Figure 3-5  Nexus RT Cable Connections

1— RF Input/Output – Donor Side. The reverse transmit and forward receive signals are duplexed onto 
one RF port. There is one donor side connector for each band.
2—RF Input/Output – Service Side. The forward transmit and reverse receive signals are also duplexed 
onto one RF port. There is one service side connector for each band.
3—Power Input – Prime power input for the repeater. 
4—IP Connections – Ethernet connections for control and status of the Nexus RT. One for local and one 
for wide area network (WAN). 
5—Serial Port. An RS-232 interface for factory use only. 
6—External Alarm Input. This is a connection port for alarm input signals external to the Nexus repeater.

The Nexus RT also has a wireless modem interface for communicating control and status information with the 

network management system. The repeater supports a USB interface between the Network Element 

Procesor (NEP) and modem.

Local regulations need to be followed for the main power connection. Nexus RTs are approved in accordance 

with EN and UL/cUL regulations. This is, however, only valid if a classified power cord is used. For the 

Nexus RT to meet these regulations you must select one of the following classified and approved cord types:

❑     EN – H 05 W5 - F HMR

❑     UL – AWM Style 2587

❑     CSA– AWM 1 A/B 11 A/B

For outdoor use, the power cord should meet at least IP65 encapsulation requirements. Do not turn the main 

power on until you are ready to commission the Nexus RT

WARNING: For Nexus RTs supplied from the main power source, the main outlet must be 
grounded.

RF cable connections should be verified both internally and externally before powering up the equipment. 

This section describes the general internal connections of the Nexus RT. Verify these connections with the 

as-built drawings and documents for your specific system configuration. 
1. Connect the service and donor antenna coaxial cables to the appropriate terminals on the cabinet.
2. Plug the main power cord into the terminal labeled POWER.
