JCS 1200 Platform Power Overview

The JCS 1200 platform does not have a power switch. The platform has four power
connectors; each powers a power module. As viewed from the rear of the JCS 1200
platform, power connector 1 (top-right connector) supplies power to power module
bay 1, power connector 2 (bottom-left connector) supplies power to power module
2, power connector 3 (top-left connector) supplies power to power module 3, and
power connector 4 (bottom-right connector) supplies power to power module 4 (see
Figure 25 on page 61).

JCS 1200 Platform
Power modules 1 and 2 are redundant and provide power to Routing Engine bays
1 through 6; power modules 3 and 4 are redundant and provide power to Routing
Engine bays 7 through 12. To ensure power redundancy, a typical power configuration
is to supply power to power connectors 1 and 4 from one power source location
while supplying power to power connectors 2 and 3 from another power source
location. The power domains are shown in Figure 26 on page 62.
