Power Distribution Board

The power distribution board is located in your system directly behind the

power supply fan modules. This feature provides additional cooling to the

power supplies through the power distribution shroud that routes airflow to

the power supplies. See Figure 2-19.

Remove the power supplies from the system. See "Removing a Power

Supply" on page 77.
