3.1 PRODUCT APPLICATIONS
Both Models 571 and 581 protect 4 pins on the modular RJ-45 Cat-
5 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.

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
