Troubleshooting
Troubleshooting Approaches
■ Check the network cables – Cabling problems are a frequent cause of
network faults. Check the 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 the software tools:
• Web Browser Interface – Use the Port Utilization Graph and Alert
Log in the web browser interface included in the switch to help isolate
problems. See Chapter 5, “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)
• Switch Console – For help in isolating problems, use the easy-to-
access switch console built into the switch or Telnet to the switch
console. See chapter 2, “Using the Menu Interface” and chapter 3,
“Using the Command Line Interface (CLI)” for console operation
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)
• HP TopTools for Hubs & Switches – 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
your switch.
N o t e
Although TopTools recognizes the Switch 2626 as an SNMP device, custom­
ized device management is not supported for the Switch 2626 in HP TopTools
for hubs and switches.
