Intrabuilding interfaces
and cabling for NEBS
compliance
Intrabuilding connections to/from Eclipse ports must only be
connected via intrabuilding or unexposed wiring or cabling.
Intrabuilding ports MUST NOT be metallically connected to
interfaces that connect to the OSP or its wiring. These interfaces are
designed for use as intrabuilding interfaces only (Type 2 or Type 4
ports as described in GR-1089-CORE, Issue 4) and require isolation
from the exposed OSP cabling. The addition of Primary Protectors
is not sufficient protection in order to connect these interfaces
metallically to OSP wiring.
Shielded and grounded cables must be used for intrabuilding
cabling to/from Eclipse ports. Cables must be grounded at both
ends.
Protection from RF
Exposure
When installing, servicing or inspecting an antenna always comply
with the following:
• Locate the antenna such that it does not infringe the RF exposure
guidelines for general public. Refer to
RF Exposure.
• Do not stand in front of or look into an antenna without first
ensuring the associated transmitter or transmitters are switched
off.
• At a multi-antenna site ask the site owner or operator for details
of other radio services active at the site and for their
requirements/recommendations for protection against
potentially harmful exposure to RF radiation.
• When it is not possible to switch transmitters off at a
multi-antenna site and there is potential for exposure to harmful
levels of RF radiation, wear a protective suit.
• Do not look into a waveguide port when the radio is active.
Fiber Optic Cables Handle optical fibers with care. Keep them in a safe and secure
location during installation.
Do not attempt to bend them beyond their minimum bend radius.
Protect/cover unconnected optical fiber connectors with dust caps.
Ground Connections There must be no switching or disconnecting devices fitted in
ground conductors.
Mains Power Supply
Routing
Eclipse dc power, IF, tributary, auxiliary and NMS cables are not to
be routed with any AC mains power lines. They are also to be kept
away from any power lines which cross them.
Maximum Ambient
Temperature
The maximum ambient temperature (Tmra) for an Eclipse indoor
unit is +45° C (113° F). To ensure correct operation and to
maximize long term component reliability, ambient temperatures
must not be exceeded. Operational specification compliance is not
guaranteed for higher ambients.
Mechanical Loading When installing an indoor unit in a rack, ensure the rack is securely
anchored. Ensure that the additional loading of an Eclipse indoor
unit or units will not cause any reduction in the mechanical stability
of the rack.
