1.7.1 cPCI Power Supply Modules
The Compact PCI (cPCI) Power Supply Modules provide +/-12V, 5V, and 3.3V DC power to
the cPCI backplane for use by the cPCI electronic modules. Each RAN requires one power
supply module. Two modules can be used to provide redundancy if desired. These modules are
hot swappable. Figure 8 shows the cPCI Power Supply Module faceplate. Table 4 describes the
faceplate components called out in the figure.
