• If mounting the switch in an open rack (no side panels):
–
The horizontal distance between the chassis and any adjacent chassis
should be 6 inches (15.2 cm), and the distance between the chassis air
vents and any walls should be 2.5 inches (6.4 cm).
–
The distance between the outside face of the front mounting rail and the
outside face of the back mounting rail should be 24 - 34 inches (61.0 -
86.4 cm) to allow for rear bracket installation, with a recommended
distance of 25 inches (63.5 cm).
• If mounting the switch in an enclosed cabinet that has perforated front and
back doors:
–
The distance between the side edge of the chassis and the side of the
cabinet should be at least 2.5 inches (6.4 cm). No sizeable flow
obstructions should be in the way of the chassis side air intake or exhaust
vents.
–
The cabinet depth should be 36 - 42 inches (91.4 - 106.7 cm) to allow
adequate airflow. If cable management brackets are used, the front
mounting rails of the cabinet should be offset from the front door by
6 inches (15.2 cm) minimum.
–
The distance between the outside face of the front mounting rail and the
outside face of the back mounting rail should be 24 - 34 inches (61.0 -
86.4 cm) to allow for rear bracket installation, with a recommended
distance of 25 inches (63.5 cm).
–
Front and rear doors must be entirely perforated with at least 65% open
area.
–
The floor of the cabinet must be either open or perforated.
–
A roof-mounted fan delivering 500 CFM is recommended but not
required.
–
A minimum of 5 inches (12.7 cm) should be maintained between the roof
and the top of the highest piece of rack mounted equipment for airflow.
