Install the Hardware
The Cisco 7505 router supports AC-input and DC-input power supplies. The power supply is already installed
in the router when you receive it. You connect the power to it.
Note The AC-input power supply is the shipped as the default if no power supply is specified at the time of
purchase.
Connect the AC-Input Power Supply
Step 1 Push the cable retention clip away from the power supply receptacle, and push the power cable in
until the cable retention clip snaps into place.
Step 2 Connect the opposite end of the power cable to an appropriate power source.
Connect the DC-Input Power Supply
Step 1 Turn off the power source. Locate the circuit breaker on the panel board that services the DC circuit,
and switch it off, then tape the switch handle of the circuit breaker in the off position.
