Hazardous network voltages are present in the BRI cables. If you detach the
cable, detach the end away from the SmartNode or interface card first to avoid
possible electric shock. Network hazardous voltages may be present on the
device in the area of the BRI port, regardless of when power is turned OFF.
To prevent damage to the system, make certain you connect the
BRI cable to the BRI port only and not to any other RJ-45 socket.
