Reconnecting Input Power and Powering Up the Router

The following procedures explain how to reconnect AC-input power to Cisco 7200 series routers,

power up the router, and verify a successful system boot.

Warning Read the installation instructions before you connect the system to its power source.

To reconnect AC-input power to Cisco 7200 series routers, complete the following steps:

Step 1 At the rear of the router, check that the power switch on the power supply is in the OFF

(O) position.

Step 2 Slide the cable-retention clip up, away from the AC receptacle, and plug in the power

cable.

Step 3 Secure the cable in the power supply AC receptacle by sliding the cable-retention clip

down until it snaps around the connector. The cable-retention clip provides strain relief

for the AC power cable (refer to Figure 5).

service. We recommend powering Cisco 7200 series routers from a 120 VAC, 15A

receptacle U.S. (240 VAC, 10A international) at the power source.

To power up Cisco 7200 series routers that have an installed AC-input power supply, complete the

following steps:

• Each port adapter is inserted in its slot, and its respective port adapter lever is in the

locked position.
