Fast Ethernet Connectivity

Fast Ethernet and 10BaseT Ethernet Network Modules Including: NM-1FE-TX, NM-1FE-FX, NM-4E, NM-1E
Ideal for a wide range of LAN applications, the Fast Ethernet network modules support many internetworking
features and standards. Single port network modules offer autosensing 10/100BaseTX or 100BaseFX Ethernet.
The TX version supports virtual LAN (VLAN) deployment.
In customer networks, these modules may be useful for the following:
• Uplink to Fast Ethernet backbones on Catalyst
®
series switches and other Cisco routers.
• VLAN support on the NM-1FE-TX module, allows network managers to group users logically rather than
by physical location, easing adds, moves, and changes within the network. The Cisco Inter-Switch Link (ISL)
protocol enables VLAN traffic communication with Catalyst 6500, 5000, 5500, and Catalyst 3000 series
switches.
• Provides inter-VLAN routing services between VLANs on any Catalyst series switch that supports VLANs.
The module will offer future support the new 802.1Q VLAN standard.
– Cabling—RJ-45 connector for 1FE-TX, fiber connector for 1FE-FX
– LEDs—Network module status indicator, status LEDs for link status, LAN speed, and half/full duplex
– Network interfaces—One 10/100 base-TX or FX port
