Introduction
Chapter 1
Introduction
This chapter describes the SmartLAM STP and SmartLAM Plus UTP, and how you can use them in
your network.
About the SmartLAM STP and SmartLAM Plus UTP
The SmartLAM STP and SmartLAM Plus UTP are expansion modules that allow you to connect
token-ring stations to your SmartCAU Plus, SmartRAM STP, or SmartRAM Plus UTP. Each
SmartCAU Plus can attach to up to four SmartLAM units; each SmartRAM can attach up to two
SmartLAM units. Each SmartLAM has twenty connectors on its front panel for attaching lobe cables
to workstations on the desktop. By using up to four SmartLAM units in conjunction with a
SmartCAU Plus, you can connect up to eighty token-ring stations to your SmartCAU Plus.
The SmartLAM also incorporates intelligence that automatically switches out faulty cables and
equipment so that the network is disrupted as little as possible when faults occur.
The SmartLAM STP is for Shielded Twisted Pair (STP) media, and the SmartLAM Plus UTP is for
Unshielded Twisted Pair (UTP) media. This manual provides instructions on installing and using
both the SmartLAM STP and SmartLAM Plus UTP.
You can intermix the Madge SmartCAU Plus with IBM CAUs, and intermix Madge SmartLAM units
with IBM LAMs.

Installing the SmartLAM
This chapter describes how to install the SmartLAM.
Setting up the unit
Warning: The Madge SmartLAM does not contain any user-serviceable components. Do not open
up the units. If you attempt to do so, you may damage the components.
Before installing the unit, make sure that the environment meets the following requirements:
• the temperature remains between 10°C and 40°C (50°F and 104°F)
• the sides, front, and rear of the SmartLAM have a clearance of at least 50mm (2in) to allow
adequate air flow around the device. Leave enough clearance at the front and rear of the unit for
the cables that are to be connected. Do not bend these cables too tightly
• if mounting in a rack, the unit must be installed such that the rack remains stable
10008005.bk : 02-instl.fm5 Page 5 Tuesday, March 24, 1998 10:48 AM

Chapter 2 Installing the SmartLAM
To install your SmartLAM:
1 Do one of the following:
a If the SmartCAU Plus or SmartRAM is in a standard 19-inch wide rack, install the
SmartLAM beneath it.
b If the SmartCAU Plus or SmartRAM is not in a rack, affix the self-adhesive rubber feet
(supplied with the SmartLAM) to the underside of the unit, and place it on top of the
SmartCAU Plus or SmartRAM, or on top of any SmartLAM units that are already on top of
the SmartCAU Plus or SmartRAM. If you are installing the units on a shelf, make sure that it
can carry the weight of the units; the weights are given in Appendix A. You can stack up to
four SmartLAM units on top of a SmartCAU Plus or SmartRAM.
2 Connect the SmartLAM to the SmartCAU Plus or SmartRAM. There are two cables supplied
with the SmartLAM. Connect one end of each of the cables to the Expansion Unit connectors on
the rear of the SmartCAU Plus or SmartRAM, and connect the other ends to connectors on the
SmartLAM. Ensure that you connect the 25-way D-type connectors to the 25-way Expansion
Unit connectors, and that you connect the 9-way D-type connectors to the 9-way token-ring
connectors. Ensure that the 25-way and 9-way connectors of each SmartLAM are attached to the
same port number on the rear of the SmartCAU Plus or SmartRAM. The position of the
connectors on the SmartLAM are shown in Figure 2.1.

100-080-05 7
Installation
Figure 2.1 The location of the connectors on the rear panels
Note: You can intermix Madge SmartCAU Plus, SmartLAM STP, and SmartLAM Plus UTP units
with IBM CAUs and LAMs. The IBM CAU has two sets of numbered D-type connectors on its rear
panel. The procedure for attaching the LAM cables is the same as that for a Madge SmartCAU Plus.
An IBM LAM has two cables: one 25-way cable and one 9-way cable. The procedure for attaching an
IBM LAM to a Madge SmartCAU Plus is the same as that for a SmartLAM.

Note: To connect a SmartLAM Plus UTP to an IBM CAU, attach an external media filter to the
IBM CAU.
Note: When attaching a SmartLAM Plus UTP and a SmartLAM STP to the same SmartCAU Plus,
SmartRAM, or CAU, make sure the SmartLAM Plus UTP is upstream of the SmartLAM STP.
3 Connect the lobe cables to the ports on the front of the SmartLAM. Token-ring networks are
resilient to the temporary disruptions to network signals that occur when nodes are inserted into
and disconnected from the network. You do not need to switch off a Madge SmartCAU Plus
when connecting and disconnecting cables.
Note: Ensure that you tighten the screws at the cable ends.
Node counts
Madge token-ring equipment supports a maximum of 260 nodes on a single ring. A SmartCAU Plus
contains three nodes in the internal circuitry. Take these nodes into account when calculating the
number of stations that can be connected to the ring. Each SmartCAU Plus reduces the maximum
number of nodes by three. Each SmartRAM reduces the maximum number of nodes by one.

