Introduction
The FriendlyNet Dual-speed Hub
Dual-speed hubs are a compact, flexible solution for workgroups or
SOHO (Small Office/Home Office) LANs (Local Area Networks).
The Asanté hub’s compact design makes it ideal for desktop placement or rack
mounting.
The
Dual-speed
100Mbps modes. These transmission speeds are automatically detected or can
be set manually on ports one and eight.
The stackable feature allows you to join up to three hubs, thereby forming a
network of up to 48 ports.
The FH208B/FH216B Base Hubs allow for simultaneous transmission
between 10Mbps and 100Mbps domains. When hubs are stacked, a FH208B
or FH216B
FH216 are expansion hubs and can be joined through the back panel cascade
connectors.

Performance Features
The Dual-speed FriendlyNet Hubs offer the following features:
10/100Mbps Auto-sensing
In Auto-sensing mode, hubs will automatically detect whether the network
station is connected for 10Mbps or 100Mbps transmission speed.
Three-Speed Mode Setup (Ports 1 and 8 Only)
Three-speed mode set up is useful for special network environments such as
10Mbps or 100Mbps only. By setting the DIP switches, the MDI-II ports can
operate in one of three speed modes:
❑
Auto-sensing mode
100Mbps mode
❑
❑
10Mbps mode
To manually set a speed for your network, refer to “Setting up Forced Speed for
the MDI-II Ports” in Chapter 2.
The Base Unit (Bridge)
The FH208B and FH216B Ethernet Hubs include an internal, automatic
switch for
bridging

Introduction
entire stack. The bridging operation is indicated by the illuminated Switch
LED.
▲
Important!
Without the Base Unit, data cannot pass
between these two domains.
▲
Important!
Do not connect two Base Units together.
Network Ideas and Concepts
FriendlyNet Stackable Ethernet Hubs allow for a variety of network design
configurations. Here is one example.
Stand-alone or Single Star Topology
In a stand-alone network, the
resources,
such as workstations, printers, etc., are
connected by a single hub. This is called star topology because the resources
form multiple
points
emanating from a single hub. In the example shown in
Figure 1-5, seven workstations are connected to one FriendlyNet 8-Port Hub.
