Chapter 5: Site Preparation – Environmental Requirements: Air Temperature Requirements
NOTE
The air temperature inside the system is not
considered stable until the system has been
powered for at least 30 minutes.
If the sensor finds that the air temperature inside the
system is too high, the system will shut down; typically,
the over-temperature shutdown point is 55 C (131 F).
See
on page 5-4 for information
on air conditioning requirements. See
page 5-3 for more temperature and humidity
specifications.
Cooling Requirements
Design the site cooling capability using the heat
dissipation estimates in
. The numbers are for
testheads with fully loaded modules, Serial Test power
supplies, and fully loaded support bays.
