Ethernet Ports; Copper/Fiber-Optic Ethernet Nims - Enterasys X-Pedition XSR-1805 Getting Started Manual

Ethernet Ports

The XSR comes equipped with two Ethernet (LAN) 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. Refer to

Copper/Fiber-optic Ethernet NIMs

The single-port Copper or Fiber-optic Ethernet NIMs, shown in
provide interfaces for half and full-duplex 10/100Base-T or fiber-optic 100Base-F transmission
over LAN or WAN networks, respectively. The Copper Ethernet NIM incorporates a standard 8-
pin modular RJ-45 connector and the Fiber-optic Ethernet NIM has an MT-RJ multi-mode
interface. Both NIMs conform to IEEE 802.3 and PCI 2.2 standards.
