4. If the LEDs are not lit, reverse the cable ends back to their original 

positions, and contact Cabletron Systems Technical Support for 
assistance.

Before installing the FOMIM in a live network, test the module in a 
controlled situation to ensure that it is repeating packets. With the 
FOMIM installed in an MMAC hub with a Repeater module (e.g., IRM3), 
this test can be performed with two workstations (Figure 3-1) by 
completing the following steps:

1. Install the FOMIM into an MMAC chassis with an IRM3.

2. Connect the first workstation to the IRM3 using either the AUI port, 

(with a transceiver and an AUI cable), or to the fiber optic port, (with 
fiber optic cable), depending on which is the active repeater port.

3. Connect the second workstation to the FOMIM, using the appropriate 

transceivers and cable.

4. Set the first workstation as the file server and the second as the client 

(refer to the workstation documentation for setting up the workstations 
as file server and client). When the workstations are properly set up, 
proceed to send packets between the workstations and verify that the 
FOMIM is operating properly. 

The IRM3 must be installed in slot one of the MMAC chassis.

The AUI port is the default active repeater port on the IRM3. If 
you want to test the module using the fiber port, it must be 
selected through Local Management. Refer to the Local 
Management section of the IRM3 User’s Guide for more 
information on selecting the active repeater port.
