DC Power Lugs

The accessory box shipped with the router includes the cable lugs that attach to the
terminal studs of each power supply. (The cable lug shown in Figure 189 on page 355 is
also used for the grounding the chassis.)

CAUTION: Before router installation begins, a licensed electrician must attach
a cable lug to the power cables that you supply. A cable with an incorrectly
attached lug can damage the router.

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 router. A pair of cables (one input and one return) connects each set of
terminal studs to the power distribution panel.
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 PEM 1 must be powered by dedicated power feeds derived from
feed B. This configuration provides the commonly deployed A/B feed
redundancy for the system.
Figure 190 on page 356 shows a typical DC source cabling arrangement.