Chapter 3
Using the SmartLAM
This chapter describes how to use the SmartLAM.
In this chapter:
• Viewing the port status
• Using the SmartLAM with a SmartCAU Plus
Viewing the port status
The front panel of the SmartLAM has ports for the connection of lobe cables. Above each port on the
SmartLAM are two LEDs. The LED on the left is green and the one on the right is red.

Chapter 3 Using the SmartLAM
Using the SmartLAM with a SmartCAU Plus
Stack status indicators
Although the SmartLAM reports the status of the ports, it is the SmartCAU Plus that provides
management features and information about the Expansion Units connected to it. On the front panel
of the SmartCAU Plus are stack status indicators. These are a set of four bi-color LEDs that indicate
the status of the four Expansion Units that may be connected to the SmartCAU Plus. Alternatively, it
is possible to connect a single node to a SmartCAU Plus in place of an Expansion Units. In such a
case, the status LED indicates the status of the connected lobe. The following table explains how
the LEDs indicate the status of the Expansion Units attached to a SmartCAU Plus.
Table 3.1 Port LEDs
State of the port LEDs: Status of the port:
Both LEDs off The port is enabled, but no node is inserted
Left LED steady green A node is correctly inserted
Left LED flashing green The port has been disabled by a management program
Right LED flashing red An error has been detected. This may be a fault in the lobe cable or
an error with the node, for example, an incorrect ring-speed setting
LEDs flashing alternately A management program is identifying the port

Port status messages
The LCD on the front panel of the SmartCAU Plus can display a variety of status screens. Four of
these give information about each of the four stack ports. To select a different screen, use the paddle
switch next to the LCD. To move to the next screen, flick the switch downwards. To move to the
previous screen, flick the switch upwards.
If an Expansion Unit or a single station is connected, the LCD displays its type, and the number of
faulty ports (for IBM LAMs a single number is given; for Madge SmartLAM units, the number of
ports that are disabled due to a connected adapter being set to the wrong ring speed is shown
separately from the number of ports reporting other types of fault).
Table 3.2 Stack status indicators
LED status Meaning
Off No Expansion Unit (or single node) is connected to this port
Steady green An Expansion Unit (or single node) is connected and is working correctly. Note
that an Expansion Unit on which one or more ports have been disabled is
considered to be working correctly
Flashing red A fault has been detected. The fault may be with the Expansion Unit itself or the
cabling between the Expansion Unit and the SmartCAU Plus. Check that the
Expansion Unit cables are properly connected to the SmartCAU Plus. Similarly, if
a single node is connected to the port, the fault could be either with the node
itself or with the lobe cable between the SmartCAU Plus and the node. In most
cases, additional information about the probable cause of the fault is available on
the LCD

Lobe cable lengths
UTP
Two different categories of UTP cable are commonly used, which support different lengths of lobe
cable. The better “data grade” UTP cable is Category-4 or Category-5 cable, and includes AT&T
2061 and Northern Telecom BDN. The ordinary “voice grade” UTP cable is Category-3 cable, and
includes IBM Type-3, AT&T DIW and Belden Type-1154A. Madge strongly recommend the use of
Category-5 cable wherever possible; operation at 16Mbps on Category-3 cable is installation-
dependent and the cabling distance cannot always be guaranteed. Approximate lobe cable distances
supported on UTP cables are shown below. We carry out our testing with Madge and IBM 16/4
token-ring adapters. Other vendors adapters may not support the cabling distances given below.
Table B.2 Lobe cable distances supported on UTP cables
Cable type 4Mbps 16Mbps
Category 3 120m See note below
Category 4/5 160m 100m

Note: We recommend that you do not use Category-3 UTP cabling on a 16Mbps token-ring.
However, you may be able to use well-installed Category-3 UTP cabling over a short distance (50m
maximum). Temperatures above 20°C will reduce this distance, and you may need to select specific
pairs of cable to achieve reliable operation of the ring. We recommend you use the two pairs with the
highest twist rate as the two token-ring pairs. The twist rate measures how tightly the two wires in
one pair are twisted, and is usually measured in twists per foot. Category-3 cable has approximately
three to four twists per foot, Category-5 cable has approximately twenty twists per foot.
STP
Lobe cable distances supported on STP cables are shown below.
Table B.3 Lobe cable distances supported on STP cables
Cable type 4Mbps 16Mbps
Type 1 375m 145m
Type 2 375m 145m
Type 6 250m 95m
