Installing and Connecting the Router
Power-Supply Modules
Figure 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.
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 mm2)
or a maximum of 12 AWG (3.309 mm2), all for a 15 Amp branch circuit. 12 AWG is the largest wire that the
terminal block will accept.
7. Torque the captive screws (above the wires) to 8.5 in-lb (± 0.5 in-lb).
Caution: Do not touch the terminal block after energy is 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.
8. Connect the other end of the positive wire (the wire connected to +) to the positive terminal on the DC power source.
9. Connect the other end of the negative wire (the wire connected to -) to the negative terminal on the DC power
source.
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 6 on page 12 .
— On the router: PSU1 (bottom) or PSU2 LED (top). See Figure 6 on page 12 ).
— 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 Table 1 on page 30 .
11. If you have two power supplies, install the second power supply in the available slot and repeat Step 1 through Step
10.
Protecting the Terminal Block from Exposure
You can protect the Cisco CGR 2010 router terminal block from exposure with the terminal block cover. See Figure 12
on page 37 .
