Optional e-POI Subracks
e-POI Modules
The e-POI Modules provide a wide-band, high power, low-PIM, interface and attenuation for the ERA RFD
Cards. Each e-POI Module can handle all frequency bands as well as multiple operators. Each e-POI Module
has four duplexed ports that supply support for up to four interfaces. e-POI modules are hot swappable; you
do not need to power down the e-POI subrack to add or remove them. However, there are steps you should
take to avoid false alarms; please see "Removing an e-POI Module from an e-POI Subrack” on page 80.
The following graphic and table identify the e-POI Module connectors.
