B-FOCuS O-4F2P Installation
ECI Telecom Ltd. Proprietary 3-3
Site Preparation
Environmental Requirements
The ONT ambient temperature should not exceed 45° C and a relative humidity
ranging from 5% to 95%.
Installation Location
The ONT should be located within 2 meters of the closest electrical point and
within reach of the fiber termination point.
Installation Options (application dependent)
With BBU (Battery Backup Unit) or Ready for BBU
When installed with a BBU or in preparation for a BBU to be added to the
installation, the ONT must be installed on a wall with the connector side face
down such that the cables leave the unit from the lower side. Wall installation
is recommended for all applications.
No BBU
If no BBU is used, the ONT could also be installed flat on a desk or on the
underside of a table. However, for this type of installation, special care must be
taken to ensure that the ONT is fixed in place and that the fiber is protected.
This is not the recommended installation procedure.
Power Requirements
The ONT is shipped with a universal power adaptor. However, before
installation, check if the AC power input matches the specification printed on
the power adaptor (input voltage, current, etc.)
CAUTION: Please use the power adaptor within the package
only, or the replacement unit that provided by ECI. Other
power adaptor may cause damage to the ONT.
