Troubleshooting Approaches

There are six primary ways to diagnose switch problems:

■Check the switch LEDs for indications of proper behavior:

•Each switch port has a Link LED that should light whenever an active network device is connected to a the port.

•Problems with the switch hardware and software are indicated by flashing the Fault and other switch LEDs.

See the Installation Guide shipped with the switch for information on using the switch LEDs for troubleshooting.

■Check the network topology/installation. See the Installation Guide shipped with the switch for topology information.

■Check cables for damage, correct type, and proper connections. See the Installation Guide shipped with the switch for cable types and connector pin-outs.

■Use HP TopTools for Hubs & Switches (if installed on your network) to help isolate problems and recommend solutions. HP TopTools is shipped at no extra cost with the switch.

■Use the Port Utilization Graph and Alert Log in the web browser interface included in the switch to help isolate problems. See chapter 3, “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 screen

•Port Counters screen

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

■For help in isolating problems, use the easy-to-access switch console built into the switch or telnet to the switch console. See chapter 4, “Using the Switch Console” for operating information. These tools are available through the switch console:

•Status and Counters screens

•Event Log

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