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
Download from Www.Somanuals.com. All Manuals Search And Download.
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 ONcore Integrated
System Hub Installation Guide, Document Number 17-000362 or CELLplex 4000
Installation and User's Guide Document Number 17-000865, as appropriate.

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.

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.

Connecting ATM Devices
After inserting the module, attach the cables to the ATM ports that will connect to ATM
devices.
Cabling Up
The following sections provide instructions and guidelines for connecting ATM devices
(such as switches, servers, personal computers, and workstations). Remember these
tips when connecting cables:
Avoid stretching and bending the cables too much.
Avoid routing the cables near potential sources of electromagnetic interference,
such as motorized devices and fluorescent lights.
Avoid trip hazards by routing the cables away from aisles and other areas where
people walk. If such routes cannot be avoided, use floor cable covers or similar
material to secure and protect the cables.
Be sure that the cables connected to the 6412M-25-TP module are supported so
that the cable connectors are not excessively strained. The cable management
bracket shipped with the ONcore hub or CELLplex 4000 expansion unit helps
prevent strain on the cables.
Use a Category 3 or better UTP cable or a 150-ohm STP cable for each of the ATM
ports.

Look at the cabling chart, which your network planner provided, to determine
how the ONcore switching hub or CELLplex 4000 should be connected to the
network.
In the work area, connect one end of a straight-through cable (with
ATM-compliant pin assigments) to the ATM connector on the device and the
other end to the ATM connector on the faceplate where the building wiring
terminates.
3

5
Label the faceplate if it does not already have a cable label. Follow your
enterprise’s procedures for cable labeling. If there is more than one wiring
closet on a floor, record on the same line, the wiring closet identifier or
location and the cable identifier.
In the wiring closet, connect the cable that originated at the ATM device to
the appropriate connector on the patch panel or other equipment where the
building wiring terminates. Connect the other end of the cable to an ATM
port on the 6412M-25-TP module.
Label the connector on the patch panel (or other equipment used to
terminate the building wiring).

Chapter 3. Configuration
After installing the 6412M-25-TP module and attaching media cables to ATM devices,
you must enter configuration commands from the ATM console to:
Configure the ports parameters.
Connect the module to the network.
Enable the ports.
This section describes the ATM commands you need to enter to configure each
6412M-25-TP module in the ways described above. For a complete description of all
ATM commands, see the ONcore ATM Switch and CELLplex 4000 ATM Command
Reference Guide (hereafter referred to simply as the Command Reference Guide).
Configuring Port Parameters
The 6412M-25-TP module uses the user-to-network (UNI) interface. A UNI interface
defines the interface between an ATM user device (such as a router, bridge, server,
workstation, or concentrator equipped with an ATM adapter) and the ATM network.
Before you connect a 6412M-25-TP module to the ATM network (as described in
“Connecting the Module to the Network” on page 3-6) and enable its ports, you must
first set the type of ATM interface used on each port (UNI).
In addition, you can switch ILMI flow control on or off, and specify the ILMI
characteristics.
When a port is enabled, it can transmit and receive cells in the ATM network. The port's
parameters should be configured before the port is enabled.
