3.1 Overview
The power subsystem consists of the offline switchers (OLSs), the midplane and backplane
power buses, the DC-to-DC converters (power bricks) on the Everest CPU, VCAM, and
memory boards, and the various power boards. The following power boards can be
installed: 505 (Cardcage 3 only), 512, dual 505 (also known as the 505x2), 512S (in the
SCSIbox 2), and System Controller. See Figure 3-1 for a block diagram illustrating the
power subsystem components.
