Troubleshooting

Your Cisco 3600 series router goes through extensive testing and burn-in before leaving the factory. If you encounter problems, use the information in this appendix to help isolate problems or to eliminate the router as the source of the problem.

This appendix contains the following sections:

Note To troubleshoot a network module, see the Cisco Network Modules Hardware Installation Guide; to troubleshoot a WAN interface card, see the Cisco WAN Interface Cards Hardware Installation Guide.

If you cannot locate the source of the problem, contact a customer service representative for information on how to proceed. For technical support information, see the Cisco Information Packet publication that shipped with your router. Before you call, have the following information ready:

Chassis type and serial number
Maintenance agreement or warranty information
Type of software and version number
Date you received the new chassis
Brief description of the problem
Brief explanation of the steps you have taken to isolate the problem

Problem Solving

The key to problem solving is to isolate the problem to a specific subsystem by comparing what the router is doing to what it should be doing.

The LEDs on the front and rear panel of the router enable you to determine router performance and operation. For a description of these LEDs, see the following:

When problem solving, consider the following router subsystems:

Power and cooling systems---External power source, power cable, router power supply and circuit breaker, and router blower and fan. Also consider inadequate ventilation or air circulation.
Modules---LEDs on the modules help identify a failure.
Cables---External cables that connect the router to the network.

Troubleshooting the Po wer and Cooling Systems

Both the system LED and the fans can help you troubleshoot a power problem. Check the following items to help isolate the problem:

With the power switch on, does the system LED stay on or blink?
- If the LED is green, the router is receiving power and is functional.
- If the LED is amber, the router is receiving power but is not functional.
- If the LED is off, check the power source and power cable.
With the power switch on and the system LED on, do the fans operate?
- If no, check the fans.
With the power switch on and the system LED off, do the fans operate?
- If yes, the router is receiving power. The fans are connected directly to the DC outputs of the power supply.
- If no, check the power source and power cable.
Does the router shut down after being on a short time?
- Check for an environmentally induced shutdown. See the next section, "Environmental Reporting Features."
- Check the environmental site requirements in the "General Site Requirements" section.
- Check for a power supply failure in the Cisco 3620 and Cisco 3640 routers by inspecting the system LED on the front panel. If the system LED is on or blinking, the power supply should be functional.
- Check for a power supply failure in the Cisco 3660 router by inspecting the system, PS1, and PS2 LEDs on the front panel. If they are green, the power supplies are functional.
Router partially boots, but LEDs do not go on.
- Check for a power supply failure by inspecting the system LED on the front panel of the router. If the system LED is on, the power supply is functional.
- Check for a power supply failure in the Cisco 3660 router by inspecting the PS1 and PS2 power supply LEDs on the front panel. For an explanation of these LEDs, see Table A-3.
- If the system LED is not on, refer to the Cisco Information Packet for warranty information or contact customer service.

Environmental Reporting Features

If the router is operating at an abnormally high temperature, you see the following message on the console screen:

%SYS-1-OVERTEMP: System detected OVERTEMPERATURE condition. Please resolve cooling problem immediately!

Some causes of abnormally high router temperature are:

Fan failure
Air conditioner failure in the room
Air blockage to cooling vents

Take steps to correct the problem. See also the "Site Environment" section, and the "Equipment Racks" section.

Troubleshooting Modules, Cables, and Connections

Network problems can be caused by a module, cables or cable connections, or external devices such as a modem, transceiver, hub, wall jack, WAN interface, or terminal. Check for the following symptoms to help isolate the problem:

Module is not recognized by the router.
- On the Cisco 3660 router, check front-panel Active and Ready LEDs for the slot in which the module is installed. For information on these LEDs, see the "Reading Front-Panel LEDs" section.
- Make sure the module is firmly seated in its slot.
- Check the LEDs on the module. Each module has its own set of LEDs. For information on these LEDs, see the publication Cisco Network Modules Hardware Installation Guide.
- Make sure you have a version of Cisco IOS software that supports the module. Check the Software Configuration Guide or accompanying configuration note for the affected module's software requirements.
Module is recognized, but interface ports do not initialize.
- Make sure the module is firmly seated in its slot.
- Check external cable connections.
- Make sure you have a version of Cisco IOS software that supports the module. Check the configuration note for the affected module's software requirements.
Router does not boot properly, or constantly or intermittently reboots.
- Make sure the module is firmly seated in its slot.
- Check the router chassis or software. Refer to the Cisco Information Packet publication that shipped with your router for warranty information, or contact customer service.
Router boots, but the console screen is frozen.
- Check the external console connection.
- Verify that the parameters for your terminal are set as follows:
(a) The same data rate as configured for the router (9600 bps is the default)

(b) 8 data bits

(c) No parity generated or checked

(d) 2 stop bits
Router powers on and boots only when a particular module is removed.
- Check the module. Refer to the Cisco Information Packet publication that accompanied your order for warranty information, or contact customer service.
Router powers on and boots only when a particular cable is disconnected.
- There may be a problem with the module or cable. Refer to the Cisco Information Packet publication for warranty information, or contact customer service.
