Default Severity: Critical(CR), Service-Affecting (SA) for NE; Default Severity: Minor (MN),
Non-Service-Affecting(NSA) for EQPT
SONET Logical Objects: EQPT, NE
The High Temperature alarm occurs when the temperature of the ONS15310-CL or ONS 15310-MA is
above 122degrees F (50 degrees C).

Clear the HITEMP Alarm

Step1 Verify that the environmental temperature of the room is not abnormally high.
Step2 If the room temperature is not abnormal, physically ensure that nothing prevents the internal
ONS 15310-CL or ONS 15310-MA fan from passing air through the ONS 15310-CL or ONS 15310-MA
shelf.
Step3 Ensure that any empty chassis slots are covered with filler cards. These aid in airflow management.
Step4 If the alarm persists, log into the Technical Support Website at http://www.cisco.com/techsupport for
more information or call CiscoTAC to report a Service-Affecting (SA) problem (1-800-553-2447) if it
applies to the NE, or a Non-Service-Affecting(NSA) problem if it applies to equipment.
