Connecting the Cisco uBR10012 Chassis to a DC Power Source

Use the following procedure to connect the chassis to a DC power source:

Step 1 Double-check that the DC PEMs have been reinstalled in the system, and that no power has yet been connected to the Cisco uBR10012 chassis.

Step 2 Verify that the DC power source is turned off and is not supplying power to the Cisco uBR10012 chassis.

Caution If using the 2400W AC-input power shelf as the DC power source, verify that the AC-input power cords are not plugged into AC power outlets.

Step 3 Strip not more than 5/16 in. (8 mm) of insulation off the ends of the DC power leads (Figure 3-21).

Warning Use copper conductors only. Statement 1025

Step 4 Route the two sets of DC power leads through the square hole at the right front of the chassis. Position each set under one of the two DC power terminal blocks (Figure 3-22).

Step 5 Connect the DC power lead from the first external power source to the –48V terminal in the DC terminal block (this is the bottom terminal, as shown in Figure 3-23).
