Introduction
This chapter describes the Madge™ Collage™ 700 series Backbone ATM Switches and the option
Modules they support.
About the Backbone ATM Switch
This guide provides information about the software features available for the Collage 700 series
Backbone ATM Switches.
Currently, there are two switches in the Collage 700 series:
• the Collage 740 Backbone ATM Switch
• the Collage 750 Backbone ATM Switch
These are high-performance Asynchronous Transfer Mode (ATM) switches that are designed for
building and campus backbone applications, high-performance centralized servers, and power-user
environments. Its advanced architecture, incorporating Madge Cellrunner™ switching technology,
can support very high traffic loads with no data loss or breaks in communication. These switches also
implement LAN emulation components. LAN emulation enables legacy LAN applications to use a
transparent ATM transport medium, so endstations on existing Token Ring and Ethernet LANs can
communicate with ATM endstations.
Note: Any Collage 700 series switch that has the Collage 751 Switch Fabric installed, is referred to as
a Collage 750 switch.

Chapter 2
Installing option modules
To make sure you do not injure yourself or damage your Madge product, always refer to the
installation manual and the Madge Safety Guide (part number: 100-002) before installing hardware. If
you are in doubt, contact your customer service representative.
The Collage 700 series switches are chassis-based and are provided with a PSU, a Processor, and a
Switch Fabric pre-installed. The pre-installed modules perform functions vital to the integrity of the
switch, and can be replaced with modules of the same type should they develop a fault. The switch
chassis also supports the installation of option modules into the five option slots, numbered 1 through
5. You need to install at least one option module that carries ATM traffic to communicate with other
ATM devices.
This chapter provides guidelines for inserting or removing option modules; refer to the switch
hardware installation guide for information about inserting and removing the pre-installed modules.
Warning: Electrical current from power, telephone, and communications cables is hazardous. To
avoid an electrical shock when installing or moving the product or devices attached to the product,
connect and disconnect cables as shown in the Madge Safety Guide (part number: 100-102).
When you install an option module, you may need to download new code to the switch. To find out
whether your switch software supports the option module that you plan to install, refer to the
Collage 700 Backbone ATM Switch User Guide (part number: 100-324).

Installing
optionmodules
Electrical considerations
This section provides important information about working with electrical equipment and
preventing electrostatic discharge. This section also provides information about online insertion and
removal, which is also known as hot swapping.
Electrical equipment
Follow these basic guidelines when working with any electrical equipment:
• Before beginning any procedures requiring access to the interior of the unit, locate the
emergency power-off switch for the room in which you are working.
• Before moving the unit, disconnect all power and external cables.
• If potentially hazardous conditions exist, do not work alone.
• Never assume that power is disconnected from a circuit; always check.
• Do not perform any action that creates a potential hazard to people or makes the equipment
unsafe.
• Carefully examine your work area for possible hazards such as moist floors and ungrounded
power cables.
• Only connect the product to a correctly wired and earthed receptacle.
Preventing electrostatic discharge damage
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are
improperly handled, results in complete or intermittent failures. The Collage option modules
comprise a printed circuit board that is fixed to a metal carrier. Electromagnetic interference (EMI)
shielding and connectors are integral components of the carrier. Although the metal carrier helps
protect the board from ESD, whenever you handle option modules you must use a preventative
antistatic strap. Handle the option module by the metal carrier and the edges of the module only;
never touch components on the board or the connector pins.

Observe the following guidelines to help prevent ESD damage:
• Always use an ESD-preventative wrist or ankle strap and ensure that it makes good skin contact.
Hazard: For safety, periodically check the resistance value of the antistatic strap. The measurement
should be between 1 and 10 mega Ohms.
• Connect the equipment end of the strap to the metal case of the Collage switch.
• Handle the option module by the metal carrier and the edges of the module only; never touch
components on the board or the connector pins.
• Place a removed option module on an antistatic surface or in an antistatic bag. If the component
will be returned to the factory, immediately place it in an antistatic bag.
• Avoid contact between the option module and clothing. The wrist strap only protects the board
from ESD voltages on the body; ESD voltages on clothing can still cause damage.
Warning: Do not attempt to remove the backplate on the rear panel of the Collage switch.
Removing the backplate exposes you to hazardous voltages that could cause injury or loss of life.

