Extracting and Inserting the Fan Unit
This switch can operate indefinitely with less than a full compliment of fans in the fan module
inoperable so long as the ambient temperature is below 45° Celsius.
Do not attempt to insert a PS unit with a power cord connected to it.
The green PS unit indicator should light. If not, repeat the whole procedure to extract
the PS unit and re-insert it.
Operation without a fan unit should not exceed two minutes.
During fan hot-swap, if the LED indicator is OFF then the fan unit is disconnected.
