10.2 Power and Fan Subsystems
The power bay provides space for four power supply modules and the power distribution board(PDB). The dimensions
of the power supply are 3.72-inches (W) x 15.75-inches (D) x 1.57-inches (H). There are two dual-motor fans located
within each power supply drawing air through the hard drives and across the power distribution board. Also refer to
Section 10.2.2 for details. Each power supply module has a handle to assist insertion and extraction without tools. The
PDB distributes the power in two ways. There is a connector on the back edge of the board that mates to the power
supplies. In addition, there are cables that route power up to the main board and to the hot-swap backplane. The AC
power is filtered with a combination 15A power plug integrated with a filter.
