Table 82: HSC Backplane Temperature Sensor – Event Trigger Offset – Next Steps
Lower non critical
going low
The temperature has dropped below its lower non
critical threshold.
1. Check for clear and unobstructed airflow into and out of
chassis.
2. Ensure SDR is programmed and correct chassis has
been selected.
3. Ensure there are no fan failures.
4. Ensure the air used to cool the system is within the
thermal specifications for the system (typically below
35°C).
The temperature has dropped below its lower critical
threshold.
Upper non critical
going high
The temperature has gone over its upper non critical
threshold.
Upper critical
going high
The temperature has gone over its upper critical
threshold.
14.2 HSC Drive Slot Status Sensor
The HSC Drive Slot Status sensor will provide the current status for drives in each of the slots.
