Chapter 2 Alarm Troubleshooting

Alarm Procedures

2.7.256 UNEQ-V

Default Severity: Major (MJ), Service-Affecting (SA)

SONET Logical Objects: VT-MON, VT-TERM

An SLMF UNEQ VT alarm indicates that the node is receiving SONET path overhead with Bits 5, 6,

and 7 of the V5 overhead byte all set to zeroes. The source of the problem is not the node raising the

alarm, but the node transmitting the VT signal to it. The V in UNEQ-V indicates that the failure has

occurred at the VT layer.

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.

Statement 1057

Clear the UNEQ-V Alarm

Step 1 Complete the “Clear the UNEQ-P Alarm” procedure on page 2-151.

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

or ONS 15310-MA.

Step 2 If the alarm 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) in order to report a Service-Affecting (SA)

problem.

2.7.257 UNQUAL-PPM

Default Severity: Not Reported (NR), Non-Service-Affecting (NSA)

SONET Logical Objects: PPM

The Unqualified PPM Inserted condition occurs when a PPM with a nonqualified product ID is plugged

into the card’s port; that is, the PPM passes the security code check as a Cisco PPM but is not qualified

for use on the particular card.

Clear the UNQUAL-PPM Condition

Step 1 Obtain the correct Cisco PPM and replace the existing PPM with the new one.
