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.
