5-port Unmanaged Stand-alone Dual Speed Hub
Where to buy


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

Easy to Use
Each port on the hub 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.

Easy Migration
Migration from Ethernet to Fast Ethernet requires no installation of new hubs, no re-connection of hub ports, no change of wiring. As the most cost-effective device for migration to high-bandwidth, the hub protect users' investment by extending their lifespan through transition from 10Mbps to 100Mbps.
10/100Mbps Integration
The hub is equipped with built-in 10/100Mbps packet switching capability. With this, 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.

Scalable Expansion
Stackable in groups of 5, the hub allows 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 count. An MDI uplink interface allows easy cascading of 2 stacks to bring the port density up to 78.

Ideal for Small Workgroups
Compact and lightweight, the hub can be placed in tight desktop space and easily relocated when necessary. Small in size and small in budget, these hubs are the solution for the smaller workgroups that need flexible expansion, flexible upgrades, and cost-effective networking.

1 100Mbps Switch Port
Alternatively 1 of the 4 hub ports can be configured as a switch port running at 100Mbps. This configuration provides a 100Mbps dedicated bandwidth server connection for bottleneck-free access by the 100Mbps
