1. PRODUCT DESCRIPTION
Introduction
Introduction
The PoLRE switch is a Power over Long Reach Ethernet switch. Unlike traditional Ethernet switches, the
PoLRE switch has a reach of up to 1200 feet (365 meters) and is capable of delivering power and signaling
over a single pair CAT3 cable. A Phylink adapter is installed at each IP endpoint, carrying the power and
signaling to the connected IEEE 802.3af compliant end devices.
The default PoLRE configuration supports IP phones and provides a plug and play solution for replacing a
legacy voice network using the existing network cabling plan. Up to 48 IP phones can be powered from a
single PoLRE switch.
The PoLRE switch is a 1U, 19", rackmount 24/48-port Power over Ethernet (PoE) switch. Its upstream
ports connect to the IP PBX, router or data switch over a GbE copper connection. Unlike the typical PoE
switch, however, its downstream ports connect to either one or two 25-pair RJ21 connectors and run over
voice-grade CAT3 cable extending up to 1200 feet (365 meters).
This permits the use of a legacy 2-wire telephony infrastructure to carry voice, data and signals between
the upstream switch or IP PBX to all IP endpoints in the network. Phylink adapters at the IP endpoints are
like media converters that switch from the single CAT3 pair to a standard RJ45 Ethernet PoE connection
for connectivity and power to the attached IP device.
Important: Devices attached at the IP endpoints must be IEEE 802.3af compliant.
IP telephony (IPT) systems deploying the PoLRE switch provide both the robustness of traditional
telephony systems and the easy mobility of IP devices. Multiple PoLRE switches can also be daisy-chained
together to operate in Powershare mode if one switch’s power supply should fail.

2. UNPACKING
Before You Install
Europe, Middle East, Africa, Asia Pacific
Please have your Channel Support Agreement/Contract Number and password ready when calling.
Before You Install
WARNING: The PoLRE switch can be installed in any indoor location in all countries except in
Finland, Norway and Sweden, where, in these three Nordic countries, it must be installed in a
restricted access location.
The location has to meet the following size, distance and environmental criteria.
Size Requirements
Select a standard 19" equipment rack or, for a standalone PoLRE switch, a flat, stable surface capable of
supporting the size and weight of the PoLRE switch, its installable components and cabling. Refer to PoLRE
Switch Dimensions, page 4.
Ensure that you have enough rack space for all equipment. Shelves and rear supporting brackets are not
mandatory. See Installing the Switch in a Rack, page 21.
Physical Location Requirements
Power
The PoLRE switch must be placed within 6 feet of an available AC power source. Do not use an extension
cord to connect the equipment to a power outlet.
Ventilation
To ensure proper ventilation of the PoLRE switch, leave at least 2 inches of unobstructed space on all
sides of the switch. If the fans are blocked, the unit could overheat. Refer also to Operating/Storage
Environment, page 5.
Downlink
The Phylink adapters can be installed up to 1200' (365m) away from the PoLRE switch.
