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.)
N o t e 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:
http://www.hp.com/go/hpprocurve
■ 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.
