1.2 RADIO AND TV INTERFERENCE (FCC PART 15)
This device generates and uses radio frequency energy, and if not
installed and used properly-that is, in strict accordance with the manufacturer's instructions-may cause interference to radio and television reception. The device has been tested and found to comply with the limits for a
Class A computing device in accordance with specifications in Subpart B

1.6 SAFETY WHEN WORKING WITH ELECTRICITY
• This device contains no user serviceable parts. This
device can only be repaired by qualified service personnel.
• Do not open the device when the power cord is connected. For systems without a power switch and without
an external power adapter, line voltages are present
within the device when the power cord is connected.
• For devices with an external power adapter, the power
adapter shall be a listed Limited Power Source. The
mains outlet that is utilized to power the device shall be
within 10 feet (3 meters) of the device, shall be easily
accessible, and protected by a circuit breaker in compliance with local regulatory requirements.
• For AC powered devices, ensure that the power cable
used meets all applicable standards for the country in
which it is to be installed.
• For AC powered devices which have 3 conductor
power plugs (L1, L2 & GND or Hot, Neutral &
WARNING
Safety/Protective Ground), the wall outlet (or socket)
must have an earth ground.
• For DC powered devices, ensure that the interconnecting cables are rated for proper voltage, current, anticipated temperature, flammability, and mechanical
serviceability.
• WAN, LAN & PSTN ports (connections) may have hazardous voltages present regardless of whether the
device is powered ON or OFF. PSTN relates to interfaces such as telephone lines, FXS, FXO, DSL, xDSL,
T1, E1, ISDN, Voice, etc. These are known as “hazardous network voltages” and to avoid electric shock use
caution when working near these ports. When disconnecting cables for these ports, detach the far end connection first.
• Do not work on the device or connect or disconnect
cables during periods of lightning activity.

WARNING
WARNING
In accordance with the requirements of council directive 2002/96/EC on Waste of Electrical and Electronic
Equipment (WEEE), ensure that at end-of-life you separate this product from other waste and scrap and deliver
to the WEEE collection system in your country for recycling.
This device is NOT intended nor approved for connection to the PSTN. It is intended only for connection to
customer premise equipment.
Electrostatic Discharge (ESD) can damage equipment
and impair electrical circuitry. It occurs when electronic
printed circuit cards are improperly handled and can
result in complete or intermittent failures. Do the following to prevent ESD:
• Always follow ESD prevention procedures when
removing and replacing cards.
• Wear an ESD-preventive wrist strap, ensuring that it
makes good skin contact. Connect the clip to an
unpainted surface of the chassis frame to safely channel unwanted ESD voltages to ground.
• To properly guard against ESD damage and shocks,
the wrist strap and cord must operate effectively. If no
wrist strap is available, ground yourself by touching the
metal part of the chassis.

2.2 DESCRIPTION
The Patton Electronics Model 2172A CopperLink modems provide highspeed LAN connections between peered Ethernet LANs, remote PC’s, or
any other network enabled 10/100Base-T device.
Operating in pairs, one Model 2172A is configured as the (L) Local unit
located at one end of the LAN extension and the other Model 2172A is
configured as the (R) Remote unit at the other end. The Model 2172A is
configured as a L or R via the switch on the bottom of the unit. These units
can automatically forward LAN broadcasts, multicasts, and frames across
a 2-wire voice-grade twisted-pair link. The data is passed transparently
(unmodified) through the 2172As. The 2172As automatically add and
delete MAC addresses, only passing packets across the CopperLINK link
that are meant for the remote peered LAN.

Figure 1.
Typical application
The pair of 2172A models work together to create a transparent extension
between two peered Ethernet LANs. Figure 1 shows a typical point-topoint application.

perature, flammability, and mechanical serviceability.
To install the 2172A Ethernet Extender, do the following:
1. Connect the line interface between the units (refer to section 3.1,
“Connecting the Twisted-Pair Line Interface” on page 10)
Note
See Figure 2 for the standalone unit’s rear panel arrangements.
2. Connect the Ethernet interface (refer to section 3.2, “Connecting the
10/100Base-T Ethernet Interface” on page 11).
3. Connect the power plug (refer to section 3.3, “Connecting Power” on
page 12).

The Model 2172A supports communication between two peer Ethernet
LAN sites over a distance of up to 4,250 ft (1.3 km) over 24 AWG
(0.5 mm) twisted-pair wire.
Model 2172A standalone rear panel
Note
Actual distance and link performance may vary depending on
the environment and type/gauge of wire used.
Follow the steps below to connect the Model 2172A CopperLINK Interfaces.
Note
The Model 2172A units work in pairs. One of the units must be
configured as a (L) Local unit, and the other unit must be configured as a (R) Remote unit. It does not matter which end is the L
and which is the R. The link is always initiated by the R unit. As
long as the L unit is powered on, the R unit can establish a link
by being powered on or by having its power reset.

1. To function properly, the two Model 2172As must be connected
together using twisted-pair, unconditioned, dry, metal wire, between
19 (0.9mm) and 26 AWG (0.4mm). Leased circuits that run through
signal equalization equipment are not acceptable.
2. The Model 2172A is equipped with an RJ-45 interface jack that can
be used on the CopperLINK interface. The CopperLINK interface is a
two-wire interface. Observe the signal/pin relationships on the Model
2172A's CopperLINK interface jack.
The RJ-45 connector on the Model 2172A's twisted pair interface is
polarity insensitive and is wired for a two-wire interface. The signal/pin
relationship is shown in Figure 3.

perature, flammability, and mechanical serviceability.
The Model 2172A does not have a power switch, so it powers up as soon
as it is plugged in.
An external AC or DC power supply is available separately. This connection is made via the barrel jack on the rear panel of the Model 2172A. No
configuration is necessary for the power supply (See Appendix B for
domestic and international power supply and cord options).
DC power (supplied via the power supply jack to the 2172A) must meet
the following requirements; DC power supplied must be regulated
+5VDC ±5%, 1.0A minimum. Center pin is +5V. The barrel type plug has
a 2.5/5.5/10mm I.D./O.D./Shaft Length dimensions.
4.0 CONFIGURATION
The Model 2172A has four DIP switches (S1) for configuring the unit for a
wide variety of applications. This section describes switch locations and
explains the different configurations.
4.1 CONFIGURING THE HARDWARE DIP SWITCHES
Using a small flat-tip screwdriver, remove the protective cover located on
the underside of the Model 2172A (see Figure 5).
