Installation Summary
Catalyst 3920 Token Ring Switch User Guide
3-2
Dedicated Media
For installations where permanently installed building cable is available, 100-ohm UTP Category 3,
4, or 5 can be used. IBM Cabling System 150-ohm, STP cables (types 1 and 9) can also be used.
Because the RJ-45 connectors on the Catalyst 3920 use pins 3, 4, 5, and 6, a cable with an IBM STP
data connector on one end and an RJ-45 connector on the other must be constructed.
Shared Media
The types of cables that can be used are the same as those described above for dedicated-media
segments. The acceptable distances are defined by the hub or concentrator attached to the
Catalyst 3920 port.
