Airflow direction
The airflow direction for Avaya Virtual Services Platform 8200 and Avaya Virtual Services Platform
8400 is front-to-back.
Installing a fan module
The Avaya Virtual Services Platform 8000 Series comes with four 12–V fan modules for switch
cooling.
Figure 24: Fan module
There are four sensors inside the chassis that monitor the temperature. These sensors send
information to a controller that automatically regulates the fan speed to maintain the proper
temperature.
•
If any sensor exceeds its threshold, an alarm is triggered and the log is generated in the
format:
Temperature Sensor [CPU | MAC | PHY1 | PHY2] is ([value] C) has exceeded the alarm
threshold temperature ([value] C)
Important:
The system does not shutdown when it exceeds the threshold temperature.
• When the temperature cools by 2° below the threshold, the alarm clears and the log is
generated in the format:
Temperature Sensor [CPU | MAC | PHY1 | PHY2] overheat temperature alarm cleared
The following table shows the types of sensors and the corresponding threshold values:
CPU MAC PHY1 PHY2
55
Important:
When the CPU
temperature
exceeds this
threshold it does not
trigger any alarm.
60
Important:
When the MAC
temperature
exceeds this
threshold it does not
trigger any alarm.
60 60
Use this procedure if a fan fails and you have to replace it.
