When you install the Bridge Module into the concentrator, the unit 
performs a self-test to verify proper operation of the internal hardware and 
communication interfaces.  To test the unit independently of network 
activity, follow these steps prior to plugging the module into the 
concentrator:

1. Install the provided Ethernet loopback connector to the AUI port on 

the module as shown in Figure 2-3.

2. Remove two adjacent blank concentrator panels to expose two slots 

for the Bridge Module.

3. Insert the module into the board guides at the top and bottom of the 

slots and slide it into the concentrator.  Make sure the connectors are 
well seated into the backplane of the concentrator.
