This hub can operate with either IEEE 802.3 10BASE-T connections (twisted-pair Ethernet operating at 10 megabits per second), or IEEE 802.3u 100BASE-TX connections (twisted-pair Fast Ethernet operating at 100 megabits per second). All of the twisted-pair ports support NWay auto-negotiation, allowing the hub to automatically detect the speed of a network connection. This means you can connect all of your Ethernet and Fast Ethernet hosts to any hub in the series, without any rewiring required when a host is upgraded from 10Mbps to 100Mbps.

A stack of four 32-port hubs gives a total of 128 Ethernet or Fast Ethernet ports. A 32-port dual-speed stackable Ethernet/ Fast Ethernet Hubs stack operates as a Class II Fast Ethernet repeater, allowing it to be linked to another Class II Fast Ethernet stack in the same collision domain. In the basic configuration, the 10Mbps and 100Mbps segments are separate but can intercommunicate. Because each unit has built-in switch, it can intercommunicate in a stack of up to four units.

An add-in module is also available, providing a 100BASE-FX connection. The hub in this series each has one slot for a slide-in module.
