5.2.9 Removing the Power Distribution Board
The power distribution board (PDB) provides the circuitry that distributes power to
the other components in the system. The PDB also contains an electronic copy of the
chassis serial number (see
Section 2.3, “Obtaining the Chassis Serial Number” on
page 2-10 ). When you replace this board, you must run certain service commands to
update the replacement PDB with the chassis serial number. The steps to perform
these service commands are provided in
Section 5.2.10, “Replacing the Power
Distribution Board” on page 5-30 .
Caution –
The system supplies power to the power distribution board even when
the system is powered off. To avoid personal injury or damage to the system, you
must disconnect power cords before servicing the PDB.
1. Perform the procedures described in Section 5.1, “Common Procedures for Parts
Replacement” on page 5-1 .
2. Disengage both power supplies from the power distribution board.
To disengage a power supply, push the power supply latch to the right and pull the
power supply out a few inches to disengage it from the PDB (
