LACEMENT
The Fiber Optic Converter may be
either rack-mounted or placed on
a shelf or table. An optional rack-
mount kit (model RM-S00) is
available which allows installation
in a standard 19” equipment rack.
4.2 Installation in the Main Ring
Once the network has been fully
planned, all devices have been
placed and the proper cabling has
been routed to all areas where it will
be needed, use the following
procedure to finish the installation.
(If you are using Converters to
extend an individual lobe, don’t
use this section. See Chapter 4.)

Configure each Converter’s
RJ-45 connectors for their
intended use with the Config
Switch, located on a convertor’s
front panel. A Fiber Optic
Converter II has two RJ-45
connectors; a Fiber Optic
Converter I has one. Figure 4-2
shows a sample application and
tells how the RJ-45 connectors
must be configured.
