Chapter 3 Installing and Connecting the Router
Connecting WAN, LAN, and Voice Interfaces
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
Caution To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
connect Gigabit Ethernet ports using RJ-45 connectors for shielded twisted pair cable only to
intra-building or unexposed wiring or cable. The intra-building cable must be shielded and the shield
must be grounded at both ends. The intra-building port(s) of the equipment or subassembly must not be
metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed
for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue
4) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not
sufficient protection in order to connect these interfaces metallically to OSP wiring.
Warning Never install telephone jacks in wet locations unless the jack is specifically designed for wet
locations. Statement 1036
Warning Never touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface. Statement 1037
Warning Class 1 laser product. Statement 1008
