Chapter 5 Troubleshooting the Installation

Troubleshooting Overview

•Cooling subsystem—The chassis fan tray is the single component in this subsystem. The fans should be operating whenever system power is on. Replace the fan tray if you determine a fan is not functioning properly.

•Processor subsystem—This subsystem includes the I/O controller, network processing engine (NPE) or network services engine (NSE), the Port Adapter Jacket Card, and all port or service adapters. The system memory and management functions reside on the I/O controller and the network processing engine or network services engine. The enabled LED on each port adapter indicates if the port adapter is initialized. A port adapter that is partially installed in the midplane can cause the system to hang and crash.

The following sections help you isolate a problem to one of these subsystems and direct you to the appropriate troubleshooting section.

Identifying Startup Problems

Note When powering on or powering off the router, wait 30 seconds before powering it on or powering it off again.

Startup problems are commonly due to the source power or to a board (network processing engine or network services engine, I/O controller, or port or service adapter) that is dislodged from the midplane. Although an overtemperature 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 on page 4-2in Chapter 4, “Observing System Startup and Performing a Basic Configuration.” This section contains a more detailed description of the normal startup sequence and describes the steps to take if the system does not perform that sequence as expected.

With the exception of the fan tray and network processing engine or network services engine, 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.

Fans Operating

You should immediately hear the fans operating. If not, proceed to the “Troubleshooting the Cooling Subsystem” section on page 5-10. If you determine that the power supply is functioning normally and that a fan is faulty, contact a customer service representative. If a fan does not function properly at initial startup, there are no installation adjustments that you should make.

Power LEDs

The green power OK LED (at the rear of the chassis) should come on immediately when you place the power supply switch in the on () position, and remain on during normal system operation.

If the green power OK LED does not come on, proceed to the “Troubleshooting the Processor

Subsystem” section on page 5-7.
