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 and
Getting Started Guide you received with the switch.)
ProCurve periodically places switch software updates on the ProCurve web
site. ProCurve 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 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 and Getting Started Guide shipped with the
switch for a description of the LED behavior and information on using
the LEDs for troubleshooting.
Check the network topology/installation – See the Installation and
■
Getting Started Guide shipped with the switch for topology information.
