Introduction
FriendlyNet FH100TX8 and FH100TX16
Thank you for purchasing the Asanté FriendlyNet FH100TX8 or the FriendlyNet FH100TX16 Fast Ethernet Hub.
The FH100TX8 and FH100TX16 Fast Ethernet Hubs are 100Base-TX multiport repeaters designed for networks using Unshielded Twisted Pair (UTP)
Category 5 cable or Shielded Twisted Pair (STP) cable.
8-port Fast Ethernet hub
Figure 1-1 FriendlyNet FH100TX8 Fast Ethernet Hub — front panel
16-port Fast Ethernet hub
Figure 1-2 FriendlyNet FH100TX16 Fast Ethernet Hub — front panel
Each hub is simple to install and features power, link/receive, partition, and
utilization LEDs for easy monitoring of the hub and its ports.
For network expansion, each hub has an uplink port that makes it easy to
connect to another Fast Ethernet hub or hub stack.

Introduction
Network Reliability
To ensure network reliability, each hub monitors their ports for signal quality
and automatically disconnects stations transmitting excessive noise, reconnecting them when the problem is resolved.
The hubs automatically truncate data packets that exceed the maximum length
for IEEE 802.3u, preventing a device from blocking the network by transmitting continuous data streams or extra long packets.
The 8-port and 16-port FriendlyNet hubs are ideally designed for small- to
medium-sized 100Base-TX Fast Ethernet networks and comply with the IEEE
802.3u Fast Ethernet standard.
Features
❏ Works with Category 5 Unshielded Twisted Pair (UTP) or Shielded
Twisted Pair (STP) cable
❏ Connects up to 8 or 16 100Base-TX segments per hub; one of the
ports can be used as an uplink for connecting to another hub or
hub stack
❏ Automatically partitions ports to isolate port failures
❏ Easily mountable in a standard 19-inch equipment rack or on a
desktop
❏ Complies with the IEEE 802.3u Fast Ethernet Standard
❏ FCC Class A, CE Mark certification
Package Contents
❏ 8-port (FH100TX8) or 16-port (FH100TX16) FriendlyNet Fast
Ethernet Hub

Installation
Installation of the FH100TX8 or FH100TX16 hub consists of the following
steps:
❏ Plan your 100Base-TX network.
❏ Review cabling and voltage requirements.
❏ Connect your hub to network devices.
❏ Mount the hub in an equipment rack or prepare it for desktop
placement.
Planning 100Base-TX Networks
100Base-TX networks need to be planned out slightly different from 10BaseT networks because new hubs and new wiring configurations are necessary.
Follow the guidelines below when planning your 100Base-TX network configuration:
❏ 100Base-TX supports a maximum cable length (distance from a
network station to the hub) of 100 meters.
❏ The total network diameter (the maximum cable distance
between any two stations on the network) is 205 meters.
❏ Because 100Base-TX sends signals 10-times faster than 10Base-T,
the collision window (the time during which the network can
detect a collision between packets) is reduced to one-tenth the
duration of the 10Base-T collision window, making the maximum network diameter smaller.
❏ Only two hubs can be cascaded together (in a repeater envi-
ronment, 100Base-TX allows only a single layer of cascaded
hubs). See Figure 2-1.
