New model
A new member has been added to the
IBM 8270 Nways
®
LAN Switch family of
Token-Ring LAN switches. The new
Model 600 joins the Model 800, providing
a smaller, entry configuration (six slots).
Both models allow flexible configuration
with rich functionality provided by the
com mon set of Universal Feature Cards
they share. Similar to the Model 800, a
typical net work would benefit from the
Model 600 by having each of its high-
volume servers placed on dedicated
full-duplex segments and having client
workstations placed on shared seg-
ments using standard Token-Ring
concentrators such as the IBM 82 39
Token-Ring Hub.
New features
Two new UFCs extend MSS forwarding
and routing services to the 8270 Nways
LAN S witch Family. Both the MSS Client
and MSS Domain Client Universal
Feature Cards (UFCs) provide for ward-
ing and routing services. The MSS Client
also has an integrated ATM port and
provides ATM-to-LAN port bridging.
These client-function products co mplete
the MSS client/server family and allow
the MSS Server products to per for m their
job in the net work at ma ximum efficiency.
Along with virtual LAN (VLAN) support by
proto col, OSI Layer 2 and 3 for warding of
IP, IPX, AppleTalk and Banyan VINES
proto cols are provided.
Cost-effective Token-Ring
switching
The IBM 8270 Nways To ken-Ring L AN
Switch provides a cost-effective solution
to Token-Ring LAN per formance
requirements. With a minimum of
disruption to existing net works, you can
significantly address L AN per for mance.
A power ful LAN switch
With the 8270 you can build large
switched networks with high-speed
uplinks. A redundant power supply is
available to help ensure continuous
operation.
You can configure the versatile, modular
8270 LAN switch to:
• Add from 4 to 30 por ts to your net work
configuration, more ports per switch than
any other model.
• Install uplink UFCs to connect native
proto cols to high-speed links like high-
speed Token Ring, ATM or the IBM 8260
Nways Multiprotocol Switching Hub.
