Powering On the Router and Observing the Boot Process

The first time you start the router, observe the following conditions:

Step 1 Switch on all the circuit breakers that control power to the router.

Step 2 Observe the power entry module LEDs:

•AC PEMs—The green PWR OK LED should be on and the power supply fan operating.

•DC PEMs—The green PWR OK LED should be on and the power supply fan operating.

Step 3 Check the blower module:

•Ensure that the green OK LED is on.

•Listen for the blowers in the blower modules; you should hear them operating immediately. In a noisy environment, the blowers may be difficult to hear. You can place your hand in front of the exhaust vents near the top rear of the chassis to verify that the blower is operating.
