Install Repeaters in Parallel
When you install repeaters in parallel, you can install a maximum
of 48 repeaters (the maximum number of taps per 250m segment)
on any one segment.
If your link is configured using repeaters in parallel, you count one of
the repeater taps for one segment and the other repeater tap for the
parallel segment that the repeater is connecting to the backbone
network.
Refer to the Installation Instructions that shipped with your repeater
for an example parallel toplogy drawing.
Install Repeaters in a Combination of Series and Parallel
You can install repeaters in a combination of series and parallel
connections to form a link. Follow the guidelines listed for each type.
For mixed topologies (series and parallel), you can verify the
maximum number of repeaters and media by using RSNetWorx.
Refer to the Installation Instructions that shipped with your repeater
for an example combination series/parallel toplogy drawing.
TIP
If your network is configured using repeaters in
combination of series and parallel, you need to
count the taps and repeaters in all segments.
