Introduction

 

The Cabletron Systems Fiber Optic Media Interface Modules are 
designed to be installed into the Cabletron Systems Multi Media Access 
Center (MMAC). The modular design of the MMAC allows the FOMIM 
to co-exist with other Media Interface Modules (MIMs) to provide a 
variety of different media connections on any one point.

Each packet entering the FOMIM is repeated by the repeater module in 
the MMAC. Each packet that enters the repeater module is regenerated 
and retimed, which assures data integrity and maximum data path 
distance. In addition, the repeater feature ensures fault isolation, because 
the repeater module automatically segments problem ports from the 
network. A segmented port automatically reconnects to the network once 
the port receives a good packet.

The repeater module also allows you to access the network management 
capabilities that enable you to control the FOMIM and its attached 
segments. For example, information on the number of good packets and 
collisions that have passed through the FOMIM and each port on the 
MIM can be gathered. For more information on managing the FOMIM, 
refer to your specific management module Local Management Guide.

 

The FOMIM uses Cabletron Systems built-in visual diagnostic and status 
monitoring system, LANVIEW. Using LANVIEW, network 
troubleshooting personnel can quickly scan the LANVIEW LEDs to 
observe network status, diagnose network problems, and determine which 
node or segment is faulty (see Figure 1-2).
