Token Ring Ports

•
STS16-20RM
Twenty shielded RJ-45 connectors for Token Ring connection.
— Support for the IBM Cabling System via 150 ohm, shielded twisted-pair
(150 ohm STP); or 100 or 120 ohm unshielded twisted-pair via Category
3, 4, or 5 cables.
— These ports allow half-duplex (HDX) or full-duplex (FDX) connections to
other switches, hubs, or end nodes.
— Ports 19 and 20 can attac to a MAU/CAU RI/RO port
•
STS16-20FRM
Twenty fiber VF-45 connectors for Token Ring connection.
— These ports allow half-duplex (HDX) or full-duplex (FDX) connections to
other switches, hubs, or end nodes.
— All 20 fiber ports can attach to a MAU/CAU RI/RO port.
— On STS16-20FRM, UTP/STP connections are only available by installing
an SSIM-T5-04 Token-Ring SmartStack Interface Module.

The switch will automatically sense what type of Token Ring connection is
being employed on each of its ports, whether it is a connection:
— to a shared-media segment via a Token Ring concentrator (Station mode)
— to another Token Ring switch
— operating at 4 Mbps or at 16 Mbps
— to a dedicated-media segment, directly to a Token Ring LAN station
operating in half-duplex or full-duplex mode (Port mode)
The switch will automatically configure (requiring no operator action) each port to
operate at the highest possible level of capability. No special crossover cables are
required for Token Ring stations on dedicated-media segments or for switch-to-
switch connections; the same straight-through cabling is used regardless of the type
of connection. This auto-sense/auto-configure capability of the switch can be
overridden by explicit console management.

Switched Port Analyzer

Any of the Token Ring ports can be configured as an analyzer port. An analyzer
port is used to monitor any of the other ports in the same physical switch. The
activity can then be traced by a Token-Ring network analyzer attached to the
analyzer port.