100-314-02 21
Installing
optionmodules
Guidelines for live insertion and removal
The switch supports the live insertion and removal of option modules into option slots. This means
you can insert or remove option modules without disconnecting the power cable. This is also known
as “hot swapping”.
Note: Close any open connections for ports on the option module and shut down the option module
slot before removing an option module. For information about removing an option module, see
“Removing an option module”.
When you insert an option module, the Collage switch will download code to the module to
configure it.
If your revision of software supports automatic configuration of the option module you want to install,
the option module works as soon as you have completed the installation. For more information, refer
to the Collage 700 Backbone ATM Switch User Guide (part number: 100-324).
If you replace an option module with another option module of the same type, the Collage switch
configures the replacement option module in the same state as the previously installed option
module. However, if you remove an option module then install a different type of module into the
option slot, or you install an option module into a previously unpopulated option slot, the new option
module is initialized in its default state.

Inserting an option module
Each option module has two ejector levers and a captive screw. For example, Figure 2.1 shows the
ejectors and screw for an option module.
Figure 2.1 Option module ejectors and captive screw

100-314-02 23
Installing
optionmodules
To insert an option module:
1 Using a flat-blade screwdriver, completely loosen the captive screw on the blanking plate.
2 Remove the blanking plate by pulling the left-hand side of the plate away from the switch. Keep
the blanking plate in a safe place for future use.
3 Prepare the option module by pressing the ejectors away from the centre of the module.
Figure 2.2 Pressing ejectors away from the centre of the module
4 Line up the option module with the module guides of the empty option slot and, holding the
ejectors with both hands, push the module towards the back of the unit.
Note: If the option module does not slide into the chassis smoothly, do not force it. Check that the
option module is aligned with the module guides.

5 When you are sure that the option module is fully seated in the backplane, press the ejectors on
the module towards the centre of the module. If the ejectors do not move easily, gently push the
option module towards the rear of the unit to make sure it is seated properly.
6 Using a flat-blade screwdriver, completely tighten the captive screw on the option module.

Removing an option module
To remove an option module:
1 Close all active connections for ports on the option module.
2 Shut down the option slot by connecting a management console to the switch and using the
hardware/linecard/shutdown command, or by using Collage 700 Manager.
For information about the command-line interface, refer to the Collage 700 Backbone ATM Switch
User Guide (part number: 100-324).
Note: The hardware/linecard/shutdown command shuts down the slot and closes any outstanding
connections for ports on the option module.
The port LEDs on the option module should all be off, indicating that the slot has been shut
down.
3 Disconnect the signal cables from the connectors on the option module.
4 Using a flat-blade screwdriver, completely loosen the captive screw on the option module.
5 Press the ejectors away from the option module and, holding the ejectors with both hands,
remove the module. Place the option module on an antistatic mat or foam pad, or place it in an
antistatic bag if you will be returning it to the factory.
6 Replace the blanking plate on the empty option slot (see “Replacing blanking plates”).

Replacing blanking plates
If you are installing a module into an unused option slot, remove the blanking plate and keep it in a
safe place. If you are removing a module and leaving the slot empty, always insert a blanking plate
into the empty slot and completely tighten the captive screw.
Hazard: When you remove a module or blanking plate, always replace it with another module or
blanking plate. Never operate the product when the option slots are exposed except for short periods
when you are replacing option modules.
To screw a blanking plate into an empty option slot:
1 Push the metal part on the right-hand side of the blanking plate into the space on the right-hand
side of the option slot.
2 Rest the left-hand side of the blanking plate on the mounting that houses the captive screw, on
the left-hand side of the option slot.
3 Using a flat-blade screwdriver, completely tighten the captive screw.
Replacing covers on fiber connectors
If you are installing an option module that supports fiber-optic cable, always replace the protective
covers on the connectors when you remove the signal cables.
Note: When no cable is connected to a SMF port, laser radiation may be emitted from the transmit
socket.

