2.7.245 UNEQ-P
Step 5 If the Type column does not contain VTT, there are no VT tunnels connected with the alarm. Go to
Step 7.
Step 6 If the Type column does contain VTT, attempt to delete these rows by completing the following steps:
Note The node does not allow you to delete a valid VT tunnel or one with a valid VT circuit inside.
a. Click the VT tunnel circuit row to highlight it. Complete the “Delete a Circuit” procedure on
page 2-155.
b. If an error message dialog box appears, the VT tunnel is valid and not the cause of the alarm.
c. If any other columns contain VTT, repeat Step 6.
Step 7 If all ONS 15310-CL or ONS 15310-MA nodes in the ring appear in the CTC network view, determine
whether the circuits are complete by completing the following steps:
a. Click the Circuits tab.
b. Verify that PARTIAL is not listed in the Status column of any circuits.
Step 8 If you find circuits listed as incomplete, use an optical test set to verify that these circuits are not working
circuits that continue to pass traffic. For specific procedures to use the test set equipment, consult the
manufacturer.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15310-CL
or ONS 15310-MA.
Step 9 If the incomplete circuits are not needed or are not passing traffic, delete the incomplete circuits.
Complete the “Delete a Circuit” procedure on page 2-155.
Step 10 Recreate the circuit with the correct circuit size. Refer to the “Create Circuits” chapter in the
Cisco ONS 15310-CL and Cisco ONS 15310-MA Procedure Guide.
Step 11 Log back in and verify that all circuits terminating in the reporting port are active by completing the
following steps:
a. Click the Circuits tab.
b. Verify that the Status column lists all circuits as active.
Step 12 If the alarm does not clear, clean the far-end optical fiber according to site practice. If no site practice
exists, complete the procedure in the “Maintain the Node” chapter in the Cisco ONS 15310-CL and
Cisco ONS 15310-MA Procedure Guide.
Warning
Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector.
Do not stare into the beam directly with optical instruments. Viewing the laser output with certain
optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of
100 mm could pose an eye hazard.
Statement 1056
Warning
Use of controls, adjustments, or performing procedures other than those specified could result in
hazardous radiation exposure.
