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 represents a tremendous leap in networking technology. Because 10BaseT uses regular twisted-pair (UTP) telephone wire, it decreases the cost of networking. It’s also simple to install because it uses the same RJ45 jacks as your telephone 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.

Planning a Network Installation
Before You 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 chronological 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, consider 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 usually 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 multistory 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 the Asanté intelligent hubs and a consultant to help you design your network.
When you are ready to plan your installation, start here:
Page 1-2
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 problems. 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 1-3
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 representing 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 create the map on a computer so you can easily modify it.

Planning for Network Operations
Planning for Network Operations
Create a Network Log
A network log is a record of the names of devices, locations of wire pairs, wall-jack numbers, and other information about the network. A simple network log may contain the name, description, node number, and 10T Hub port number for each device on the network. A more detailed log may contain the serial number of each device, the network number, and more. Consider creating a network log to use as a reference when you are installing and managing the network. An up-to-date network log ensures that records of network equipment are always readily available. Having a complete written record of your network will make troubleshooting easier.
Consider Future Expansion
As your network needs grow, your network should also grow. Hasty additions to your network make network maintenance difficult and time-consuming. Plan to install more cabling than you think you will need. With adequate preparation, adding another device to the network can often be as simple as plugging in another network connection.
Determine Application Needs
Think about how people on the network plan to use it. Will they be occasionally printing, exchanging mail, or transferring files? Will some users regularly access a multi-user database, transfer large graphics or CAD files, or launch applications from a server? Depending upon your users’ application needs, you might want to break your network into smaller clusters (segments) using bridges and routers.
Determine If You Can Use Existing Wiring
The physical limitations and regulations on the use of your building’s wiring can greatly affect your choice of network layouts. Have the building manager or a telephone installer determine whether you can use existing wiring in your office. In general, you can use existing wiring if you have two unused wire pairs (four wires total) going to each network node.
There are four fundamental rules you must follow:
❏ The wire must be 24-gauge, unshielded, twisted-pair, solid-conductor.
Page 1-5
Planning a Network Installation
❏
❏
❏
You must use solid copper (not stranded) twisted-pair wiring. You can identify twisted-pair wire by alternating color bands: white/blue, blue/white, white/orange, orange/white, and so on.
Use approved building wiring standards or consult a professional
The maximum twisted-pair link-length from hub to transceiver, including the RJ-45 cable, is 100 meters (328 feet).
If the wire in your building does not meet the criteria specified above, or if workstations are needed where no wire exists, you need to install new wire.
The above list is a brief overview, but this wire should conform to the IEEE
802.3 Type 10BaseT 10 specification, Section 14.4, “Media Specification.”
Basically, this is ordinary 24-gauge, unshielded, twisted-pair, solid-conductor cable.
Decide Where to Put the 10T Hub
You need to place the 10T Hub in a location so that the distance of wire between the 10T Hub and any potential workstation is no greater than 100 meters (328 feet).
Place the 10T Hub in an area that is readily accessible for installation and maintenance. The 10T Hub must also be placed near an AC outlet. If you are wiring a building which has multiple wiring closets, you may want to place
10T Hubs in both the main wiring closet and satellite wiring closets.
The temperature and humidity requirements must fall within those specified in Appendix A, “Technical Specifications.” Do not place the 10T Hub near sources of electrical interference, such as motors or heavy-current switches.

Plug and Play Installation
Plug and Play Installation
The Asanté 10T Hubs are designed for plug and play installation. Before you connect the hub to other devices, there are several things you should keep in mind:
❏
❏
❏
❏
❏
When connecting two Ethernet devices (such as a hub,
Ethernet adapter, or 10BaseT MAU) together, you must make sure that the total modular cable length is not greater than 100 meters.
When you connect two hubs together using the 10BaseT ports, make sure the “OUT” port of one hub is connected to the “IN” port of another hub.
Network stations on the thin coaxial cable or thick cable segment can also be connected to the hub.
Network cable segments can be connected to or disconnected from the hub while the power is on. Plugging in or removing network cable segments while the hub is operating will not interrupt the operation of the hub.
When you install the hub, you must avoid dusty locations, and avoid electromagnetically noisy areas.

