Chapter 2: Installing the EX2500 Ethernet Switch
Temperature Sensor Warning
Symptom: A temperature warning is displayed on the management console. 
Solution
1.
Make sure that the air circulation vents on the front and back of the switch are 
free from obstruction by cables, panels, rack frames, or other materials.
2.
Make sure that all cooling fans inside the switch are running. The FAN LED 
blinks to indicate a failure of one or more fans. 
3.
Use the following command to display fan status: 
show sys-info
If any fan stops during switch operation, contact Juniper Networks technical 
support.
4.
If necessary, cool the room to a lower temperature or provide a fan for greater 
air circulation.
