Connecting to the T1/E1/PRI WAN ports

An active T1/E1/PRI is not necessary to configure the RAS. However, an active T1/E1/PRI connection is required to receive or make calls. The factory-set default configuration of the access server has the T1/E1 ports disabled.

Note The cable connecting the T1/E1/PRI WAN ports to the RJ-48C ter- mination jack should be CAT-3 or higher and extend no farther than 1 mile from the digital services termination.

1.Refer to figure 11 for the T1/E1/PRI RJ-48C pinout diagram.

2.Attach the network cable from the telephone network demarc to the Primary T1/E1/PRI port (RJ-48C) on the RAS.

Note For 75-ohm twin-coax E1 connections, use the Black Box Model MT 242A E1 120-ohm/75-ohm adapter to convert from a 75-ohm dual-coax to the 120-ohm twisted-pair interface the RAS uses.

Completing the hardware installation

This section verifies that the RAS hardware is operational to the point where you can begin configuring the software settings.

The RAS power supply automatically adjusts to accept an input voltage of from 90 to 260 VAC (50 to 60 Hz).

Verify that the proper voltage is present before plug- ging the power cord into the receptacle. Failure to do so could result in equipment damage.

1.Verify that the AC power cord included with your RAS is compatible with local standards.

2.Connect the male end of the power cord to an appropriate power outlet.

3.Verify that the green POWER LED is lit. If the POWER LED is flashing green, refer to Chapter 5, “Trou- bleshooting and maintenance”.

Hardware installation is complete. Refer to Chapter 3, “Configuring the RAS for operation”.
