10/100 Ethernet LAN Port Tests
A loopback plug is required to run the first part of the Ethernet LAN test. See
“Loopback Plugs for Testing Switch Interfaces” on page 25 for details of how to
make a loopback plug. To start an Ethernet interface test, use the command:
ENABLE TEST INT=PORTn
where n is the Ethernet interface number. The test will run for 4 minutes. Use
the show test command to observe the test progress.
Other Interface Tests
Refer to the Test Facility chapter of the Software Reference for information on
testing other interfaces. If a test fails, please contact your Authorised Allied
Telesis distributor or reseller.
Troubleshooting
This section provides information on how to detect and resolve problems with
the Rapier Switch and its expansion options.
Other sources of useful troubleshooting information are:
■ www.alliedtelesis.com/support/software.
■ The Rapier Switch Software Reference.
Performing the following tasks will eliminate the most common faults.
1. Make sure the power cord is securely connected.
2. Check that the power supply voltage is stable.
3. Check that the correct data cables are being used and that their connections
are secure.
4. Make sure that other network devices are working properly.
5. Use the SHOW INSTALL command to check that the latest software version
is loaded. See the Rapier Switch Software Reference for more information
about obtaining the latest software version.
6. If the switch is malfunctioning, reboot it by pressing the recessed Reset
button or entering the command RESTART REBOOT. Alternatively, power
OFF and ON the switch by disconnecting and reconnecting the main power
supply (including, if connected, the RPS power).
