10. Troubleshooting

This chapter contains procedures that help you troubleshoot problems with a CrossFire 8600 Token-Ring Switch or a CrossFire 8605 Token-Ring Fiber Switch and its connections to other devices.

Obtaining Service

There are no serviceable parts inside the switch. Do not remove the cover for any reason. If you think your switch or its UEMs requires service, please contact Olicom Technical Support. Please refer to Chapter 11, “Getting in Touch with Technical Support” for instructions.

Troubleshooting in a Network

The switch console and SNMP management agent give you access to important statistics and other information about the network, as seen by the switch. (See Chapter 7, “Monitoring the Network with the Console”).

The section “Port Statistics Menu” on page 152 can be helpful in isolating network level problems.

The Switched Port Analyzer feature allows a network analyzer to be attached to a port on the switch to monitor, in real time, switch activity of another port. See Chapter 9, “Monitoring Port Traffic” for information on configuring Switched Port Analyzer.

Start of Troubleshooting Process

If one or more devices (such as PCs) connected to a switch are unable to communicate with other devices in the network, use the following steps to start the troubleshooting process:

1.Locate the switch to which the device is connected. Use the network sketch, the label on the cable connected to the device, or other network records to help you locate the switch.

2.If you have an UEM and the problem is related to it, use its documentation to assist in troubleshooting.

3.If you have set up a console session (see Chapter 5, “Connecting a Network Management Console”), it can be used to determine whether diagnostics have been completed correctly. A list of normal diagnostic messages is shown on page 72.
