Ethernet Connectors
Your Cisco 1113 system has two integrated 10/100/1000-megabit-per-second (Mbps) Ethernet
connectors. ACS SE supports the operation of either Ethernet connector, but not both connectors. Each
Ethernet connector provides all the functions of a network expansion card and supports the 10BASE-T,
100BASE-TX, and 1000BASE-TX Ethernet standards.
Each NIC is configured to automatically detect the speed and duplex mode of the network.

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.
