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

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.
