Double-Wide High Density Analog Service Module Overview

Installing SM-D-72FXS

Install the SM-D-72FXS according to the instructions in the Installing Cisco Interface Cards in Cisco Access Routers document.

Grounding

Ensure that the equipment you are working with is properly grounded according to the instructions in the Installing Cisco Interface Cards in Cisco Access Routers document.

Cables

The VG350 Voice Gateway uses RJ-21 cables to connect to a distribution box.

Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. Statement 1021

Warning Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the unit first. Statement 1026

Warning This equipment contains a ring signal generator (ringer), which is a source of hazardous voltage. Do not touch the RJ-11 (phone) port wires (conductors), the conductors of a cable connected to the RJ-11 port, or the associated circuit-board when the ringer is active. The ringer is activated by an incoming call. Statement 1042

Warning For connections outside the building where the equipment is installed, the following ports must be connected through an approved network termination unit with integral circuit protection: FXS. Statement 1044

Connecting SM-D-72FXS
