2.4.1 Connecting the AUI Interface

The FN10 includes one Ethernet Attachment Unit Interface (AUI)
connector (Port 1). To connect the AUI to a thick coax network, you must
use an AUI drop cable and a tap-type transceiver:

1. Attach a tap-type transceiver to the thick coax cable. Refer to the

transceiver manufacturer’s documentation for installation
instructions.

2. Connect one end of the AUI drop cable to the FN10’s AUI port and the

other end to the tap-type transceiver.

To connect the AUI to an alternate media, such as thin coax, you must use
a transceiver connected to the AUI port. Be sure that the transceiver
matches the type of Ethernet cable you are using.

2.5 ADDING OR REPLACING THE OPTIONAL FAST

ETHERNET MODULE

The FN10 is available with an optional Fast Ethernet module to add two
additional ports that can be configured for either 10 or 100 Mbps. If you
have purchased a FN10/FE, the Fast Ethernet (FE) module is already
installed in your FN10.

If you have purchased the FE module separately, or you need to replace an
existing FE module, follow the steps below:

1. Disconnect the FN10 from the network and remove the power cord

from the rear.

2. Loosen the 2 spring-loaded fastening screws securing the blank

backplate and remove the backplate from the FN10. Refer to
Figure 2-5.

NOTE

The Ethernet Attachment Unit Interface (AUI) Port and Port 1
on the FN10’s front panel cannot be used simultaneously. If
you connect an RJ45 cable to Port 1 and an AUI cable to the
AUI Port, the FN10 automatically uses the RJ45 connection, as
long as there is a good link. If there is no link on Port 1, or the
link goes down, the FN10 automatically switches to the AUI
Port until there is a good link on Port 1.
