Introduction
16/24 Port 100/10M Dual-Speed Hub is designed to allow easy migration
and integration between 100Mbps Fast Ethernet and 10Mbps Ethernet. It
means 100Mbps and 10Mbps users can communicate in the same network
environment. It also offers the simplest way to upgrade your network so that
you can connect all of your Fast Ethernet and Ethernet hosts to any hub in the
series, without any rewiring requirement when a host is upgraded from
10Mbps to 100Mbps.
16/24 Port 100/10M Dual-Speed Hub supports one optional 100BASE-FX
Fiber Optic Module (ST/SC-type) that can deliver a low cost yet high speed
data link over fiber, allowing you to expand your networks further than ever
before. The optional Fiber Optic Module can exceed the 100-meter limitations of Cat 5 UTP/STP cables, providing greater security and reliability.
The Dual-Speed Hub can be stacked up to 3 units for a total port count of 48
(or 72) connectors for workstations or servers.
n Powerful Performance
As your network grows, you need more bandwidth to stay productive and
competitive. Whether you are building a new network or expanding an
existing one, the Dual-Speed Hub gives you more power with the ease of
plug & play. A full 100Mbps link can be provided to all devices on the
LAN if required.

n Dual-Speed Hub
The Dual-Speed Hub has built-in bridge module, thereby providing
100Mbps and 10Mbps users transparent access to the same network, even
though the 100Mbps and 10Mbps segments are separated.
n Expansion bridge port function
The Dual-Speed Hub with the internal switching function can be
Auto-configured either Master mode or Slave mode. The master mode
occurs when a stack in port isnt connected on the rear panel. The slave
mode occurs when a stack in port is connected on the rear panel.
Therefore, the Dual-Speed Hub changes to either Master mode with one
expansion bridge port ( # 1 port ) or slave mode with two expansion bridge
ports ( # 1, 9 ports for 16 Port Dual-Speed Hub ; # 1, 13 ports for 24 Port
Dual-Speed Hub ) automatically depends on stack configuration.
n Optional Fiber Optic Module
The Dual-Speed Hub includes a module slot which can be
configured with fiber module to expand the network size and to connect
within a fiber cabled environment. With this optional fiber optic module
installed, data transmissions are not affected by electrical interference and
the distance of the link can be 208 meters to another hub or 412 meters
(2000 meters in FDX mode) to a switching hub.
