Troubleshooting the Power Subsystem
If this LED remains off when you start the router, it is probably a problem with the network
processor card. Contact your service representative for technical assistance.
Each enabled LED goes on and indicates that the port is initialized and enabled for operation
by the system. These LEDs go on during a successful router boot and remain on during normal
operation of the router. If an enabled LED fails to go on, proceed to the Troubleshooting the
Port Adapter and Fixed WAN Ports section on page 5-5.
If any of the LEDs remain off when you start the router, it is probably a problem with the port.
Proceed to the Troubleshooting the Port Adapter and Fixed WAN Ports section on page 5-5.
The slot 0 and slot 1 LEDs only go on when the PC Card slot is being accessed by the system.
These LEDs remain off during normal operation of the router and do not indicate startup
problems.
The initial system banner should be displayed on the console screen.
If it is not displayed, see the Connecting the Console Port and Auxiliary Port section on page 3-16
to verify that the terminal is set up correctly and that it is properly connected to the routers console
port.
Troubleshooting the Power Subsystem
Check the following to help isolate a problem with the power subsystem:
Is the power LED on?
If yes, the power source is good, and the power supply is functional.
If no, make sure the power cable is connected at both ends.
If the power LED remains off, and the power switch is set correctly, suspect the power source
or the power cable. Turn the switch off, connect the power cable to another power source, if
available, and turn the switch back on. If the LED goes on, the problem is the first power source.
If the power LED fails to go on after you connect the power supply to a new power source,
replace the power cord, and turn the switch back on. If the LED goes on, return the first power
cable for replacement.
If the LED still fails to go on when the power supply is connected to a different power source
with a new power cable, the power supply is probably faulty. Contact a service representative
for further instructions.
Troubleshooting the Processor Subsystem
The processor subsystem comprises the network processing card and the ports. The system can operate
without a port adapter installed as long as none are in partial contact with the connector pins. A port
adapter that is partially connected to the router sends incomplete signals to the processor, which faults
the Peripheral Component Interconnect (PCI) bus and causes the system to hang. Therefore, first ensure
that the system software has initialized successfully. Then, if necessary, you can troubleshoot a port
adapter.
