CrossFire 8600/8605 Token-Ring Switches v. 1.2, P/N: 710001641 Overview and Specifications
Token-Ring Ports
•
CrossFire 8600
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.
•
CrossFire 8605
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.

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 level of capability possible. 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 twenty Token-Ring ports can be configured as a TokenProbe port. It is
used to monitor any one of the other Token-Ring ports so that the activity can be
traced by a special passive network analyzer attached to the TokenProbe port.
