— If it is not blinking and if the attached device is directly connected, it might
be set up incorrectly. Go to step 4.
If it is not blinking in a shared environment, check the segment cabling
and the media access unit.
— If the problem persists, try another identically configured port on the
switch. If the new port works there is a hardware problem with the failed
port. Obtain service. Contact your local Olicom representative.
3. Do the following:
— Using the SNMP manager, check to see whether the failing port is
disabled. If it is, enable it.
— If the port is not disabled, verify that your cables are wired correctly (see
"Cabling" on page 29).
— If the problem persist, disconnect the port cable. Try moving the cable to
another port until service can be arranged. If the switch can be temporarily
removed from service, connect a console and reset the switch with
diagnostics to see whether the port passes diagnostics and initializes. If it
does not, the problem is in the switch. In this case, contact technical
support as described in Chapter 6, "Getting in Touch with Technical
Support".
4. Restart the communication program on the failed connected device.
— If the communication program appears to start without errors, observe the
LINK LED and the ACT LED on the switch port. If LINK LED is on and
ACT LED is blinking, the problem may have gone away.
— If the problem persists, try another identically configured port on the
switch. If the new port works there is a problem with the failed port. Obtain
service. Contact your local Olicom representative.
5. The problem does not appear to be in the switch and the cables and devices
connected to the switch. The problem might be in the network applications or
other software running on the devices. See the software documentation for
software problem determination procedures, or consult your network
administrator for assistance.
