Troubleshooting

Overview

Overview

This chapter addresses performance-related network problems that can be caused by topology, switch configuration, and the effects of other devices or their configurations on switch operation. (For switch-specific information on hardware problems indicated by LED behavior, cabling requirements, and other potential hardware-related problems, refer to the installation guide you received with the switch.)

HP periodically places switch software updates on the HP ProCurve web site. HP recommends that you check this web site for software updates that may have fixed a problem you are experiencing.

For information on support and warranty provisions, see the Support and Warranty booklet shipped with the switch.

Troubleshooting Approaches

Use these approaches to diagnose switch problems:

Check the HP ProCurve web site – the web site may have software updates or other information to help solve your problem:

Check the switch LEDs – The LEDs on the switch are a fundamental diagnostic tool. They provide indications of proper switch operation and of any hardware faults that may have occurred:

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.
