In the event that scratches are incurred during equipment installation, note that
touch up paint is available in a spray can via part number 6010-1522C.
Cooling
Instrument racking influences airflow in two significant ways: the proximity to
the rear of the rack, and placement of the highest heat-producing pieces of
equipment. Equipment protruding the closest to the back should be placed
lower, to prevent them from trapping heat and creating eddy currents as shown
in Figure 9.
Figure 9
Good and Bad Examples of Equipment Racking Vs Cooling
Components generating the most heat should be placed closest to the top to
avoid heating the equipment above it as the generated heat rises in the
convection current. Figure 10 shows projected temperature with and without the
extractor fan.
