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.

APPENDIX B
EIA/TIA TSB-40A COMPLIANCE
The Model 571/81 series surge protectors have been designed to
conform to stringent EIA/TIA TSB-40 standards as required for all
Category-5 connecting hardware. These standards specify the
capacitance and near end cross-talk (N.E.X.T) to insure proper
operation of ALL connected equipment. Specific test results are shown
in the tables on the following pages*.
*Note:
All test results are for the Model 571/581
alone,
not
including the standard 6” (15.25cm) patch cable that is
shipped with the unit.