Do the following steps to connect a thin Ethernet configuration.
1 According to the IEEE 802.3 rules, a thin Ethernet segment supports 30 connections over a distance of 185 meters (607 feet).
2 A BNC T-connector is used to connect the thin Ethernet cable.
This is a simple way to connect multiple hubs together to form a large network.
Other workstations with thin Ethernet adapters can also connect to the cable segment.
3 Make sure both ends of the thin Ethernet segment are terminated by a 50
Ω
terminator and are grounded.
Only one end can be grounded and this must be according to the
IEEE specification
4 Connect the T-connector onto the BNC connector and twist the
T-connector sleeve to lock the connection, as shown in

Only one shared port is available on the 10T Hub/8 for either BNC or AUI connection. This port is equipped with two connectors: a BNC connector and an AUI connector. The hub autosense circuit can detect which connector is in use and no switch needs to be set. Just make sure that only one of the connectors is connected.
There is no such restriction on the 10T Hub/12. Both the BNC port and the AUI port can be used at the same time.

Connecting Multiple Hubs for a Larger
Network
You have several choices when connecting networks with more than one hub:
❏
❏
❏
❏
Use unshielded twisted-pair cable to connect the “OUT” port of port 1 to the “IN” port of another hub in a hierarchical topology.
Use the BNC port on the hub to connect to a thin Ethernet backbone
Use the AUI port to connect to a thick Ethernet backbone
Use the AUI port and an external MAU to connect to a media of your choice. For example, fiber optic cable.

Interconnecting via the UTP Port
Interconnecting via the UTP Port
To interconnect multiple star networks using the UTP ports:
1 Use two, ISO 8877, 8-pin, modular jacks (RJ45) on a length of twisted-pair wire (no longer than 100 meters) that is 24-gauge, solid-conductor, unshielded twisted-pair.
2 Insert one jack into the IN port of one hub (e.g. , Port 9). Insert the other jack into the OUT port of another hub.
Figure 2-5 Sample Network of Two 10T Hub Units
The two hubs are connected with a twisted-pair cable from the “OUT” port of one hub to the “IN” port of the other hub.
Each workstation connected to the hubs requires an Ethernet adapter. A
10BaseT MAU can be used to convert an older Ethernet card which supports thick cable to support twisted pair cable. In this diagram, the Macintosh computers have an internal Ethernet card, such as the Asanté MacCon3 cards, and the PCs have a TP-MAU, such as the Asanté 10T MAU.

Installation
Wiring RJ21 Installations
The 10T Hub12 provides an additional RJ21 connector to provide an alternative way to wire the workstations to the hub. Instead of having twelve cables going to the RJ45 ports on the hub, a single cable with 25 pins of twisted pair wires inside and RJ21 connectors at the ends can be used instead. Thw twisted pairs of wires are distibuted to the workstations through a punchdown block. Follow the instructions below.
1 Install the Asanté 10T Hub and network punchdown block in the wiring closet, and interconnect them with an Amphenol cable.
The 50 rows of pins on a network punchdown block can be logically grouped into sets of four rows. Each set represents the connections necessary for one branch or port of the network. A network punchdown block has 50 pins, therefore containing enough rows of pins for 12 ports. The remaining two rows of pins are reserved for future use.
2 Cross connect the wires from the network punchdown block to the distribution punchdown block.
3 Run two pairs of 24 guage wire from the network punchdown block to a RJ45 wall jack near each workstation. The maximum distance between the punchdown block and wall jack is 100 meters (328 feet) using 24 AWG wire.
▲
Keep careful track of the wall jack wiring. When you later return to the wiring closet to wire the punchdown block, you must be able to exactly determine the wall jack and pin destination of each wire.
When wiring the wall jack, be sure that you wire the terminal posts which correspond to pins 1, 2, 3, and 6 (see Figure 2-8 on page 2-13). This sequence repeats itself for the remaining ports
(four rows per port) on the punchdown block.

RJ45 has eight pins. Four of these pins are used for the network: pins 1, 2, 3, and 6. Connect one pair of wires to pins 1 and 2 on the RJ45, then connect this wire pair to rows 1 and 2 on the punchdown block. Connect a second pair of wires to pins 3 and
6 on the RJ45, then connect this wire pair to rows 3 and 4 on the punchdown block. Be sure you do not reverse the polarity of the wire pair since this will cause that network branch to fail.

