Install a Fan Module
The VSP 7200 Series comes with three 12–V fan modules for either front-to-back or back-to-front air
flow switch cooling.
Important:
Make sure the air flow direction of your power supplies matches the same direction for your fan
modules.
Refer to the following part numbers to ensure that you install the correct fan modules in your
switch. Both the VSP 7254XSQ (fiber switch) and the VSP 7254XTQ (copper switch) use the
same fan module models:
• EC7200BTF-E6 — 12 V BACK2FRONT SPARE FAN MODULES (INC 3 FAN MODULE
KITS)
• EC7200FTB-E6 — 12 V FRONT2BACK SPARE FAN MODULES (INC 3 FAN MODULE
KITS)
There are 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 | MAC1 | MAC2]
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 | MAC1 | MAC2]
overheat temperature alarm cleared
There are three sensors in VSP 7254XSQ. The following table shows the types of sensors and the
corresponding threshold values:
