Unmanaged Dual-speed Desktop Hub Stack

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

Easy to Use
All ports support 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.

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, then add units to eventually reach 80 ports per stack, without incrementing the repeater counts. An MDI interface allows easy cascading of 2 stacks to bring the port density up to 158.

10/100Mbps Integration
With the built-in 10/100Mbps switch function, connection between 10Mbps and 100Mbps segments of the entire stack is transparent. This allows users to mix Ethernet and Fast Ethernet stations on the same network completely without any need to configure.

Cost-effective Dual-speed Networking
This hub stack provides the most cost-effective 10/100Mbps hub connection to mixed bandwidth users. Hub-to-hub stacking is done through a daisy-chain cable with DB-25 connectors. 10/100Mbps integration of the entire stack is provided through a single DFE-916Dx with built-in switch function.
