Replacing Connections to the Router

To make final connections to the router, perform the following steps.

Warning

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

translations of the warnings that appear in this publication, refer to the

Regulatory Compliance and

Safety Information

document that accompanied this device.

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 turn green. The power

LED on the left side of the rear panel, and the LED near the power supply switch should also turn green.

Step 4 Check the system LED on the left side of the front panel, and the system LED on the left side of the rear

panel to verify that they are green, after a few seconds delay when booting.

Step 5 If you have problems, see the “Obtaining Technical Assistance” section on page 29.

Powering On the Router

Caution To ensure adequate cooling, never operate the router unless the unit is completely closed.

To power on the router, perform the following steps:

Step 1 For routers with AC input, plug the router’s power cord into a three-terminal, single-phase power source

that provides power within the acceptable range.

Step 2 Power on the router. The LED labeled SYSTEM on the front panel should come on.
