Troubleshooting Approaches

Check the network cables – Cabling problems are a frequent cause of network faults. Check the cables for damage, correct type, and proper connections. You should also use a cable tester to check your cables for compliance to the relevant IEEE 802.3 specification. See the Installation Guide shipped with the switch for correct cable types and connector pin- outs.

Use the software tools:

Web Browser Interface – Use the Port Utilization Graph and Alert Log in the web browser interface included in the switch to help isolate problems. See Chapter 5, “Using the HP Web Browser Interface” for operating information. These tools are available through the web browser interface:

Port Utilization Graph

Alert Log

Port Status and Port Counters screens

Diagnostic tools (Link test, Ping test, configuration file browser)

Switch Console – For help in isolating problems, use the easy-to- access switch console built into the switch or Telnet to the switch console. See chapter 2, “Using the Menu Interface” and chapter 3, “Using the Command Line Interface (CLI)” for console operation information. These tools are available through the switch console:

Status and Counters screens

Diagnostics tools (Link test, Ping test, configuration file browser, and advanced user commands)
