Connecting Dc Power - Cisco CGR 2010 Installing And Connecting

Installing and Connecting the Router
Power-Supply Modules
— Verify that the voltage at the router is within the rated operating voltage range of the product by using a meter
or issuing the show environment command. For normal operating voltages, see
11. If you have two power supplies, install the second power supply in the available slot and repeat Step 1 through Step
10.

Connecting DC Power

This section explains how to connect DC power to the Cisco CGR 2010 router.
Warning: Read the installation instructions before connecting the system to the power source. Statement 1004
To connect an DC power supply:
1. Verify that power is off to the circuit on the power supply that you are removing. As an added precaution, place the
appropriate safety flag and lockout devices at the source power circuit breaker, or place a piece of adhesive tape
over the circuit breaker handle to prevent accidental power restoration while you are working on the circuit.
2. Observe the power-input terminal on the left edge of the router cable side. See
Figure 9 Power-Input Terminal Designations

Note that the line connection for AC power and the negative connection for high-voltage DC power
share the same power input terminal—that is, this terminal can be used for either AC or DC power. The
same is true for the terminal for the neutral connection for AC power and the positive connection for
high-voltage DC power—the same terminal can be used for either AC or DC power.
Note: The power-supply module 1 connection is labeled PSU1, and the power-supply module 2 connection is
labeled PSU2. Ensure that you connect the wires to the correct terminal screws.
3. Use twisted-pair copper wire to connect from the power-input terminal to the power source.
Note: Use 12-AWG (minimum) for the low-voltage DC power supply module. Use 14-AWG (minimum) or 12-AWG
(maximum) for the high-voltage DC or AC power supply module.
4. Strip each of the two wires to 0.25 inch (6.3 mm) ± 0.02 inch (0.5 mm). See
