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

2.7.108 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 2-106 is raised at the far-end node and the “DUP-IPADDR” alarm on page 2-50 is raised at the near
end.
Clear the HI-LASERTEMP Alarm
Step 1 In node view, double-click the controller card (15310-CL-CTX or CTX2500 card) to display the card
view.
Step 2 Click the Performance > Optics PM tabs.
Step 3 Verify the card laser temperature levels. Maximum, minimum, and average laser temperatures are shown
in the Current column entries in the Laser Temp rows.
Step 4 Complete the “Soft- or Hard-Reset an Ethernet or Electrical Card in CTC” procedure on page 2-162 for
the card.
Step 5 If the alarm does not clear, complete the “Physically Replace a Card” procedure on page 2-163 for the
card.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15310-CL
or ONS 15310-MA.
Step 6 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport
