CHAPTER 4: Installation
NOTE
a) Because the Fiber Optic
Converter I has only one
RJ-45 connector (it uses
only Channel 1), the setting
of Switch 2 can be
disregarded.
b) When converters are used
in the main ring, Switches 3
and 4 should always be in
the up position (open).
Refer to Figure 4-3 for switch setting
information. Configure the RJ-45
connector as Ring In if it connects
to Ring Out of a MAU, and vice
versa. See Figure 4-2 for an example.
(More information on the Config
switch is given in Chapter 3.)

2.
Plug the power cords into the
backs of all Converters and into
electrical outlets.
3.
Connect the fiberoptic cables to
the appropriate connectors on
the Converters. TX on a
converter must connect to RX
on its mate. Two optical fibers
are required between each pair
of the Fiber Optic Converter I;
four optical fibers are required
between each pair of the Fiber
Optic Converter II.
4.If the network is not activated,
connect the RJ-45 pins on the
converters to the appropriate
Ring In and Ring Out
connectors on the MAUs. (Ring
In receives the cable from the
previous MAU or Converter;
Ring Out connects to the cable
going to the next MAU or
converter.)
Bring up the network and make
sure it is operating properly.
