3Com 6412M-25-TP manual Set, Mbps ATM Module Installation and Users Guide

Page 18

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.
