IDU Installation Requirements for Edge
Table 3-3. IDU for Edge Installation Requirements
Function / Requirement Description
Restricted Access The IDU and its associated dc power supply should be installed
in a restricted access area such as a secure equipment room,
closet, cabinet or the like.
Required Rack Space The IDU requires 44.5 mm (1RU) of vertical rack space and
160 mm rack depth.
Ventilation IDUspe has no cooling fans. Ensure there is a clear 50mm
space either side of the IDU for convection cooling purposes.
Ensure the maximum ambient temperature specifications are
not exceeded.
Maximum Ambient
Temperature
IDUspe 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 an IDU, which if installed
in a rack, is the ambient applying at its location within the
rack.
Physical Stability Ensure that adding an IDU to a rack does not adversely impact
the physical stability of the rack.
Power Supply The IDUspe power connections are isolated from chassis
ground. It can be connected to a ground isolated power
supply, or to a power supply that has either its positive or
negative output connected to ground.
Where an isolated-from-ground power supply system is used,
any switching or disconnection devices fitted in the power
supply cabling must disconnect both +Ve and -Ve feeds.
Where the power supply has one of its outputs connected to
ground, there must be no switching or disconnecting devices
in this ground conductor between the power supply and the
point of connection to the IDU.
Power Supply Location The IDU should 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.
