1.7.1cPCI 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.
