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 use RJ-45 connectors. Use caution
when connecting cables.
Caution Inline power circuits provide current through the communication cable. Use the Cisco
provided cable or a minimum 24 AWG communication cable.
