CrossFire 8600/8605 Token-Ring Switches v. 1.2, P/N: 710001641 Switch Theory of Operation
Expansion Module Slots
Feature Function Benefit
Four-port RJ-45
UTP/STP
Gives the switch an
additional 4 or 8
Token-Ring UTP/
STP ports.
Enables gradual expansion of
switch capacity.
Four-port fiber
(ST)
Gives the switch an
additional 4 or 8
Token-Ring Fiber
ports.
Enables installation in existing
fiber RI/RO connections and
fiber cabling environments (up
to 2 km).
ATM155 uplink
Gives the switch
access to 1 or 2
ATM155 uplink
connection(s) with
LAN Emulation.
Enables smooth migration to
ATM backbone networks and
enables redundant ATM
uplinks to be established.
Allows VLANs to be
multiplexed between switches
using ATM.
High-Speed Token-
Ring (HSTR)
Gives the switch
additional 2 or 4
HSTR ports.
HSTR allows Token-Ring
operation at 100 Mbps and
offers thus a 625 %
performance improvement
over “classic” 16 Mbps
Token-Ring.
HSTR is by far the most cost-
effective and non-disruptive
method for performance
upgrade of one existing
Token-Ring LAN.
