Step 3
If necessary, use a wire stripper to strip approximately 0.55 in. (14 mm) from the –48V,
+48V, and ground leads. (See Figure 41.)
Figure 41 Stripping the DC-Input Leads
Note The ground lead for the Cisco uBR7200 series DC-input power supply consists of
a two-hole grounding lug that connects to an M5 grounding receptacle; you do not need
to strip this ground lead.
Step 4 For Cisco 7200 series routers, insert the stripped end of the ground lead all the way into
the ground lead receptacle on the DC-input power supply, and tighten the receptacle
screw using a 3/16-inch flat-blade screwdriver. (See Figure 39.)
For Cisco uBR7200 series routers, connect the two-hole grounding lug on the grounding
lead to the M5 grounding receptacles with the M5 nuts. Tighten the nuts using an 8-mm
wrench or nut driver (or adjustable wrench). (See Figure 40.)
Step 5 Insert the stripped end of the +48V lead all the way into the +48V lead receptacle and
tighten the receptacle screw using the same 3/16-inch flat-blade screwdriver. Repeat this
step for the –48V lead.
