Replacing Connections to the Router
To make final connections to the router, follow these steps:
Step 1 Replace all network connections.
Step 2 Do one of the following:
• AC-powered router: Plug the power cord into a 3-terminal, single-phase power source that
provides power within the acceptable range (100 to 240 VAC, 50 to 60 Hz).
• DC-powered router: Remove the tape from the circuit breaker switch handle and reinstate power
by moving the handle of the circuit breaker to the ON position.
Step 3 Turn ON the power switch. The power LED on the front panel of the router should come on.
Step 4 Check the Sys LED on the right side of the front panel to verify that it goes on after a few seconds delay
when booting.
Step 5 If you have problems, see the “Obtaining Technical Assistance” section on page 28.
Step 6 Proceed to the “Recovering Compact Flash Memory and System Images” section on page 27.
