Cisco Systems 474, 274 manual Symptoms and Solutions

Chapter 5 Troubleshooting the System Hardware

Symptoms and Solutions

–Has this configuration ever worked?

–If it has been working, what changes were made before it failed?

–Is this the original reported failure?

•Hardware configuration

–Print (print screen) configuration currently in use

–BIOS level

•WAAS system software type and version level

To eliminate confusion, identical systems are considered identical only if they meet all these conditions:

•Are the exact machine type and models

•Have the same BIOS level

•Have the same adapters or attachments in the same locations

•Have the same address jumpers, terminators, and cabling

•Have the same WAAS software versions

•Have the same configuration options set in the system

•Have the same setup for the operating system control files

Comparing the configuration and software setup in working and nonworking systems might help to resolve the problem.
