Cooling for One or Two Enclosures
When one or two enclosures are mounted in a rack or cabinet, one
directly above the other, with no other equipment directly below, natural
convection provides sufficient airflow through the enclosures.
When one or two enclosures are rack-mounted with other equipment
directly below that produces rising heat, a 9 cm space is required
between the enclosure and the other equipment to exhaust hot air from
below. A
deflector must be fitted into this space to avoid mixing the air
flows (Figure 1-5).

Cooling for Three or More Enclosures
When three or more enclosures are mounted in a rack or cabinet,
forced-air cooling with fans and a deflector is required.
