Appendix D: TX Matrix Plus Power Requirements, Guidelines, and Specifications
Most sites distribute DC power through a main conduit that leads to frame-mounted DC
power distribution panels, one of which might be located at the top of the rack that
houses the TX Matrix Plus router. A pair of cables (one input and one return) connects
each set of terminal studs to the power distribution panel.
Figure 144 on page 439 shows a typical DC source cabling arrangement.

NOTE: All inputs on the DC power supply in slot PEM0 must be powered by
dedicated power feeds derived from feed A, and all inputs on the DC power
supply in slot PEM1 must be powered by dedicated power feeds derived from
feed B. This configuration provides the commonly deployed A/B feed
redundancy for the system.
