2 - 10 ONline Ethernet Bridge Module Installation and Operation Guide
Pre-Installation Test
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.
