OPTIONAL e-POI SUBRACKS
This section provides a product overview and installation instructions for the optional ERA Series Point of
Interface (e-POI) Subrack (PN 7676311-xx). You use an e-POI Subrack to attenuate high-power RF signals
from their source to the CAN, across all frequencies.
The universal e-POI Subrack provides power, housing, and communications for up to eight e-POI Modules.
The e-POI Subrack ships with the Interface Card (IFC) factory installed. The e-POI Subrack and the Interface
Card and e-POI Module have an operating temperature range of -5 to +50 °C (+23 to +122 °F).
The following graphic and table identify the e-POI Subrack back-panel connectors.
To maximize airflow through the e-POI chassis, blank modules must be installed in all empty slots. If
additional ERA e-POI Blank Modules (PN 7673474-xx) are required, contact your local CommScope sales
representative.
