ECLIPSE INSTALLATION MANUAL
Installation Requirements
This table lists typical INU Installation requirements.
Function/Requirement Details
Restricted access 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.
For NEBS compliance, this equates to installation of the INU/INUe
in a secure, restricted access central office (CO) or customer premises
(CP) location.
Required Rack Space The INU requires 44.5mm (1RU) of vertical rack space and 300mm
rack depth. The INUe requires 89mm (2RU) vertical rack space.
Ventilation The INU/INUe requires unobstructed air passage to each side for
ventilation purposes. There must be a minimum of 50mm (2”) of
side spacing to any rack panels, cable bundles or similar. No space
above or below is required for ventilation purposes.
Fan Air Filter The fan air filter must be installed where the INU/INUe is required to
be NEBS compliant. The filter must be inspected regularly and
replaced when dust laden. Inspection must be at not more than 12
monthly intervals in controlled air environments, or more frequently
otherwise.
Power Line Filter The power line filter must be installed where the INU/INUe is required
to be NEBS compliant.
Maximum Ambient
Temperature
The INU/INUe is specified for a maximum ambient temperature
(Tmra) of +55°Celsius (131° Fahrenheit). Conditions apply - see
Power Supply on page 61. The maximum ambient temperature
(Tmra) 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.
Physical stability Ensure that adding an INU/INUe to a rack does not adversely impact
the physical stability of the rack.
Power supply -48 Vdc The INU (NCC and NPC) has the +ve pin on its dc power supply
connector connected to the chassis.
It must be used with a -48Vdc 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.
For NEBS compliance the battery return connection is to be treated
as a common DC return (DC-C), as defined in GR-1089-CORE.
