Kalypso HD Frame
HD Video Processor Frame
The Kalypso HD Video Processor frame is a 13 rack unit chassis which
mounts in a standard 483 mm (19 in.) rack (
Figure 68 on page 72 ). An addi-
tional 2 rack unit power supply is also required ( Figure 56 on page 51 ).
The Video Processor frame has a built-in cooling system consisting of a
fan/plenum mounted in the upper section of the frame, and an air filter in
the lower section. Cooling air is drawn in at the lower sides of the frame,
up through the filter and modules, then expelled out the back of the fan/
plenum. In racks with forced air cooling that enters from above, heated
exhaust air may be forced down to the air intakes and cause elevated frame
temperatures. In these cases installing ducts or baffles to keep airflows sep-
arate is advised.
