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

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.

The Auto-sensing capability allows Asanté Hubs to connect to 10Mbps and/or
100Mbps devices in your network. This section describes setting up network
configurations using a variety of devices.
10Mbps/100Mbps Speed Sources
By default, each port is set to Auto-sensing mode. The Asanté Hubs will detect
the correct 10Mbps/100Mbps speed to transmit information to connected
10Base-T or 100Base-TX devices.
The FH208 and the FH216 need two different speed sources to transmit
10Mbps or 100Mbps within two different domains. Therefore, two ports
connected to 10Mbps and 100Mbps are required.
▲ Caution! 10Mbps and 100Mbps information cannot be
transmitted between 10Mbps and 100Mbps domains.
If you want to transmit information between 10Mbps and 100Mbps domains,
a switching hub or a hub with an internal switch module such as the FH208B
Page 2-7
Installation
or FH216B is required. See “Connecting Ethernet H ubs and S witches” on page
2-12 for further information.
Forced speed also can be set to expand your network options. See “Setting Up
Forced Speed for the MDI-II Ports” on page 2-10.
Connecting W orkstations
To connect your hub to workstations or nodes:
1 Be sure each computer has either a 10Base-T or 100Base-
TX Ethernet Network Interface Card installed.
2 Connect one end of each UTP cable to the Ethernet
Card’s RJ-45 port in each computer.
❑ for 10Base-T use UTP Category 3 cable or better
❑ for 100Base-TX use UTP Category 5 cable
3 Plug the other end into one of the RJ-45 ports on the hub
as shown in Figure 2-12.
Figure 2-12 Connecting a Cable to a PC
◆ Note: The maximum length of cable between a hub and
device is 100 meters, including all patch cables and crossconnect wires.
4 Continue connecting workstations to the hub using UTP
cables to create a network as shown in the example in
Figure 2-13. Additional devices can be connected through
the MDI-II ports using straight through (UTP) cables.

Setting Up Forced Speed for the MDI-II Ports
Auto-sensing is the default mode. If the devices connected to the hub using the
MDI-II ports do not support Auto-sensing or if for other reasons you wish to
force the speed, set the DIP switches to one of the positions shown in Figure 2-
15. Note that forced speed can only be applied to the MDI-II ports. The DIP
switches will force either or both of the MDI-II ports into one of three modes:
❑ Auto-sensing — set the P ort 1 switches and/or Port 2 switches to the
down position

▲ Important! After changing the DIP switch settings, the
AC power to the unit must be cycled.
▲ Important! Ports 1 and 8 are individually shared with the
MDI-II ports. Therefore, when an MDI-II port is in use, its
nearest port (1 or 8) will be disabled.

Connecting Ethernet and Fast Ethernet Hubs
If your transmission speed is 10Mbps, connect 10Mbps devices using UTP
Category 3 cables. This enables sending/receiving to other 10Mbps devices.
The FH216 and FH216B include a Fast Ethernet MII connector on the rear
panel. You can connect a Fast Ethernet MII transceiver to this port. It is fixed at
100Mbps and half-duplex.
Page 2-10
Connecting Network Devices
Connecting Fast Ethernet Hubs
If your transmission speed is 100Mbps, using the same method, connect 100
Mbps devices using UTP Category 5 cables with RJ-45 plugs. This enables
sending/receiving to other 100Mbps devices.
▲ Caution! Hubs FH208 and FH216 function as ordinary
dual-speed hubs. Using these hubs,10Mbps information
can only pass to other 10Mbps devices and 100Mbps can
only pass to 100Mbps devices. To transmit information
between 10Mbps and 100Mbps simultaneously, use the
FH208B or FH216B.

Stacking Hubs and Cascade Connections
Up to three hubs may be connected within a stack. Three 8-port units will
provide up to 24 ports; three 16-port units will provide up to 48 ports.
Cascade Connectors
Connect hubs in a stack using Cascade Connector cables as shown in
Figure 2-17. When stacking hubs:
❑ Use a Cascade Connector cable to join hubs
❑ Maximum length of the Cascade Connector cables is eight inches
❑ No DIP switches should be set while joining hubs together
Page 2-11
Installation
Figure 2-17 Cascade Connector Cables
▲ Important! The Cascade In port should connect to the
Cascade Out port of another hub.
Connecting Ethernet Hubs and Switches
Switches enable simultaneous 10Mbps/100Mbps transmission. If you wish to
transmit information between 10Mbps and 100Mbps domains simultaneously,
use a hub with an internal switch module, also known as a bridge, such as the
Asante´ FH208B or FH216B. As an option, you may wish to use a stand-alone
or external switch in your network.
The requirements for implementing 10Base-T and 100Base-TX in a hub are:
❑ Separate 10Mbps and 100Mbps sources
❑ Two ports connecting to 10Mbps and 100Mbps
Dual-speed FriendlyNet Hub with Bridge
The Dual-speed FriendlyNet Bridge is a cost-effective alternative to external
switches. The Bridge serves as a transparent connection between hubs, devices
and workstations of different transmission speeds.
Stacking Hubs with the Bridge (Base Unit)
When including a base unit such as the FH208B or FH216B within a stack of
hubs the base unit may be placed anywhere within the stack. See Figure 2-18.
In this configuration, the devices in the network connected to MDI-II ports
and RJ-45 ports may be bridged. Non-bridged units in the stack configuration
serve as expansion hubs for the base unit.
▲ Important! Do not stack two bridge hubs together.
Page 2-12
Powering On the Hub
Up to three hubs may be connected together within a collision domain. When
stacking hubs:
❑ Use a Cascade Connector cable to join hubs
❑ Maximum length of the Cascade Connector cables is eight inches
▲ Caution! Place only one base unit in a network. More than
one bridge or switch in a network will generate network
looping.
