Cards
IBM 8270 Nways Token-Ring Switch
Model 600
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
common set of Universal Feature Cards
they share. Similar to the Model 800, a
typical network 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 8239
Token-Ring Hub.
New features
Two new UFCs extend MSS forwarding
and routing services to the 8270 Nways
LAN Switch Family. Both the MSS Client
IBM 8270 Nways Token-Ring Switch
Model 800
and MSS Domain Client Universal
Feature Cards (UFCs) provide forward-
ing and routing services. The MSS Client
also has an integrated ATM port and
provides ATM-to-LAN port bridging.
These client-function products complete
the MSS client/server family and allow
the MSS Server products to perform their
job in the network at maximum efficiency.
Along with virtual LAN (VLAN) support by
protocol, OSI Layer 2 and 3 forwarding of
IP , IPX, AppleTalk and Banyan VINES
protocols are provided.
Cost-effective Token-Ring
switching
The IBM 8270 Nways Token-Ring LAN
Switch provides a cost-effective solution
to Token-Ring LAN performance
requirements. With a minimum of
disruption to existing networks, you can
significantly address LAN performance.
A powerful 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 ports to your network
configuration, more ports per switch than
any other model.
• Install uplink UFCs to connect native
protocols to high-speed links like high-
speed Token Ring, ATM or the IBM 8260
Nways Multiprotocol Switching Hub.
