DFE-908DxEOL EOS

Unmanaged Dual-speed Desktop Hub Stack

Description

Dual-speed Flexibility
With Ethernet/Fast Ethernet support at the port level, users can deploy 100Mbps when needed, and still run 10Mbps on some desktops on the network.

Easy Migration
Migration from Ethernet to Fast Ethernet requires no installation of new hubs, no reconnection of hub ports, no change of wiring. As the most cost- effective devices for migration to high-bandwidth, these hubs protect users’ investment by extending their lifespan through transition from 10Mbps to 100Mbps.

Scalable Expansion
Stackable in groups of 5, the hubs allow users to gradually add ports as their network expands. Users can start with a single hub with 8 ports, then add units to eventually reach 40 ports per stack, without incrementing the repeater counts. An MDI uplink interface allows easy cascading of 2 stacks to bring the port density up to 78.

Easy to Use
Each port on the hubs supports dual 10/100Mbps speeds. The hub auto-negotiates the speed with the connected nodes and creates independent 10Mbps and 100Mbps segments. No configuration setting is necessary, and Ethernet and Fast Ethernet users can be physically located anywhere on the network.

10/100Mbps Integration
Model DFE-908Dx is equipped with built-in 10/100Mbps packet switching capability. With a single DFE-908Dx hub, connection between 10Mbps and 100Mbps segments of the entire stack is transparent, allowing Ethernet and Fast Ethernet users to talk to each other on the same network.

Ideal for Small Workgroups
Compact and lightweight, the DFE-908Dx can be placed in tight desktop space and easily relocated when necessary. Small in size, small in budget, this hub is the solution for the smaller workgroups needing flexible expansion, flexible upgrades, and cost-effective networking.
