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 router is OFF or ON. To
avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away
from the router first. Statement 1026
Warning
This unit is intended for installation in restricted access areas. A restricted access area can be accessed only
through the use of a special tool, lock and key, or other means of security. Statement 1017
Warning
Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the
Caution
built in Gigabit Ethernet ports only to intra-building or unexposed wiring or cable. The intrabuilding 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.
To comply with Telcordia NEBS GR-1089-Core and EN 300386 requirements, you must use foil twisted-pair cable
Caution
that is properly grounded at both ends.
Power Connections
This section describes procedures for connecting your router to AC power, DC power, and backup power. See the appropriate
subsection:
• Connecting the Routers to AC Power, page 16
• Connecting the Router to DC Power, page 17
• Connecting the Router to Backup Power, page 22
Warning
Read the installation instructions before connecting the system to the power source. Statement 1004
The installation must comply with all required electrical codes applicable at the installation site.
Note
Connecting the Routers to AC Power
If your router uses AC power, connect it to a 15 A, 120 VAC (240 VAC, 10 A) circuit with overcurrent protection. If backup
power is required, see the "Connecting the Router to Backup Power" section on page 22.
Note
The input voltage tolerance limits for AC power are 85 and 264 VAC.
