You connect DC power to the router by using a terminal jumper to attach one DC power
cable from the DC power source to two terminal studs on the power supply faceplate.
Use the terminal jumper kit (model number PWR-T-BUS-BAR-S) to perform this
procedure. The terminal jumper kit contains the terminal jumpers and the new clear
plastic cover required to accommodate the terminal jumpers. Six terminal jumpers are
required for each power supply. You must provide power cables (the cable lugs are
supplied with the router).
CAUTION: When using a terminal jumper for this procedure, terminate only
a single DC power cable to the two input terminals using the terminal jumper
as shown in Figure 83 on page 137
