Plugs and Pin-Outs
The following is a brief overview of connecting to DC power. Details can be found in the Cisco IR829
Integrated Services Router Hardware Installation Guide and should be understood before beginning. See
The IR829 ships with a DC power accessory kit that contains a 4-pin locking connector and pins to use
for the power connections. Four contacts are supplied, but only three are used. One is a spare.
The power entry receptacle is on the IR829. The pin-outs are shown in

Step 1
Identify the DC power source and measure 4 strands of copper wire 16
AWG (1.29mm) long enough to connect to the DC power source.
Note
The maximum length of the cable
before
twisting is 15 feet (4.6
meters).
Step 2
Using an 16-gauge wire-stripping tool, strip each of the wires coming
from each DC-input power source to 0.25 inch (6.3 mm) ± 0.02 inch (0.5
mm). Do not strip more than 0.27 inch (6.8 mm) of insulation from the
wire. Stripping more than the recommended amount of wire can leave
exposed wire from the power connector after installation.