Troubleshooting Your Network
Before You Start
Testing and monitoring your network’s status is done with the aid of the
LEDs on the hub, the network interface card, or the 10TMAU. In general, the
LEDs give information about the status of a particular unit or function. This section covers how to read the LEDs when testing your installation and during normal network operation.
The hub does not require any routine maintenance because it doesn’t contain any fans or other mechanical devices on which its operation depends. If you cannot identify and correct a fault using the testing procedures described below, contact Asanté Technical Support. There are no user-serviceable parts in the Asanté 10T Hub.
Page 3-2
10T Hub Ch 3 Page 3 Thursday, August 22, 1996 4:27 PM
Interpreting the Hub LEDs
Interpreting the Hub LEDs
When you first turn on your Asanté 10T Hub, all the LEDs switch ON while the hub goes through a series on internal diagnostics ensuring its reliable operation. After the diagnostics have been completed, each LED indicates a different condition. Below is a description of each LED.
Table 3-1 Hub LED Description
LED Name
Power/Traffic
Link Status
Functional Definition
ON indicates that power is applied to the hub.
When there is network traffic, this LED will blink on and off to indicate traffic.
Each LED indicates the link status of the corresponding port.
A steady green LED indicates that the
Link Status test has passed and the connection from the workstation to the hub is good.
No light indicates that the connection may be broken. In order to be sure that the connection from the hub to the workstation is also good (there are two pairs of wires in the cables), the link status light on the adapter card should also be checked.
Page 3-3
10T Hub Ch 3 Page 4 Thursday, August 22, 1996 4:27 PM
Troubleshooting Your Network
Testing Your Installation
After your installed wiring is connected, you need to begin testing the installation by connecting two network devices that communicate with one another, such as one workstation and one file server. When you have one pair of devices working correctly, you will have verified that the hub functions and will know that the link between the workstation and the file server is complete.
If the two devices cannot communicate, follow the procedure described below.
1
2
Make sure the power indicator on the hub is on.
Make sure that the wiring is correct between the hub and the device connected to it and that both have Link Status LEDs on.
3 Make sure that all individual devices can communicate with one another without the hub.
You can check this out by forming a network of only two devices. Use a cross-over cable to connect the two devices without using hub. Directions for making a cross-over cable are in the appendix of this manual.
4 If all devices communicate, you now concentrate on eliminating wiring or hub malfunctions.
Following are some suggested areas to check, depending on what the problem is. If the problem persists, call Asanté Technical Support.
Page 3-4
10T Hub Ch 3 Page 5 Thursday, August 22, 1996 4:27 PM
Common Problems Found in the Hub
Common Problems Found in the Hub
Link Status LED is off.
Probable cause is a twisted-pair connector is not making contact. Check all RJ45 connectors.
Can also be caused by incorrectly wired twisted-pair cable. Compare wiring to the diagram in the appendix of this manual.
BNC port doesn’t have proper termination.
Terminate the BNC port.
Following are suggested areas to check depending on what the problem is.
If the problems persist, call Asanté Technical Support.
Common Wiring Problems and Solutions
❏ Stranded modular connection wire is used.
Use only solid connector wire.
❏ Wire improperly configured.
Make sure wire follows guidelines as defined in “Determine If You Can Use Existing Wiring” on page 1-5 of this manual.
Common Workstation Problems and Solutions
❏ Broken or improperly connected AUI cable
Check connections, continuity, and impedance.
❏ Network interface card hardware not configured properly
❏ Proper application software not running on workstation to provide connection (i.e., make sure you are running
TCP/IP software when talking to a UNIX host system).
❏ Workstation not operating properly
Take workstation to an authorized service center to ensure proper operation.
Common Problems Found in the Hub
❏ Power not connected to hub
❏ More than one cable wired between two hubs
Page 3-5
10T Hub Ch 3 Page 6 Thursday, August 22, 1996 4:27 PM
Troubleshooting Your Network
❏ Other workstations connected to hub, disrupting communcation of workstations being brought up
Remove the disrupting workstations or disable their links. Hub hardware failure is possible, but not likely if it passes the self-test.
