Troubleshooting the Installation

Troubleshooting the Installation

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:

• Getting Started
  
  
• Problem Solving to the System Component Level
  
  
• Identifying Startup Problems
  
  
• Troubleshooting the Power Supply
  
  
• Troubleshooting the Fan Assembly
  
  
• Troubleshooting Modules
  
  
• Contacting Customer Service
  
  

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.

Getting Started

When the initial system boot is complete, verify the following:

• Power supplies are supplying power to the system.
  
  
• The system fan assembly is operating.
  
  
• System software boots successfully.
  
  
• The supervisor engine and all switching modules are installed properly in their slots, and each was initialized without problems.
  
  

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.

Problem Solving to the System Component Level

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:

• Power supply—Includes the power supplies and power supply fans.
  
• Fan assembly—The chassis fan assembly should operate whenever system power is on. Usually, it continues to operate even when the environmental monitor shuts down the system because of an overtemperature or overvoltage condition (although it will shut down in the event of a power supply shutdown). You should be able to hear the fan assembly to determine whether or not it is operating. If the FAN LED is orange and you determine that the fan assembly is not operating, you should immediately contact a customer service representative. There are no installation adjustments that you can make if the fan assembly does not function properly at initial startup.
  
• Supervisor engine—The supervisor engine contains the system operating software, so check here if you have trouble with the system software. Status LEDs on the supervisor engine indicate whether or not the supervisor engine is able to initialize the switching module.

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.

---

• Switching modules—The STATUS LEDs on each switching module indicate whether or not the switching module has been initialized by the supervisor engine. A switching module that is partially installed in the backplane causes the system to halt.
  
  

Identifying Startup Problems

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:

• If you do not immediately hear the system fan assembly begin to operate, see the "Troubleshooting the Power Supply" section.
  
  
• If you determine that the power supplies are functioning normally and that the fan assembly is faulty, contact a customer service representative.
  
  
• If the system fan assembly does not function properly at initial startup, there are no installation adjustments that you can make. To replace the fan assembly, see "Removal and Replacement Procedures."
  
  

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:

• The PS1 or PS2 LED on the supervisor engine should turn green immediately when power is applied to the system. The LEDs should remain on during normal system operation.
  
• If the appropriate PS1 or PS2 LED does not light, see the "Troubleshooting the Power Supply" section.
  
  

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.

• The SYSTEM STATUS LED flashes orange once and stays orange during diagnostic boot tests. It turns green when the module is operational (online). If the system software is unable to start up, this LED stays orange.
  
  
• Each LINK LED flashes orange once, stays orange during diagnostic boot tests, and turns green when the module is operational (online). If no signal is detected, the LINK LED turns off. The LINK LED blinks orange if the port is bad.
  
  
• The FAN LED should always be green. This LED is orange if the system detects a fan failure and red if the fan is not operational.
  
  

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.

Troubleshooting the Power Supply

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.

• If the appropriate LED is on, the AC or DC source is good and the power supply is functional.
  
  
• If the appropriate LED is off, first ensure that the power supply is flush with the back of the chassis. Turn the power switch off, tighten the captive installation screws, and then turn the power switch on.
  
  
  • If the appropriate LED remains off, there might be a problem with the AC source, the DC circuit, or the power cable.
    
    

  Turn off the power to the switch, connect the power cord to another power source if one is available, and turn the power on.
  

  If the appropriate LED then lights, the problem is the first power source.
  

  • If the LED fails to light after you connect the power supply to a new power source, replace the power cord, and turn the switch on.
    
    

  If the LED then goes on, return the first power cord for replacement.
  

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.

• If the PS2 LED is not on, repeat the previous procedure to troubleshoot the second power supply.
  
  
• If you are unable to resolve the problem, or if you determine that either a power supply or backplane connector is faulty, contact a customer service representative for instructions.
  
  

Troubleshooting the Fan Assembly

Note   The Catalyst 5002 fan assembly is not an FRU.

To help isolate a fan assembly problem, follow these steps:

• If it is not, see the "Problem Solving to the System Component Level" section to determine whether the power subsystem is functioning properly.
  
  
• If it is red, the fan assembly is not seated in the backplane or has malfunctioned.
  
  

  To ensure that the fan assembly is seated properly, loosen the captive installation screws, remove the fan assembly, and reinstall it.

  Tighten all captive installation screws, and then restart the system.

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.

Troubleshooting Modules

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 the LEDs are on, the module might have shifted out of its slot.
  
  

  Reseat the module until both ejector levers are at a 90-degree orientation to the rear of the chassis. Tighten the captive installation screws at the left and right of the module front panel, and restart the system.

• If the STATUS LED on a switching module is red, the module might be busy or disabled. Refer to the Software Configuration Guide and the Command Reference publication for your switch 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, contact a customer service representative for assistance.
