EXT-100-Main Extender Applications

EXT-100-Main Quick Install Guide

The EXT-100-Main Extender Solution is designed to supercharge the downlink ports of a 
standard Ethernet switch delivering 10/100 Mbps symmetrical (full duplex) and PoE over 

four-pair UTP infrastructure with distances up to 2,000 ft (610 m).  The EXT-100 offering is 
designed  specifically  to  enable  easy  deployment  over  UTP  for  reaches  beyond  that  of 

standard Ethernet eliminating the costs and disruption associated with IDF closet 
requirements.

To Switch

1. Remove the EXT-100-Main from its packaging.
2. Must ensure cable is properly terminated before connecting any EXT-100 product.
3. Remove all legacy equipment from the UTP cable infrastructure.

NOTE: 

In order to avoid damage to devices, it is important that only IP devices are connected when you 

connect the EXT-100-Main.

4. Connect EXT-100-Main (Switch side) to downlink port on switch.
5. Connect the Network Infrastructure cable from the EXT-100-Main (Remote side) to EXT-100-Remote (Main 

side)

6. Using Cat 5e or higher category cable, connect the device to the EXT-100-Remote (Device side). 

NOTE: 

Berk-Tek recommends using LANmark IP (22AWG) or higher for indoor applications; LANmark-6 OSP, 

LANmark-1000 OSP, or LANmark-10G OSP should be used for outdoor applications.

The EXT-100-Remote must be installed either indoors or in a NEMA rated box appropriate for the installation 

environment.
Installations must be compliant with the requirements of the local authority having jurisdiction.
