1.2 RADIO AND TV INTERFERENCE (FCC PART 15)  
This equipment generates and uses radio frequency energy, and if not  
installed and used properly—that is, in strict accordance with the manu-  
facturer's instructions—may cause interference to radio and television  
reception. This equipment has been tested and found to comply with the  
limits for a Class A computing device in accordance with the specifica-  
tions in Subpart B of Part 15 of FCC rules, which are designed to provide  
reasonable protection from such interference in a commercial installa-  
tion. However, there is no guarantee that interference will not occur in a  
particular installation. If the equipment causes interference to radio or  
television reception, which can be determined by disconnecting the  
cables, try to correct the interference by one or more of the following  
measures: moving the computing equipment away from the receiver, re-  
orienting the receiving antenna, and/or plugging the receiving equipment  
into a different AC outlet (such that the computing equipment and  
receiver are on different branches).  
1.3 CE DECLARATION OF CONFORMITY  
We certify that the apparatus described above conforms to the require-  
ments of Council Directive 2004/108/EC on the approximation of the  
laws of the member states relating to electromagnetic compatibility; and

1.5 SAFETY WHEN WORKING WITH ELECTRICITY  
• This device contains no user serviceable parts. The  
equipment shall be returned to Patton Electronics for  
repairs, or repaired by qualified service personnel.  
• Mains Voltage: Ensure that the external power adapter  
is a listed Limited Power Source. The mains outlet that  
is utilized to power the devise shall be within 10 feet (3  
meters) of the device, shall be easily accessible, and  
protected by a circuit breaker. Ensure that the power  
cable used meets all applicable standards for the coun-  
try in which it is to be installed, and that it is connected  
to a wall outlet which has earth ground.  
WARNING  
• Hazardous network voltages are present in WAN ports  
regardless of whether power to the unit is ON or OFF. To  
avoid electric shock, use caution when near WAN ports.  
When detaching the cables, detach the end away from  
the device first.  
• Do not work on the system or connect or disconnect  
cables during periods of lightning activity.  
In accordance with the requirements of council direc-  
tive 2002/96/EC on Waste of Electrical and Electronic  
Equipment (WEEE), ensure that at end-of-life you sepa-  
rate this product from other waste and scrap and deliver  
to the WEEE collection system in your country for recy-  
cling.  
This device is NOT intended nor approved for connec-  
tion to the PSTN. It is intended only for connection to  
customer premise equipment.  
WARNING  
WARNING  
When the 2172R is mounted, it shall be secured in such  
a way as to withstand a vertical shear force of 50N or 14  
pounds.

2.2 DESCRIPTION  
The Patton Electronics Model 2172R Ruggedized Ethernet Extender  
provides high-speed LAN connections between peered Ethernet LANs,  
remote PC’s, or any other network enabled 10/100Base-T device.  
Operating in pairs, one Model 2172R or 2172 is configured as the (L)  
Local unit located at one end of the LAN extension and the other Model  
2172R or 2172 is configured as the (R) Remote unit at the other end. The  
Model 2172R is configured as a L or R via the switch on the rear panel.

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 2172Rs or 2172s. The 2172Rs  
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 2172R and 2172 models work together to create a transparent  
extension between two peered Ethernet LANs. Figure 1 shows a typical  
point-to-point application.  
3.0 INSTALLATION  
The Interconnecting cables shall be acceptable for  
tion with respect to voltage, current, anticipated tem-  
CAUTION  
perature, flammability, and mechanical serviceability.  
To install the 2172R 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 9)  
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 11).

The Interconnecting cables shall be acceptable for  
external use and shall be rated for the proper applica-  
tion with respect to voltage, current, anticipated tem-  
CAUTION  
perature, flammability, and mechanical serviceability.  
The Model 2172R supports communication between two peer Ethernet  
LAN sites over a distance of up to 6,000 ft (1.8 km) over 24 AWG  
(0.5 mm) twisted-pair wire.  
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 2172R CopperLINK Inter-  
faces.  
Note The Model 2172R units work in pairs. One of the units must be  
configured as a (L) Local unit, and the other unit must be config-  
ured 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 2172Rs 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 2172R is equipped with either an RJ-45 or a terminal block  
interface jack that can be used on the CopperLINK interface. These  
CopperLINK interfaces are a two-wire interface. Observe the signal/  
pin relationships on the Model 2172R's CopperLINK interface jacks.  
The RJ-45 connector on the Model 2172R'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 shielded RJ-45 port labeled Ethernet is the Auto-MDIX10/100Base-  
T interface. This port is designed to connect directly to a 10/100Base-T  
network. Figure 5 shows the signal/pin relationships on this interface.  
You may connect this port to a hub or PC using a straight through or  
crossover cable that is up to 328 ft long.

3.3 CONNECTING POWER  
The Interconnecting cables shall be acceptable for  
external use and shall be rated for the proper applica-  
tion with respect to voltage, current, anticipated tem-  
perature, flammability, and mechanical serviceability.  
CAUTION  
The Model 2172R 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 connec-  
tion is made via the barrel jack on the rear panel of the Model 2172R. 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 2172R) must meet the follow-  
ing 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 2172R has eight DIP switches for configuring the unit for a  
wide variety of applications. This section describes switch locations and  
explains the different configurations.

Switch S2-7: Ethernet Shutdown  
Use switch S2-7 to enable or disable Ethernet Shutdown.When Ethernet  
Shutdown is enabled, the 2172R will disable the Ethernet interface when  
there is no CopperLINK link detected. When Ethernet Shutdown is dis-  
abled, the Ethernet interface will always be enabled.

Note The S2-8 switch applies to the R unit only. If enabled, the R will  
follow the dip switch configuration of the L unit. If disabled, the R  
unit will use its own dip switch setting to determine its Ethernet  
operating mode and Ethernet Shutdown mode configuration.  
The S2-8 switch does not affect the data rate. The data rate will  
always follow the L configuration.  
5.0 OPERATION  
Once the Model 2172Rs are properly installed, they should operate  
transparently. No user settings required. This section describes reading  
the LED status monitors.  
5.1 POWER UP  
Before applying power to the Model 2172R, please review section 3.3,  
“Connecting Power” on page 11 to verify that the unit is connected to the  
appropriate power source.
