Alarm Procedures
Clear the OOT-TPT Condition
Step 1 Complete the “Clear the VCG-DEG Condition” procedure on page 2-144. Clearing that condition clears
this condition as well.
Step 2 If the condition does not clear, log into the Technical Support Website at
http://www.cisco.com/cisco/web/support/index.html for more information or call Cisco TAC
(1-800-553-2447).
2.7.170 OPEN-SLOT
Default Severity: Not Alarmed (NA)
SDH Logical Object: EQPT
The Open Slot condition indicates that there is an open slot in the system shelf. Slot covers assist with
airflow and cooling.
Clear the OPEN-SLOT Condition
Step 1 To install a slot cover and clear this condition, refer to the procedures located in the “Install Hardware”
chapter of the Cisco ONS15310-MA SDH Procedure Guide.
Step 2 If the condition does not clear, log into the Technical Support Website at
http://www.cisco.com/cisco/web/support/index.html for more information or call Cisco TAC (1 800
553-2447).
2.7.171 LP-PLM
Default Severity: Critical (CR), Service-Affecting (SA)
SDH Logical Objects: VCMON-HP, VCTRM-HP
A Payload Label Mismatch Path alarm indicates that signal does not match its label. The condition is
indicated by an invalid C2 byte value in the SDH path overhead.
This alarm can occur on a 15310-MA-CTX, E1-21/DS3-E3-3, or E1-63/DS3-E3-3 card when it expects
a E1 signal but receives a DS-3 signal. The DS-3 signal C2 byte value is 4, so this causes a label
mismatch and a LP-PLM alarm.
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.
