Controlling the Operating Temperature
32 to 122°F (0 to 50°C). Avoid damage to this product! Your warranty
is void if you operate this product above or below the maximum
speciﬁ ed operating temperatures.
Measuring the Inlet Air Temperature
If you are concerned about inlet air temperature at the air inlet of any
demodulator, you can measure the inlet air temperature in the rack. When
measuring the temperature, ensure that all cabling is complete and that
all adjacent QPSK demodulators are installed and running.
Important: Opening the door on the back panel of the rack may have an
adverse effect on the managed airﬂ ow. If access to the door is not controlled,
measure the inlet air temperature with the back panel door open because
this typically redirects the airﬂ ow in an adverse manner.
