Warning Before you install, operate, or service the system, read the Site Preparation and Safety Guide. This guide contains important safety information you should know before working with the system. |
 |
Note The information in this chapter applies to all Catalyst 5000 family switches unless otherwise noted. |
This chapter describes how to troubleshoot the Catalyst 5000 family switch hardware installation:
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, environmental monitoring functions are included because they also monitor DC-line voltages.
|
Note This chapter covers only the chassis component hardware aspects of troubleshooting. For module-specific information, refer to the Catalyst 5000 Family Module Installation Guide. For supervisor engine-specific information, refer to the Catalyst 5000 Family Supervisor Engine 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 Software Configuration Guide and Command Reference publication for your switch 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.
|
Note The Catalyst 5002 power supplies and fan assembly are not field-replaceable units (FRUs). |
The switch consists of the following subsystems:
|
Note Catalyst 5505, Catalyst 5509, and Catalyst 5500 switches—If you have a redundant supervisor engine, see Chapter 3, "Configuring the Supervisor Engine," in the Catalyst 5000 Family Supervisor Engine Installation Guide. This chapter describes how the redundant supervisor engines come online and how the software images are handled. |
When you start the switch for the first time, follow the startup procedure in Chapter 3, "Configuring the Supervisor Engine," in the Catalyst 5000 Family Supervisor Engine Installation Guide. The startup procedure contains a detailed description of the normal startup sequence and describes what to do if the system does not perform the sequence as expected.
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 (or connect the power cords to the Catalyst 5002 switch), follow these steps:
Catalyst 5002 switch—The fan assembly is not an FRU. If the fan is not operating, shut down the system immediately and contact your customer service representative.
Step 2 Check that the power supply LEDs on the supervisor engine at the left of the chassis light as follows:
Catalyst 5002—The power supplies are not FRUs. If the power supply LEDs on the supervisor engine do not light, contact your customer service representative.
Step 3 Check that the LEDs on the supervisor engine light as follows:
|
Note Catalyst 5505, Catalyst 5509, and Catalyst 5500 switches—If you have a redundant supervisor engine, see Chapter 3, "Configuring the Supervisor Engine," in the Catalyst 5000 Family Supervisor Engine Installation Guide. The section describes how the redundant supervisor engines come online and how the software images are handled. |
If any LEDs on the supervisor engine front panel are red or orange, see the "Troubleshooting Modules" section.
Step 4 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. However, 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 5 If the boot information and system banner are not displayed, see Chapter 3, "Installing the Supervisor Engine," in the Catalyst 5000 Family Supervisor Engine Installation Guide to verify that the terminal is set correctly and that it is connected properly to the supervisor engine console port.

Note The Catalyst 5002 power supplies are not FRUs. |
|
Note The Catalyst 5500 power supply LED is red when no modules are installed. |
To help isolate a power subsystem problem, follow these steps:
|
Note This procedure assumes that only one power supply is installed in the switch chassis, and that it is installed in the left bay. |
|
Note If this unit has more than one power cord, repeat Step 1 for each power supply. |
Step 2 Check if the PS2 LED for the second (redundant) power supply is on.
|
Note This step assumes two power supplies are installed in the switch chassis. |
|
Note The Catalyst 5002 fan assembly is not an FRU. |
To help isolate a fan assembly problem, follow these steps:
Step 2 Check if the FAN LED is still red.
If it is red, this indicates that the system detects a fan assembly failure. Contact a customer service representative for instructions.
To help isolate a supervisor engine or switching module problem, check the following items:
Step 2 Check if any STATUS LEDs on the supervisor engine or any switching modules are red.
If you still experience trouble with the startup, contact a customer service representative for assistance.
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.
