Chapter 3 Installing and Connecting the Router
Power-Supply Modules
Figure 3-11 Using Tie Wraps with the Strain Relief Mechanism
Caution Ensure that all strands of a stranded wire are properly captured into the terminal block. A loose strand
could possibly short the chassis and result in a hazard.
e. Use minimum 14-AWG or maximum 12-AWG copper wire to connect the router to a 15-A branch
circuit in accordance with local electrical code requirements.
Step 6 Fully insert the un-insulated lead in to the terminal block and screw each captive screw on the terminal
block tight to ensure proper connection.
Caution The AWG size of the wires feeding power to the input terminal block is a minimum of 14 AWG (2.0
mm
2
) or a maximum of 12 AWG (3.309 mm
2
), all for a 15 Amp branch circuit. 12 AWG is the largest
wire that the terminal block will accept.
Step 7 Torque the captive screws (above the wires) to 8.5 in-lb (± 0.5 in-lb).
Caution Stay clear of the terminal block when energy has been restored. The terminal block screw heads and any
exposed wiring could have hazardous line voltages (depending on the voltage source). The Cisco CGR
2010 router is intended to be installed in a restricted access location and serviced by trained personnel
only.
Step 8 Connect the other end of the positive wire (the wire connected to +) to the positive terminal on the DC
power source.
Step 9 Connect the other end of the negative wire (the wire connected to -) to the negative terminal on the DC
power source.
Step 10 Turn on the power at the DC circuit, then verify that the following LEDs are green:
• On the power-supply module: PSU OK LED. See Figure 1-6 on page 1-8.
• On the router: PSU1 (bottom) or PSU2 LED (top). See Figure 1-6 on page 1-8).
• 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
