Chapter 3 Installing the Cisco VG224 Voice Gateway
Connecting Cables
Connecting Cables
For cables not included with your Cisco VG224 voice gateway, pinout information is in Appendix A,
“Cable Specifications and Information.” Cisco VG224 voice gateway ports are color-coded for
identification.
Warning
Do not work on the system or connect or disconnect cables during periods of lightning activity.
Statement 1001
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 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.
