CrossFire 8600/8605 Token-Ring Switches v. 1.2, P/N: 710001641 Troubleshooting
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.
