Your Cisco 7100 series router went through extensive testing before leaving the factory. However, if you encounter problems starting the router, use the information in this chapter to help isolate the cause of the problems. This chapter contains the following sections:
The procedures in this chapter assume that you are troubleshooting the initial system startup, and that your router is in the original factory configuration. If you have removed or replaced components or changed any default settings, the recommendations in this chapter might not apply. Make sure to review the safety warnings listed in the publication Regulatory Compliance and Safety Information for Cisco 7100 Series VPN Routers that accompanied your Cisco 7100 series router before using the troubleshooting procedures in this chapter.
Figure 5-1 shows the general troubleshooting strategy described in this chapter. Refer to this chart, as necessary, to follow the steps to isolate problems to a specific subsystem; then resolve the problem if possible.
If you are unable to easily solve the problem, contact a customer service representative for assistance and further instructions. Provide the representative with the following information:
The key to solving problems with the system is isolating the problem to a specific subsystem. The first step in solving startup problems is to compare what the system is doing to what it should be doing. Because a startup problem is usually caused by a single component, it is more efficient to first isolate the problem to a subsystem rather than troubleshoot each component in the system. For these troubleshooting procedures, consider the following subsystems:
The following sections help you isolate a problem to one of these subsystems and direct you to the appropriate troubleshooting section.
Startup problems are commonly due to the source power or to a port adapter that is dislodged from the router. Although an over temperature condition is unlikely at initial startup, the environmental monitoring functions are included in this chapter because they also monitor internal voltages.
When you start up the router for the first time, you should observe the startup sequence described in the "Starting the System and Observing Initial Conditions" section, which contains a more detailed description of the normal startup sequence.
LEDs indicate all system states in the startup sequence. By checking the state of the LEDs, you can determine when and where the system failed in the startup sequence. Use the following descriptions to isolate the problem to a subsystem, and then proceed to the appropriate sections to try to resolve the problem.
When you start up the system by turning the power supply switch to the on (|) position, the following should occur:
Check the following to help isolate a problem with the power 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.
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), check the following items to help isolate the problem:
Check the following to help isolate a problem with a port adapter or fixed WAN port:
Check the following to help isolate a problem with the cooling system:
Queued messages: 00:01:19:%ENVM-4-ENVWARN:+2.5 V measured at +2.59 00:01:19:%ENVM-4-ENVWARN:+5.15 V measured at +5.31 00:00:19:%ENVM-2-ENVCRIT:chassis core measured at 31C/87F 00:00:19:%ENVM-2-ENVCRIT:chassis inlet measured at 27C/80F 00:00:19:%ENVM-2-ENVCRIT:chassis outlet 1 measured at 30C/86F 00:00:19:%ENVM-2-ENVCRIT:chassis outlet 2 measured at 30C/86F
Although an overtemperature condition is unlikely at initial startup, ensure that heated exhaust air from other equipment is not entering the router's inlet vent, and that there is sufficient clearance around the sides of the chassis to allow cooling air to flow. (See the "Site Requirement Guidelines" section for preventive site configurations.)
The above message could also indicate a faulty component or temperature sensor. Use the show environment or show environment table command to display the internal chassis environment. (See the "Displaying Environmental Status Reports" section for descriptions of the show environment and show environment table commands.)
If you experience trouble with the startup that is not resolved with these procedures, manually power off the router and contact a service representative for assistance and
further instructions.
