These dimensions are for the product without rack-mount flange adapters; the
overall width of the flanges varies according to the equipment mounting
requirements.
The depth given does not include any I/O or power connectors. The power
connectors add 50 mm (2 inches) to the depth.

Airflow

The Netra ft 1800 system has been designed to function while mounted in a natural
convection airflow, but to meet the declared environmental specification the
following rules apply. Refer to
To allow adequate airflow, the rack should provide either:
Unobstructed vertical airflow via vents of adequate size in the top and/or bottom
panels; in which case the vertical clearance required is 35RU (1556 mm / 61.25
inches). The chassis should be mounted centrally, providing a 1RU plenum
adjacent to each vent grille.
or
A minimum of 37RU (1645 mm / 74.75 inches) of rackable height, with the
provision of 2RU vertical space (89 mm / 3.5 inches) for front and/or rear vents
at both top and bottom.
1. Adequate airflow through the equipment frame must be ensured. The
Netra ft 1800 system utilizes internal fans that can achieve a maximum airflow of
840 cfm in free air. As a fully configured system can release up to 3000W (10,000
BTU/hour), appropriate means to extract heat from an enclosed cabinet should be
provided, for instance, fans mounted in the top of the cabinet.
