Chapter 2 Alarm Troubleshooting
Alarm Procedures
DWDM Logical Object: PPM
The Equipment High Laser Optical Transceiver Temperature alarm applies to the STM-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 (STM)” alarm on
page 2-98 is raised at the far-end node and the “DUP-IPADDR” alarm on page 2-47 is raised at the near
end.
Clear the HI-LASERTEMP Alarm
Step 1 In node view, double-click the controller card (ONS 15310-MA SDH) 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 2-151 for
the card.
Step 5 If the alarm does not clear, complete the “Physically Replace a Card” procedure on page 2-153 for the
card.
Caution Always use the supplied electrostatic discharge wristband when working with a powered
ONS 15310-MA SDH.
Step 6 If the alarm 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).
2.7.94 HI-RXPOWER
Default Severity: Minor (MN), Non-Service-Affecting (NSA)
SDH Logical Object: STM
The Equipment High Receive Power alarm is an indicator for STM port received optical signal power.
HI-RXPOWER occurs when the measured optical power of the received signal falls under the threshold.
The threshold value is user-provisionable.
Clear the HI-RXPOWER Alarm
Step 1 Complete the “Clear the LO-RXPOWER Alarm” procedure on page 2-92.
Step 2 If the alarm 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).
