3270 REPEATER-FIBER/3270 REPEATER-UTP
Before installation, check to make
sure your Repeater was not damaged
during shipping. If there is any
damage, call your supplier.
When you install your Repeater, shut
off your workstation, controller, and
all other devices before you begin.
Place the Repeater on a flat, dry,
stable site with enough clearance
for all connections. It should be
installed within 6 feet (1.8 m) of
an AC outlet.
3.1 Pre-Installation Check
Check the following before installing
your repeater:
• Your cable must not have any
bridge taps. The wires of the
twisted pairs must not be
separated. Avoid using flat silver
satin cable, as this type of cable
is highly susceptible to external
interference, and may create
problems.
If you are using multipair cable,
avoid connecting multiple
services under the same sheath.
Use bulk cable 100 feet (30.5 m)
or longer.
• Verify that the wiring polarity
is straight-through between the
host and the workstations.

3.2 Installing the 3270 Repeater-
Fiber
Follow these steps to install the
3270 Repeater-Fiber:
• Some brands of controllers
and terminals may require
DC-continuity between the host
and the workstation. The 3270
Repeaters have DC isolation and
might not work with this type
of equipment. Check with
your computer dealer for
more information.
• Avoid nearby sources of
electromagnetic interference
such as motors, transformers,
and fluorescent lighting.
1.The 3270 Repeater-Fiber is
designed to operate in pairs.
One Repeater is installed at the
host side; the second is installed
at the station side. To protect
the connectors, do not remove
the fiberoptic covers until you
are ready to make the fiber
connections.
2.Connect the twisted-pair
segments as explained in
Steps 1-10 in Section 3.3.
Make sure that straight-through
polarity is maintained.
