4 EHA3201 Quick Start Guide
1.1 Grounding the EHA3201
Before installing the EnviroNET G.SHDSL Router, it is important to establish a good grounding connection first.
1. Assemble a ground wire using #10 AWG wire with green-and-yellow-colored insulation and two ring ter-
minals. Make the wire long enough to reach one of the following earth ground sources:
•
The building ground rod (generally located at the site’s main service entrance)
•
A sprinkler system pipe
•
A cold-water pipe
•
Building structural steel
2. Install the grounding wire between the grounding stud (see Figure 1 on page 3) and the grounding
source.
1.2 Connecting the Twisted-Pair Line Interface
To function properly, the G.SHDSL Router must be connected 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.
The G.SHDSL Router is equipped with an RJ-45 interface jack (Line), which is a two-wire interface. Observe the
signal/pin relationships on the G.SHDSL Router’s Line interface jack. The signal/pin relationship is shown in
figure 2.

1.3 Connecting the 10/100Base-T Ethernet Interface
The G.SHDSL Router has an unshielded RJ-45 auto-MDIX10/100Base-T interface. This port is designed to con-
nect directly to a 10/100Base-T network. figure 3 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.
