Details
The INU/INUe and its associated dc power supply must be installed in a
restricted access area such as a secure equipment room, closet, or cabinet.
The INU requires 44.5 mm (1RU) of vertical rack space and 300 mm rack
depth. The INUe requires 89mm (2RU) vertical rack space.
The INU/INUe requires unobstructed air passage to each side for ventilation
purposes. There must be a minimum of 50 mm (2 in.) of side spacing to any
rack panels, cable bundles or similar. No space above or below is required for
ventilation purposes.
The INU/INUe is specified for a maximum ambient temperature (Tmra) of
+45° Celsius (113° Fahrenheit). The maximum ambient temperature (Tmra)
of +45° Celsius applies to the immediate operating environment of the INU,
which if installed in a rack, is the ambient applying to its location within the
rack.
Ensure that adding an INU/INUe to a rack does not adversely impact the
physical stability of the rack.
The INU has the +ve pin on its dc power supply connector fastened directly to
the chassis.
It must be used with a -48 Vdc power supply which has a +ve ground; the
power supply ground conductor is the +ve supply to the INU.
There must be no switching or disconnecting devices in the ground conductor
between the dc power supply and the point of connection to an INU/INUe.
The INU/INUe must be installed in the same premises as its dc power supply
and be located in the same immediate area (such as adjacent racks or cabinets)
as any other equipment that is connected to the same dc power supply.
