Ethernet Ports

The XSR comes equipped with two Ethernet (LAN) 10/100Base-T ports that support full-duplex
10 or 100 Mbps transmission. Both ports conform to IEEE 802.3 standards with 8-pin modular RJ-
45 connectors. A cross-over cable is used to connect the XSR directly to a PC or uplink port while a
straight-through cable is used to attach the router to a hub or switch.
