Chapter 5 Troubleshooting the Installation
Troubleshooting the Processor Subsystem
Troubleshooting the Network Processor Card
The procedures in this section assume that the router is in the original factory configuration, and that you
have not made changes to your configuration file.
If the system ready LED does not go on as expected (see the “Identifying Startup Problems” section on
page 5-3), check the following items to help isolate the problem:
• Do all of the LEDs remain off when the system power switch is turned on?
–
If the LEDs stay off, first see the “Troubleshooting the Power Subsystem” section on page 5-4
and the “Troubleshooting the Cooling Subsystem” section on page 5-6 to ensure that both the
fans and the power supply are functioning properly.
–
If the power supply and fans appear operational but the system ready or enable LEDs are off,
suspect that an improperly connected port adapter has hung the system. Tighten all captive
installation screws, and then restart the system.
• Is the system ready LED on?
–
If yes, the system software has initialized successfully, and the system is operational.
–
If the system ready LED remains off, the system detected a processor hardware failure. (This
LED should be on in normal operation.) Contact a service representative for instructions.
Troubleshooting the Port Adapter and Fixed WAN Ports
Check the following to help isolate a problem with a port adapter or fixed WAN port:
• Are all enabled LEDs on?
If yes, the system is operational.
• Are any enabled LEDs off?
–
If the enabled LED on a port adapter is off, suspect that the adapter has pulled away from the
router. Reseat the adapter in its slot (you do not have to turn off the system power when
removing or replacing port adapters). After the system reinitializes the interfaces, the enabled
LED on the adapter should go on.
–
If the enabled LED on a fixed WAN port is off or if the port adapter’s enabled LED remains off,
the system detected a processor hardware failure. (This LED should be on in normal operation.)
Contact a service representative for instructions.
