Note The information in this chapter applies to all Catalyst 6000 family switches unless otherwise noted. |
This chapter describes how to troubleshoot the Catalyst 6000 family switch hardware installation and contains these sections:
If your system has problems starting up, use the information in this chapter to help isolate the cause. Problems with the initial startup are often caused by a switching module that has become dislodged from the backplane or a power supply that has been disconnected from the power cord connector. Although temperature conditions above the maximum acceptable level rarely occur at initial startup, these conditions may be encountered during extended operation. Long-term monitoring functions also include independent reporting of DC-output voltage problems.

Note This chapter covers only the chassis component hardware aspects of troubleshooting. For module-specific information, refer to the Catalyst 6000 Family Module Installation Guide. |
When the initial system boot is complete, verify the following:
If each of these conditions is met and the hardware installation is complete, refer to the Catalyst 6000 Family Software Configuration Guide or Catalyst 6000 Family IOS Software Configuration Guide and the Catalyst 6000 Family Command Reference or Catalyst 6000 Family IOS Command Reference publications to troubleshoot the software. However, if any of these conditions are not met, use the procedures in this chapter to isolate and, if possible, resolve the problem.
The key to success when troubleshooting the system is to isolate the problem to a specific system component. The first step is to compare what the system is doing to what it should be doing. Because a startup problem can usually be attributed to a single component, it is more efficient to isolate the problem to a subsystem rather than troubleshoot each separate component in the system.
The switch consists of the following subsystems:
LEDs indicate all system states in the startup sequence. By checking the LEDs, you can determine when and where the system failed in the startup sequence.
When you turn the power supplies on, the following should occur:
Step 2 Check that the LEDs on the supervisor engine light as follows:
If any LEDs on the supervisor engine front panel are red or orange, see the "Troubleshooting Modules" section.
If you have a redundant supervisor engine, refer to the Catalyst 6000 Family Software Configuration Guide or Catalyst 6000 Family IOS Software Configuration Guide publications for descriptions of how the redundant supervisor engine comes online and how the software images are handled.
For a complete description of the supervisor engine LEDs, refer to the Catalyst 6000 Family Module Installation Guide.
Step 3 Verify that the STATUS LEDs on the supervisor engine and on each switching module are green when the supervisor engine completes initialization. This LED indicates that the supervisor engine or switching modules are receiving power, have been recognized by the supervisor engine, and contain a valid Flash code version. This LED does not indicate the state of the individual interfaces on the switching modules. If a STATUS LED is red or orange, see the "Troubleshooting Modules" section.
Step 4 If the boot information and system banner are not displayed, refer to the Catalyst 6000 Family Module Installation Guide to verify that the terminal is set correctly and that it is connected properly to the supervisor engine console port.
Perform these steps to help isolate a power subsystem problem:
If this unit has more than one power cord, repeat Step 1 for each power supply.
If the INPUT OK LED still fails to light when the switch is connected to a different power source with a new power cord, the power supply is probably faulty.
If a second power supply is available, install it in the second power supply bay and contact a customer service representative for further instructions.
Step 2 If you have a second (redundant) power supply, repeat Step 1 for this power supply.
If you are unable to resolve the problem, or if you determine that either a power supply or backplane connector is faulty, see the "Contacting Customer Service" section.
Perform these steps to help isolate a fan assembly problem:
If it is not, see the "Problem Solving to the System Component Level" section to determine whether the power subsystem is functioning properly.
Step 2 Check if the FAN LED is red.
Check the following items to help isolate a supervisor engine or switching module problem:
If the status LED on a switching module is orange, the module might be busy or disabled. Refer to the Catalyst 6000 Family Software Configuration Guide or Catalyst 6000 Family IOS Software Configuration Guide publications and the Catalyst 6000 Family Command Reference or Catalyst 6000 Family IOS Command Reference publications to configure or enable the interfaces. After the system reinitializes the interfaces, the status LED on the module should be green.
If you still experience trouble with the startup, see the "Contacting Customer Service" section.
If you are unable to solve a startup problem after using the troubleshooting suggestions in this chapter, contact a customer service representative for assistance and further instructions. Before you call, have the following information ready to help your service provider assist you as quickly as possible:
