2.1 FEATURES

• Multi-level surge protection

• Operation at Speeds up to 100 Mbps

• Four-wire protection on lines 1, 2, 3, and 6 on Cat-5 RJ-45

• EIA/TIA TSB-40A Category 5 Compliant

• N.E.X.T. better than -43 dB at 100 MHz

• Shunts surges directly to chassis ground

• Easy to install

• Made in the U.S.A.

2.2 DESCRIPTION

Devices that connect to Category-5 cabling systems are routinely
threatened by unwanted electrical energy (lightning, AC power
induction, ESD and more). Higher speed devices–such as those
operating at 100 Mbps–are especially vulnerable to the effects of these
hazards, which can include data loss and hardware damage.

The Patton Model 571 and 581 Series Surge Protectors provide
effective surge protection for devices operating in Category-5 Cabling
Systems. The Model 571 is specifically designed for point-of-use
installation; the Model 581 is designed to be installed at the building
entrance. Both models use a multi-stage Silicon Avalanche Diode
circuit, and will continue functioning while handling the appropriate IEC

801.5 surges applicable to their use (see the tables in Appendix B).
Both the 571 and 581 will additionally protect against surges up to and
exceeding 2kV/1kA in fail-safe mode.

Models 571 and 581 support a wide range of balanced interfaces
running over 4 wires. Highlights include a low insertion loss (less than

0.4dB at 100MHz) and minimal near end cross talk (greater than -43
dB at all frequencies up to 100 MHz). Grounding is accomplished via an
external ground strap that provides a separate unit-ground to chassis­ground connection.

Warning: This product will not provide complete protection
should your equipment or building be subject to a direct
lightning hit.

3.0 INSTALLATION

Patton's Model 571 and 581 surge protectors are easy to install
and are designed to operate transparently to your network. This
section describes connection procedures for both models.

3.1 PRODUCT APPLICATIONS

Both Models 571 and 581 protect 4 pins on the modular RJ-45 Cat­5 interface, and work in environments with data rates up to 100 Mbps.
The following descriptions will give you a general guideline for installing
the units in your Cat-5 environment.

3.1.1 POINT-OF-USE APPLICATION (MODEL 571)

The Model 571 is designed for installation on LAN equipment in a
typical office environment (see Figure 1, below). For best results the
Model 571 should be connected as close as possible to the
communication port of the device to be protected . Also, the flat
braided grounding wire on the Model 571 should be attached to the
grounded metal frame of the device being protected.

Figure 1. A typical Point-of-Use Application for the Patton Model 571.

3.1.2 BARRIER APPLICATION (MODEL 581)

The Model 581 is a more robust protector than the Model 571, and
is designed for use as a barrier protector on LAN equipment in campus
networks. Applications include cable runs between buildings, cable
runs between floors on multi-story structures, and as a higher capacity
replacement for the Model 571.

The Model 581 is also well suited for use in severe lightning areas,
heavy industrial environments, and installations with heavy machinery
in the direct vicinity of sensitive LAN equipment and cabling. Figure 2
(above) shows a typical application for the Model 581. For best results,
the braided grounding strap on the Model 581 should be attached to the
grounded metal frame of the device being protected. When installation
is made at a barrier, such as an external wall, the braided strap should
be connected to a nearby electrical ground.

3.2 INSTALLATION PROCEDURES

In order to operate as designed, the Model 571 and 581 must be

connected correctly

to your Cat-5 network. Please read all the

instructions below and follow them carefully.

Connection of the Model 571 or 581 to an I/O Port

1. Turn off equipment power and unplug (disconnect) the existing
connection between the UTP cable and the equipment’s I/O port.
