated, the spring-loaded screw on the PDB bracket aligns with the screw hole on the power supply unit (PSU) cage.
Tighten the spring-loaded screw to secure the PDB bracket to the PSU cage.
Close the system.
If applicable, place the system upright on a flat, stable surface and rotate the system feet outward.
Reinstall the PSUs.
If removed, reinstall the hard drives and server modules.
Reconnect the enclosure to its electrical outlet and turn the enclosure on, including any attached peripherals.
Turn on the server modules using the operating system commands or the CMC.
If applicable, install the front bezel.
