3. Troubleshooting Functional Failures During Operation
40
Check the cable length. For the cable length, see the Hardware
Instruction Manual.
Check whether the cables are connected correctly (for
example, check for incomplete insertion). Make sure that the
end sections of the cables are clean. If they are dirty, clean
them.
Check whether the transceiver is connected correctly.
For the
speed and duplex configuration commands, specify
the same values that are on the remote device.
Comply with the segment standard of the remote device.
Check whether the optical level is correct. For the optical level,
see the Hardware Instruction Manual.
Perform a line test on the Switch and make sure that the
functionality of the receiving side has no problem. Check the
results of the
no test interfaces command, and take the
action described in Action. For the test types to be specified,
see 6.1 Testing a line.
3 For AX3800S, AX3600S,
or AX2400S series
switches, use the
show
interfaces command to
display the failure
statistics, and check
whether there is a count for
the following item for the
target port. If there is a
count, see the Cause and
Action columns.
• TX fault
The transceiver
has failed.
Replace the transceiver.
4 If a single-core optical
fiber cable such as
1000BASE-BX is used,
make sure that the
transceiver of the Switch is
suitable to use with the
remote transceiver.
The combination
of the
transceivers is
incorrect.
If 1000BASE-BX is used, one side must use a U-type
transceiver and the other side must use a D-type transceiver.
Check whether the transceiver types are correct.
5 If 100BASE-FX is used,
execute the
show
interfaces command
and check the line type and
line speed in the detail
information displayed for
the target port. If the line
type or speed is invalid,
see the Cause and Action
columns.
The values
specified for the
speed and
duplex
configuration
commands are
different from
those on the
remote device.
For the
speed and duplex configuration commands, specify
the same values that are on the remote device.
