xvi 25 Mbps ATM Module - Installation and User's Guide
Chapter 1. Overview
This chapter presents an overview of the ONcore 12-Port 25 Mbps ATM I/O Module
(6412M-25-TP). It describes the main functions of the module, and how the module
operates as part of the ATM subsystem when installed in the ONcore Integrated System
Hub or CELLplex 4000 Expansion Unit.
6412M-25-TP Module Features
The 6412M-25-TP module is a single-slot module that functions as part of the ONcore
ATM or CELLplex 4000 Expansion Unit.
Chapter 1. Overview 1-1
6412M-25-TP modules can be used in any of the following ways:
To send and receive data from an ATM subsystem in another ONcore ATM
switching hub or CELLplex 4000.
To attach high capacity workstations and servers (with 25.6Mbps adapter cards)
that function in ATM mode.
6412M-25-TP modules interface to the ONcore hub or CELLplex 4000 by means of the
Control Point located in either the ONcore ATM Switch/Control module or CELLplex
4000 base unit. 6412M-25-TP modules process ATM cells of data by:
Checking their validity
Accessing the switching tables to locate the destination module
Preparing the internal ATM format required by the Control Point
Sending the cells to the Control Point
6412M-25-TP modules can be used in any vacant slot in the CELLplex 4000 expansion
unit, or any vacant slot in the ONcore hub except for slots 9, 10, and (for 17-slot
models) 11 and 12. These slots are reserved for ONcore ATM Switch/Control modules.
In 17-slot ONcore models, although slot 12 is also reserved, you can insert an
6412M-25-TP module in slot 12 if no ONcore ATM Switch/Control module is installed in
slot 11.
Like other ATM media modules, the 6412M-25-TP module can be inserted while the
hub or CELLplex 4000 is operating without disturbing data traffic on other modules.
Before removing the module however, you must first isolate it by using the SET
MODULE command.
For more information on how to install and change modules, see the
System Hub Installation Guide
Installation and User's Guide
, Document Number 17-000362 or
Document Number 17-000865, as appropriate.

Module Functions
The 6412M-25-TP module has the following characteristics:
Twelve ports operating at up to 25 Mbps to connect stations or servers to the hub
or CELLplex 4000. Each port may connect to:
– An ATM or multimedia workstation that requires a high bit rate (UNI connection)
– A UNI device using a supported interface
Physical interface: copper cable with RJ45 connector.
ONcore 12-Port 25 Mbps ATM I/O Module connections: port-to-port, hub-to-server,
and hub-to-workstation.
Up to three 6412M-25-TP modules can be used in the CELLplex 4000 expansion
unit, thereby providing up to 48 ATM ports.
Up to fourteen 6412M-25-TP modules can be used in the 17-slot ONcore hub at the
same time (8 in the 10-slot ONcore hub).
Interfaces Supported
The 6412M-25-TP module supports the following interfaces:
User-to-network (UNI)
Network-to-network (NNI)
Switch-to-switch (SSI)
The UNI interface is defined in the following documents:
ATM Forum UNI Specification V3.0 and V3.1
ITU (ex-CCITT) SG13 as defined in the following standards:
– I.413 (B_ISDN User-Network Interface)
– I.432 (Physical Layer)
– Q.2931 (Signaling)
Chapter 1. Overview 1-3
Using the 6412M-25-TP Module for ATM Campus
Networking
The 6412M-25-TP module can be used as a link to an ATM campus network by
allowing workstations, servers, and other ATM devices to communicate with the
network.

Chapter 2. Installation
This chapter describes how to unpack, install, and connect ATM devices to the
6412M-25-TP module.
Before You Unpack the Module
Take the following precautions before unpacking the 6412M-25-TP module:
Do not remove the 6412M-25-TP module from its anti-static shielding bag until you
are ready to install it. This avoids the possibility of having electrostatic discharge
damage static-sensitive devices on the module.
Always handle the module by the edges.
Always use a foot strap and grounded mat or wear a grounded static discharge
wrist strap whenever you inspect or install or remove the module. Or else, be sure
to touch a grounded rack or another source of ground before handling it.
Chapter 2. Installation 2-1
Unpacking the Module
To unpack the 6412M-25-TP module, follow these steps:
1. Verify that the 6412M-25-TP module is the correct model by matching the model
number listed on the side of the shipping carton to the model number you ordered.
Note: The product model number printed on the shipping box differs from the
model number on the product. The model number on the shipping box bears the
prefix 3C9.
2. Remove the module from its shipping carton.
3. Remove the 6412M-25-TP module from its anti-static bags and inspect it for
damage. Always handle it by the edges, being careful not to touch the internal
components.
If the module appears to be damaged, put it back in the anti-static bag, put the bag
back into the shipping carton, then contact your local 3Com dealer.
It is recommended that you retain the shipping carton and the anti-static shielding bag
in which the module was delivered. These can be reused later if you want to repackage
the components for storage or shipment.

Installation Summary
Note: The installation activities described in the following sections should be
undertaken by TRAINED SERVICE PERSONNEL ONLY.
Table 2-1 lists the steps to follow to install the 6412M-25-TP module. Each step is
described in detail in this chapter.
Note: Before installing an 6412M-25-TP module in an ONcore switching hub, make
sure that an ONcore ATM Switch/Control module is installed in slots 9 and 10 (or 11
and 12 in a 17 slot model), and that an ONcore ATM Switch/Control console has
already been configured. If an ONcore ATM Switch/Control module is not installed, the
Reset LED on the 6412M-25-TP module will start blinking when you insert the module.
Table 2-1. Installation Steps
Step Refer to
1. Insert the 6412M-25-TP module into a vacant slot:
ONcore: 1 to 8 on 10-slot models (or 1 to 8, 12 to
17 on 17-slot models).
CELLplex 4000: Any vacant slot in the expansion unit.
2. Set up connections between the ONcore 12-Port 25
Mbps ATM I/O Module ports and other ATM devices using
the appropriate Twisted Pair (TP) cables and connectors.
