Connecting Cables
Warning
Do not work on the system, or connect or disconnect cables during periods of lightning activity. Statement 1001
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
Read the installation instructions before connecting the system to the power source. Statement 1004
Warning
This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that the
protective device is rated not greater than:
120 VAC, 15A (240 VAC, 10A international) Statement 1005
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
To prevent accidental discharge in the event of a power line cross, route on-premise wiring away from power
cables and off-premise wiring, or use a grounded shield to separate the on-premise wiring from the power cables
and off-premise wiring. A power line cross is an event, such as a lightning strike, that causes a power surge.
Off-premise wiring is designed to withstand power line crosses. On-premise wiring is protected from power line
crosses by a device that provides overcurrent and overvoltage protection. Nevertheless, if the on-premise wiring
is in close proximity to, or not shielded from, the off-premise wiring or power cables during a lightning strike or
power surge, the on-premise wiring can carry a dangerous discharge to the attached interface, equipment, and
nearby personnel. Statement 338
Warning
Before performing any of the following procedures, ensure that power is removed from the DC circuit. Statement
1003
Warning
This equipment has been designed for connection to TN and IT power systems. Statement 1007

one type of power. Do not use AC and DC power at the same time. If you do, the unit stops operating, and you
must reboot it with only a single power source.
These cables and connections are described in Table 2 and Figure 12.
