Chapter 2 Alarm Troubleshooting

Alarm Procedures

Clear the RFI-V Condition

Step 1 Verify that the fiber connectors are securely fastened and connected to the correct slot. For more

information, refer to the “Install Hardware” chapter in the Cisco ONS 15310-CL and

Cisco ONS 15310-MA Procedure Guide.

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15310-CL

or ONS 15310-MA.

Step 2 If connectors are correctly connected, verify that the port is active and in service (IS-NR) by completing

the following steps:

a. Confirm that the green ACT LED is on.

b. Double-click the 15310-CL-CTX or CTX2500 card in CTC to display the card view.

c. Click the Provisioning > Optical > Line tabs.

d. Verify that the Admin State column lists the port as IS.

e. If the Admin State column lists the port as OOS,MT or OOS,DSBLD, click the column and choose

IS. Click Apply.

Note If ports managed into IS administrative state are not receiving signals, the LOS alarm is

either raised or remains, and the port service state transitions to OOS-AU,FLT.

Step 3 If the ports are active and in service, use an optical test set to verify that the signal source does not have

errors. For specific procedures to use the test set equipment, consult the manufacturer.

Step 4 If the signal is valid, log into the node at the far-end of the reporting ONS 15310-CL or ONS 15310-MA.

Step 5 Clear alarms in the far-end node, especially the “UNEQ-P” alarm on page 2-151 or the “UNEQ-V” alarm

on page 2-153.

Step 6 If the condition does not clear, log into the Technical Support Website at

http://www.cisco.com/techsupport for more information or call Cisco TAC (1-800-553-2447).

2.7.201 ROLL

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

SONET Logical Objects: STSMON, STSTRM, VT-MON, VT-TERM

The ROLL condition indicates that circuits are being rolled. This is typically done to move traffic for a

maintenance operation or to perform bandwidth grooming. The condition indicates that a good signal

has been received on the roll destination leg, but the roll origination leg has not yet been dropped. The

condition clears when the roll origination leg is dropped.

Note ROLL is an informational condition and does not require troubleshooting.
