2.7.106 HI-LASERTEMP
Caution Removing a card that currently carries traffic on one or more ports can cause a traffic hit. To avoid this,
perform an external switch if a switch has not already occurred. See the “2.10.1 Protection Switching,
Lock Initiation, and Clearing” section on page2-147 for commonly used traffic-switching procedures.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS15310-CL
or ONS 15310-MA.
Note When you replace a card with the identical type of card, you do not need to make any changes
to the database.
Step2 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport
for more information or call CiscoTAC (1-800-553-2447).
2.7.106 HI-LASERTEMP
Default Severity: Minor(MN), Non-Service-Affecting (NSA)
SONET Logical Object: OCN
DWDM Logical Object: PPM
The Equipment High Laser Optical Transceiver Temperature alarm applies to the OC-N ports.
HI-LASERTEMP occurs when the internally measured transceiver temperature exceeds the card setting
by 35.6 degrees F (2 degrees C). A laser temperature change affects the transmitted wavelength.
When the card raises this alarm, the laser is automatically shut off. The “LOS (OCN)” alarm on
page 2-98 is raised at the far-end node and the “DUP-IPADDR” alarm on page2-45 is raised at the near
end.

Clear the HI-LASERTEMP Alarm

Step1 In node view, double-click the controller card (15310-CL-CTX or CTX2500 card) to display the card
view.
Step2 Click the Performance > Optics PM tabs.
Step3 Verify the card laser temperature levels. Maximum, minimum, and average laser temperatures are shown
in the Current column entries in the Laser Temp rows.
Step4 Complete the “Soft- or Hard-Reset an Ethernet or Electrical Card in CTC” procedure on page 2-153 for
the card.
Step5 If the alarm does not clear, complete the “Physically Replace a Card” procedure on page 2-154 for the
card.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS15310-CL
or ONS 15310-MA.