Chapter 3 Using the option modules
Connecting fiber cable to an SC duplex connector
When you connect fiber cables to a fiber option module, such as the Collage 753 module, make sure
you match the receive and transmit fibers to the correct sockets on the SC duplex connector.
Figure 3.1 Receive and transmit sockets on SC duplex connector
If your receive and transmit connectors are not physically joined, make sure you connect the fiber
cables correctly:
1 Insert a fiber into the right-hand socket only.
If the fiber is correct for the receive socket, the port LED turns red. If the LED does not turn
red, insert the other fiber into the socket.
2 When the port LED is red, insert the other fiber into the left-hand transmit socket.
The port LED turns amber.
Warning: Always replace the protective covers on the connectors when you remove the signal cables
from an option module that supports fiber-optic cable.
Laser radiation may be emitted from the SMF ports when no cable is connected.

100-314-02 31
Usingoption
modules
Connecting UTP cables
The Collage 744 and Collage 754 option modules provide port interfaces via RJ-45 connectors to
Category 5 UTP media.
Always use the recommended type of cable, and observe the recommended maximum cable lengths.
For more information about recommended cable lengths for an option module, see Appendix A
“Technical specifications”.
Connecting STP cables
The Collage 711 E1 and Collage 712 T1 WAN modules provide four port interfaces via RJ-45
connectors to Category 5 STP media.
Always use the recommended type of cable, and observe the recommended maximum cable lengths.
For more information about recommended cable lengths for the WAN modules, see Appendix A
“Technical specifications”.

Understanding status indicators
Each port on the option modules has a traffic status LED indicator that provides information about
the condition of the port.
The Collage 755, and Collage 756 option modules have a second laser status LED indicator.
Status indicators during start-up
During the start-up tests, the switch sets the color of the LEDs on the option modules in the chassis.
The color sequence is red, amber, then green, and the option slot sequence is Slot 1, Slot 2, Slot 3,
Slot 4, and Slot 5.
Note: If any option slot does not contain an option module, it does not take part in the start-up tests.
If the switch fails the start-up diagnostics, the Processor attempts to set the LEDs on any faulty
option modules. However, the fault may prevent the Processor from setting the LEDs on the option
module.
Table 3.1 Option module traffic status LEDs during start-up diagnostics

Meaning
red An error occurred at the physical level. Either framing was lost, cell
delineation was lost, or the remote device is not receiving and has
raised an alarm. The traffic status LED changes in real time, so you
may only see it turn red for brief periods of time.
amber The port is connected to the network, but it is not receiving or
transmitting cells.
green The port is connected to the network and is receiving or transmitting
cells. Under moderate load, the traffic status LED appears amber and
flickers green when the port receives cells. Under heavy load, the
traffic status LED is constantly green.
off No cable is connected to the port, or a cable is connected but the signal
has been lost.

Laser status indicators during normal operation
When the switch is operating, the laser status LED on the Collage 755, and Collage 756 option
modules indicates the status of the port as shown in Table 3.3.
Warning: Always replace the protective covers on the connectors when you remove the signal cables
from an option module that supports fiber-optic cable.
Laser radiation may be emitted from the SMF ports when no cable is connected.

Appendix B
Collage 740/750 power requirements, creepage, and clearance
The power specification for the Collage 740/750 power supply is 46amps at 5V and the power
requirement for the Collage 711 4-Port E1 WAN Module is 1.5amps at 5V.
The power required by the Collage 740/750 and the maximum number of installed option modules,
does not exceed the power specification of the Collage 740/750 power supply. Therefore, the switch
conforms to the approval requirements detailed below.
It is essential that, when other option modules are introduced that use or generate a hazardous
voltage, the minimum creepage and clearances specified in table B.1 are maintained. A hazardous
voltage is one that exceeds 42.4V peak a.c. or 60V d.c. If you have any doubt, seek advice from a
competent engineer before installing other adapters into the host equipment.
The equipment must be installed such that, with the exception of the connections to the host, the
clearance and creepage distances detailed in table B.1 are maintained between the card and any other
assemblies that use or generate a voltage detailed in table B.1.
The larger distance shown in brackets applies where the local environment within the host is subject
to conductive pollution, or to dry non-conductive pollution that could become conductive due to
condensation. Failure to maintain these minimum distances would invalidate the approval.
