About the 10T Hub Family
TheAsanté™ 10T Hub is a hardware device that lets you create high-speed
Ethernet networks over ordinary,unshielded twisted-pair (UTP),telephone
wire. The 10T Hubs are locw-cost,easy to use devices which do not require
complicated network management and are best suited to build small to
medium size networks or subnetworks of 50 nodes or less.Asanté also has a
line of intellegent hubs which offer powerful network management capabil-
ity.
10BaseT is a standard defined by the Institute of Electrical and Electronic
Engineers (IEEE).This standard defines how Ethernet components interact
with each other on LocalArea Networks (LANs) constructed of UTP.This
chapter introduces the 10BaseTAsanté 10T Hub and describes the contents
of the product package.It also provides information about additional
10BaseT products you may need to use with theAsanté 10T Hub.
AsantéTechnologies is committed to providing you with reliable products
and excellent technical support.Please feel free to callAsanté,or write us
with any questions,concerns,or suggestions.You can also reach us on-line
throughAppleLink at the address:ASANTE.

AboutThis Manual
This manual is divided into four chapters and four appendices:
Chapter 1,“Planning a Network Installation”on page 1-1 explains some
important considerations when designing and planning your network,and
provides the foundation for building reliable,easily managed,and expand-
able LANs.This is where to begin if you are not an experienced network
installer.
Chapter 2,“Installation”on page 2-1 shows you how to install the compo-
nents of anAsanté 10BaseT network.It tells you in detail how to configure
theAsanté 10T Hub,either as a stand-alone unit or within a larger network
with multiple hubs.
Chapter 3,“TroubleshootingYour Network”on page 3-1 describes how to
interpret the 10T Hub LEDs and how to troubleshoot common network
anomalies.
AppendixA,“CableWiring Diagrams”on pageA-1 covers the pin assign-
ments for the RJ45 connector and theAUI connector on the 10T Hubs.It
also details the media used in Ethernet networking.
Appendix B,“Mounting the Hub”on page B-1 provides simple instructions
for wall-mounting your hub.
Appendix C,“Technical Specifications”on page C-1 provides all technical
specifications for the hub family.

About 10BaseT
About 10BaseT
Twisted-pair Ethernet,as defined by the IEEE 802.3 specifications,is called
10BaseT.This is the latest development in the Ethernet evolution and repre-
sents a tremendous leap in networking technology.Because 10BaseT uses
regular twisted-pair (UTP) telephone wire,it decreases the cost of network-
ing.It’s also simple to install because it uses the same RJ45 jacks as your tele-
phone system.
Unlike thick and thin networks,which are arranged in a linear or “bus”
topology,10BaseT networks are arranged in a“star”configuration,in which
network nodes are connected like spokes in a wheel.A star configuration is
more reliable because each“spoke”is isolated and can’t affect the other
nodes if it runs into trouble.

OtherAsanté 10BaseT Networking
Products
To connect your personal computers and other network devices to a 10T
Hub,you will need a 10BaseT 10-compatible internal or external adapter for
each computer. AsantéTechnologies provides a complete line of network
interface cards for PCs and the Macintosh,as well as a 10T,BNC,or fiber
MAU. AllAsanté products support the latest IEEE specifications.

Planning a Network Installation
BeforeYou Start
An efficient network that will serve your long-term needs requires thorough
planning.This chapter discusses some of the topics that are important in the
early stages of network development.The topics are arranged in chronologi-
cal order.You should read this entire chapter to get an overview of the
details involved in planning your network.
To help you understand how devices in a building can be networked,con-
sider how buildings are wired for telephone service.Buildings are usually
wired for telephones in a star topology:wires run from one or more central
locations called wiring closets to wall jacks in each office.
With 10BaseT,this installed telephone wire can often be used for local area
networks.This makes installation and maintenance much simpler and less
expensive.
A small building may have only one wiring closet;large buildings often have
multiple wiring closets which are interconnected.Multi-story buildings usu-
ally have at least one wiring closet on each floor.The wall jacks on a floor are
connected to the wiring closet(s) on that floor.The wiring closets in a multi-
story building are often connected in a hierarchy.For example,a ten story
building might have a main wiring closet in the basement connected to ten
satellite wiring closets (one on each floor).
The 10T Hubs are well suited to build networks or subnetworks of 50 nodes
or less.If you plan to implement a large network with hundreds of devices,
you may consider investing in theAsanté intelligent hubs and a consultant to
help you design your network.
When you are ready to plan your installation,start here:

Page 1-3
Assign a Network Manager
Assign a Network Manager
A network manager initially coordinates the design and installation of the
network.Once the network is up and running,the network manager is
responsible for adding new users to the network and troubleshooting prob-
lems.For small installations,the network manager’s duties may only require
a few hours a week.For larger installations,the network manager’s position
may be a full-time job.

Page 1-4
Planning a Network Installation
Create a Network Map
A network map is a visual record of your network configuration.Create a
network map by copying a floor plan diagram and adding graphics repre-
senting devices and cabling.Modify the map as you change your plans,and
use the completed map as a guide during installation.It is a good idea to cre-
ate the map on a computer so you can easily modify it.
