Product Description 

The dual-speed standalone Ethernet/Fast Ethernet hub is designed to 

allow easy migration and integration between 10Mbps Ethernet and 
100Mbps Fast Ethernet, while providing flexibility in cable 

connections. 

The device can operate with both IEEE 802.3 10BASE-T connections 

(twisted-pair Ethernet operating at 10 megabits per second) and 
IEEE 802.3u 100BASE-TX connections (twisted-pair Fast Ethernet 

operating at 100 megabits per second). All of the twisted-pair ports 

support Auto-Negotiation (NWay), allowing the hub to automatically 
detect the speed of a network connection. 

The hub has 8 ports and can have a single uplink connection to 

another 100BASE-TX Class II Fast Ethernet repeater (hub or hub 

stack). 

On the hub, the 10Mbps and 100Mbps segments are separate and do 

not intercommunicate. The device contains a built-in switch, making 

it possible to transparently bridge between the 10Mbps and 100Mbps 

segments. 

Features 

♦ 

Compatible with the IEEE 802.3 10BASE-T Ethernet and 802.3u 

100BASE-TX Fast Ethernet industry standards for 

interoperability with other Ethernet/Fast Ethernet network 

devices 

♦ 

Eight NWay RJ-45 ports for connecting stations to the network 

♦ 

Built-in switching function supports bridging between 10Mbps 

and 100Mbps segments 

 

♦ 

LED indicators for power, collision, link,  network activity,  and 
operating speed (10 or 100 Mbps) 

♦ 

Auto-partitioning for network protection
