Troubleshooting Approaches

Use these approaches to diagnose switch problems:

Check the HP Procurve web site for software updates that may have solved your problem: http://www.hp.com/go/hpprocurve

Check the switch LEDs for indications of proper switch operation:

Each switch port has a Link LED that should light whenever an active network device is connected to 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 a description of the LED behavior and information on using the LEDs for trouble- shooting.

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. 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 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 4, “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)

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 Interface” 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)
