Introduction
Introducing the FriendlyNet Ethernet Hub
Thank you for purchasing theAsanté FriendlyNet 5-port or 8-port
Ethernet Hub.
The FriendlyNet Hub provides your network with up to 5 or 8
UnshieldedTwisted Pair (UTP) port connections.
5-port FriendlyNet Hub
The 5-port FriendlyNet Hub (FH10T5) comes with five RJ-45 ports
for connecting to 10Base-T network stations and one UPLINK
(cascade) port for connecting to another hub.
Figure 1-1 5-port FriendlyNet Hub,front and rear views
8-port FriendlyNet Hub
The 8-port FriendlyNet Hub (FH10T8) comes with eight RJ-45
ports for connecting to 10Base-T network stations and one
UPLINK (cascade) port for connecting to another hub.

Introduction
Page 1-2
The FriendlyNet Hub constantly monitors its ports for signal qual-
ity and automatically partitions a port producing noise or exces-
sive collisions; the device automatically reconnects when the
error condition is cleared.
The FriendlyNet Hub automatically truncates data packets that
exceed the maximum length for IEEE 802.3,preventing a device
from blocking the network by transmitting continuous data
streams or extra long packets.
Features
❏ Plug-and-Play installation.
❏ Connects up to five (5-port hub) or eight (8-port
hub) 10Base-T devices.
❏ Accommodates cascaded bus or daisy-chain Ether-
net topologies;up to 98 ports can be easily daisy-
chained per Ethernet segment (using 8-port hubs).
❏ Provides preamble regeneration,single retiming and
restoration,and jabber function for automatic parti-
tioning.
❏ Contains power and collision LEDs as well as
individual port Link/Activity LEDs to aid network
diagnosis and management.
❏ Compact design;install on desktop or mount on
wall.

Installation
Before You Start
▲ Important: Check theAC power line voltage
used in your area.TheAC power adapter
included with your hub must match the power
supply voltage used in your area.
❏ AC input power : equal to theAC power
voltage used in your area
❏ DC output power :5V 800mA
Installation Overview
Before you connect the FriendlyNet Hub to other devices,review
the following guidelines:
❏ Make sure the network cable length is less than
100 meters .
❏ Use a straight-through twisted pair wire.
❏ When connecting two hubs together (cascading
hubs),make sure the primary hub’s IN port is
connected to the secondary hub’s UPLINK port.
❏ Network cable segments can be connected to,or
disconnected from,the FriendlyNet Hub while
the power is on.
∆ Note: The installation diagrams in this section
pertain to both the 5-port and 8-port FriendlyNet
Hub.

10Base-T Station to Hub Connection
To connect a 10Base-T network station to the FriendlyNet Hub,
follow the instructions and diagram below.
▲ Important: Use a straight-through network
cable. Make sure the length of the cable between
the station and hub does NOT exceed 100 meters
(including all patch cables and cross-connect
wires).
Network cable segments can be connected to,or
disconnected from,the hub while the power is
on.

Hub to Hub Connection
To connect two FriendlyNet Hubs,follow the instructions and dia-
gram below.
▲ Important: Use a straight-through network
cable.Make sure the distance between the two
hubs does NOT exceed 100 meters.
FriendlyNet Hubs may be interconnected as long
as the path between any two network stations
does not exceed FOUR hubs and FIVE cable seg-
ments.

Multiple Hub and Station Configuration
To connect multiple FriendlyNet Hubs and Ethernet network sta-
tions,follow the guidelines and diagram below.
▲ Important: Your Ethernet network configura-
tion must comply with the IEEE 802.3 standard.
❏ The maximum number of cable segments
between any two network stations is FIVE.
❏ The maximum number of hubs between any two
network stations is FOUR.
❏ At a maximum,you may install up to 16 8-port
hubs and connect up to 98 network stations in a
10Base-T configuration.

Wall Mounting the FriendlyNet Hub
The FriendlyNet Ethernet Hub can be mounted to a wall or to the
surface of a countertop using the screws included with the hub.
To mount the hub to a wall or countertop:
1
Screw one of the enclosed 1/2-inch screws into a
wall (or countertop),leaving approximately 1/4
inch of the screw’s threads exposed.
2
Hang the hub on the wall (or secure it to the
countertop) using the keyholes on the bottom of
the hub. See Figure 2-4.

LED Indicators
LED Indicators
The FriendlyNet Ethernet Hub contains the following LEDs:
❏ Power LED
❏Collision LED
❏Link/Activity LED for each port
Figure 3-1 FriendlyNet (5-port) Ethernet Hub LEDs
Power LED
The green PWR (power) LED on the hub’s front panel illuminates
when the hub is receiving power and is turned on.
Collision LED
The yellow COL (collision) LED on the hub’s front panel illumi-
nates when two or more stations on the network attempt to trans-
mit packets simultaneously.
Collisions are normal in Ethernet networks. Excessive collisions
may indicate that your network is congested.

Ethernet Configuration
Ethernet Configuration
This section describes the star topology Ethernet configuration. It
is intended to help you make the proper connections for your
Ethernet networking system.
Star Topology
A 10Base-T Ethernet network is configured in a star topology (see
Figure A-1).
A star topology is a physical topology in which multiple nodes are
connected to a central component,generally known as a hub or
repeater.
FigureA-1 Star topology
A star topology is easy to troubleshoot,since each segment sup-
ports only a single attachment. A star topology must comply with
the IEEE 802.3 connection rules.
