3. Troubleshooting Functional Failures During Operation

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.

Adjust the transceiver to 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.

2Use the

show interfaces

command to display the

failure statistics for the

receiving side, and check

whether there are counts for

the following items for the

target port. If there is a

count, see the Cause and

Action columns.

• CRC errors

• Symbol errors

Line quality on

the receiving

side is degraded.

Check the type of the optical fiber. For the types, see the

Hardware Instruction Manual.

If an optical attenuator is used, check the attenuation value. For

the optical level, see the Hardware Instruction Manual.

Check the cable length. For the cable length, see the Hardware

Instruction Manual.
