Patton electronic quick start Grounding the EHA3201, Connecting the Twisted-Pair Line Interface

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.
