This section describes the conditions that necessitate the use of a heat buffer bracket on
the cage. The Coral IPx cage is designed such that cool air flows into the cage from the
ventilation grille at the bottom of the cage door. See
Figure 6-31
. The free space at the
bottom section of the cage allows cool air to flow into the cage via the ventilation grille
on the door, and then upwards past the cards and power supply. The cool air absorbs
the heat from the circuitry and flows out of the cage via the holes on the top panel.
The top panel must remain clear of objects, as they will interfere with the heat removal
from the cage and could result in a fire.
The bottom panel of the cage is angled such that it forms a gap between the bottom
panel and the top panel of the cage underneath. This gap allows the warm air to be
released. See
Figure 6-33
through
Figure 6-35
. For this reason, whenever a Coral IPx
cage is installed directly above another Coral IPx cage, there is no need to install a heat
buffer bracket. Whenever a Coral IPx cage is NOT installed directly above, a heat
buffer bracket must be installed.
The heat buffer bracket is positioned such that it is impossible to install equipment
directly above the Coral IPx cage. See
Figure 6-32
. This ensures that a minimum space
of 1U (1.75" or 45 mm) is maintained between the top panel of the Coral IPx cage and
any equipment that may be installed above.
