Token-Ring Ports
Twisted-Pair Cable Pin-Outs
When connecting devices to the token-ring ports on the switch, you must use a
straight-through cable. Diagrams of these cables follow.
Straight-Through 100-Ohm/120-Ohm Cable
The switch RJ-45 connector makes ground available on the shield and on pins 1, 2,
7, and 8. Shielded cables will provide continuity for ground to any shielded
connector on the other end of the cable.
