INSTALLATION

Using the 5-Segment Rule (10BASE-T)
The Ethernet 10BASE-T 5-segment rule defines a segment as the cable
connection between station interfaces. The transmission path between
any two terminal devices in the same collision domain can consist of
no more than five segments. Installing the TRANSITION Networks’
bridging media converter in the network separates collision domains,
so the 10BASE-T 5-segment rule applies separately to each collision
domain.
To assign segment numbers to cable connections:
1. Determine the network device separated from the Transition
Networks’ pocket switch by the greatest number of segments.
2. Define a segment path between that network device and the
Transition Networks’ pocket switch by labeling the cable
connection to the Transition Networks’ pocket switch “segment
1” and numbering each segment in the path to the terminal up to
“segment n” (n = total number of segments
†
5).
3. Verify that no segment path in the collision domain contains
more than n
†
5 segments.
4. Repeat steps 1-3 for next collision domain.
OPERATION
Use the status indicator LEDs to monitor E-PSW-FX-03 operation in
