Because the power module LEDs and the monitoring circuits are redundantly powered by the other

Note

power module in the power shelf load zone PEM pair, the LED labeled FAULT on the PEM can be on

even when the circuit breaker for that PEM is switched off or there is no DC-input power source for that

PEM. On a newly installed PEM, when DC-input source power is available to the PEM and the circuit

breaker is switched on, the LED labeled FAULT should go off and the LED labeled PWR OK should go

on.

Visually check the two LEDs on the front of each blower module. When the blower module is operating

Step 5

correctly, the green LED labeled OK should be on and the red LED labeled FAIL should be off. Listen

for the blowers in the blower modules; you should immediately hear them operating. In a noisy

environment, the blowers might be difficult to hear; therefore, place your hand in front of the exhaust

vents near the top and bottom rear of the chassis to verify that the blowers are operating.

Visually check the LEDs on the two alarm cards. When the system is operating correctly, the following

Step 6

LED conditions should be true:

Step 7

On the console terminal, verify that the console displays the system banner and that the system and all

interfaces initialize successfully.

If the power supplies do not power up, or if the system or any interfaces do not initialize properly, refer

to the Cisco 12016, Cisco 12416, and Cisco 12816 Router Installation and Configuration Guide that

shipped with your router for additional information and installation troubleshooting procedures. If you

are still unable to resolve the problem, contact your Cisco service representative for assistance.

Reinstalling the Chassis and Scissor-Jack Platform in the Shipping Pallet

To install the chassis and scissor-jack platform on the shipping pallet, use

follow these steps:

Step 1

Use the bolts you removed earlier to attach the eight hold-down brackets to the four sides of the

scissor-jack platform (two brackets on each side).

When a DC-input PEM is seated in its power shelf bay, connected to a DC power source supplying

power within the required range, and the circuit breaker on the faceplate of the PEM is switched on,

the green LED labeled PWR OK on the PEM faceplate should be on and the PEM fan should also

be on. This is normal behavior.

All three system alarm LEDs should be off.

The alarm card status LED labeled ENABLED should be on; the LED labeled FAIL should be off.

The LED labeled ENABLED for each CSC and SFC in the switch fabric card cage should be on; the

LED labeled FAIL should be off.
