Cooling System
The Trinix uses fan modules (FM-33000) for cooling the main chamber of
the chassis. A fan module consists of two blower-type fans that are
housed in a mechanical assembly. The 128 x 128 chassis uses two mod-
ules, the 256 x 256 chassis uses three, and the 512 uses six. The fan
modules are front-loading and hot-swappable.
Airflow openings for the 128 chassis are shown in Figure 8. Air is taken
in from the sides of the chassis (primarily the left side), where the air is
drawn across the I/O cards, past the matrix card, and up to the top rear
of the chassis where it is expelled. A small amount of air is drawn from
the right side of the chassis as well to help cool the matrix board.
