Rack Mounting Using Rack Rails

The rack mounting kit is used to mount the VNR 100 in a Telco rack or a standard
19 inch (48.3 cm) wide rack with four vertical posts, one in each corner.
ATTENTION:
Elevated operating ambient temperature — If the unit is installed in a closed or
multi-unit rack assembly, the operating ambient temperature of the rack environment
may be greater than room ambient temperature. Therefore, install the equipment in
an environment compatible with the maximum ambient temperature (TMA: +122 °F,
+50 °C) specified by Extron.
Reduced air flow — Install the equipment in the rack so that the equipment gets
adequate air flow for safe operation.
Mechanical loading — Mount the equipment in the rack so that uneven mechanical
loading does not create a hazardous condition.
Circuit overloading — Connect the equipment to the supply circuit and consider the
effect that circuit overloading might have on overcurrent protection and supply wiring.
Consider the equipment nameplate ratings when addressing this concern.
Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted
equipment. Pay particular attention to supply connections other than direct connections
to the branch circuit (such as the use of power strips).
• When multiple units are mounted in the rack, load the rack from the bottom to the
top, with the heaviest unit at the bottom. If this is the only unit mounted in the rack,
it should be mounted at the bottom.
• Lorsque plusieurs unités sont montées dans le rack, chargez le rack du bas vers le
haut, en commençant par l'unité la plus lourde. Si c'est la seule unité montée dans
le rack, elle devrait être montée en bas.
• With the rack rails collapsed, this unit requires a minimum rack depth of 25.5 inches
(64.8 cm).
• Lorsque les rails de rack sont pliées, cette unité nécessite une profondeur de rack
minimum de 64,8 cm (25,5 inches).
• The total room required with the rack rails fully expanded, is 33.5 inches (85.1 cm).
• L'espace total requis avec les rails de rack entièrement étendues est 85,1 cm
(33,5 inches).
