Step 1 Check that the power switch (2) is in the off (O) position.

Step 2 Plug the power cable into the AC connector (1) on the router.

Step 3 Plug the AC power supply cable into the AC power source.

Connect DC-Input Power

Note

The color coding of the DC-input power supply leads depends on the color coding of the DC power source at your site.

 

 

Make certain the lead color coding you choose for the DC-input power supply matches lead color coding used at the

 

 

DC power source.

 

 

 

 

 

 

 

 

Warning

 

Before completing any of the following steps, and to prevent short-circuit or shock hazards, ensure that power is

 

 

 

removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that

 

 

 

services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit

 

 

 

breaker in the OFF position.

 

 

 

 

 

Step 1

At the rear of the router, check that the power switch is in the off (O) position.
