•Is the FE ENABLED LED on?

—If yes, the Fast Ethernet port on the I/O controller is initialized and enabled for ope ration.

—If the FE enabled LED remains off at system startup, there is probably a problem with the

Fast Ethernet port on the I/O controller.

These procedures assume that the I/O controller card, network processor card, and router shelf are

in the original factory configuration and that you have not mad e changes to your configuration file.

•Is the I/O controller card enabled LED on? (This LED should light in normal operation.)

—If the I/O controller card enabled LED does not light as expected and you have checked the

I/O controller card, make sure that the power to the router is OFF, reseat the network

processor card in its slot, and restart the router.

—If the enabled LED remains off, the system detected a processor hardware failure. Ensure

that a partially seated port adapter i s not caus ing the s ystem to ha ng. Procee d to th e follo wing

section, “Troubleshooting the Port Adapters.”

Check the following to help isolate a problem with the port adapters:

•Are all port adapter enabled L EDs on?

If yes, the system is operational.

•Are any port adapter enabled LEDs off?

—If the enabled LED on an individual port adapter is off, suspect that the port adapter has

pulled away from the midplane. Reseat the port adapter in its slot and verify that the port

adapter levers are in the locked position. (You do not have to power OFF system power whe n

removing or replacing port adapters.) After the system reinitializes the interfaces, the

enabled LED on the port adapter should light.

—If the enabled LED remains off, suspect a faulty port adapter. Replace the port adapter with

a new one.

If the new port adapter enable LED fails to light, there may be a problem with the I/O

controller card or the network processor card. Contact a service representative for

instructions.

Check the following to help isolate a problem with the interconnect port adapter:

•Is the dial shelf interconnect port adapter enabled LED on?

—If yes, the system is operational.

—If no, verify that the interconnect port adapter is seated properly and that the port adapter

levers are in the locked position.

If the enabled LED remains off, reseat the port adapt er and veri fy tha t the port a dapter le v ers

are in the locked position. Use the reload command to reload the system software.

—If the enabled LED remains off, see t he sect ion “T rou ble shoot ing the Power Subsystems” to

check your power connections.
