This chapter introduces the 16/24/32 port dual-speed stackable
Ethernet/Fast Ethernet Hubs, as well as giving some background
information about the technology of the hubs use.
Product Description
The dual-speed stackable Ethernet/Fast Ethernet hubs described
in this manual are designed to allow easy migration and integra-
tion between 10Mbps Ethernet and 100Mbps Fast Ethernet, while
providing manageability and flexibility in cable connections.
These hubs can operate with either IEEE 802.3 10BASE-T con-
nections (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 re-
quired when a host is upgraded from 10Mbps to 100Mbps.
The hubs in the series, available in 16-port, 24-port and 32-port
models, can be stacked with up to four hubs in a stack. A stack of
four 32-port hubs gives a total of 128 Ethernet or Fast Ethernet
