Making External Connections to Cisco 4000 Series Routers 4-109

Powering Up the Router

Caution Never operate the router unless the chassis is completely closed to ensure

adequate cooling.

Take the following steps to power up the router:

Step 1 If you have an AC-powered system, plug the system power cord into a 3-terminal,

single-phase power source that provides power within the acceptable range

(100–240 VAC, 50–60 Hz, 3.0–1.5A).

Step 2 If you have a DC-powered system, refer to the preceding section “Connecting

Routers with a DC-Input Power Supply” to connect the input power supply.

Warning This product relies on the building’s installation for short-circuit (overcurrent)

protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S.

(240 VAC, 10A international) is used on the phase conductors (all current-carrying

conductors). (To see translated versions of this warning, refer to the appendix “Translated

Safety Warnings.”)

Step 3 Turn ON the system power switch. The LED labeled POWER on the front panel

should go on.

Step 4 Verify that the OK LED on the right side of the front panel goes ON after a few

seconds delay.

For more information on conﬁguring the router software, refer to the chapter “Software

Configuration.”
