What you get
A minimum IBM 8270 Model 600
configuration consists of an IBM 8270
Model 600 and at least one Token-Ring
Universal Feature Card, each ordered
separately. When you order an IBM 8270
Model 600, you get:
• IBM 8270 Model 600 switch (which
includes an 8270-600 processor
and power supply)
• Rack mounting brackets
• Cable management bracket
• Installation Guide and Service
Information Card
• Safety Manual
• Publications CD-ROM (which includes
softcopy of the IBM 8270 Planning,
Configuration, and Operation Guide)
• Power cord (U.S. and Canada only)
A minimum IBM 8270 Model 800
configuration consists of the following
components, each of which must be
ordered separately:
• An IBM 8270 Model 800 Chassis kit
• An IBM 8270 Model 800 Processor Card
• At least one Token-Ring Universal
Feature Card
When you order an IBM 8270 Model
800 Chassis kit, you get:
• IBM 8270 Model 800 chassis
(including an 8270-800 power supply)
• Rack mounting brackets
• Cable management bracket
• Installation Guide and Service
Information Card
• Safety Manual
• Power cord
When you order an IBM 8270 Model
800 Processor Card, you get:
• An IBM 8270 Model 800 Processor Card
• Publications CD-ROM (which includes
softcopy of the
IBM 8270 Planning,
Configuration, and Operation Guide
)
For 8270 Model 800 configurations, you
can also order an optional redundant
power supply.
Cables for each of the ports on the 8270
are required but are not included with
the switch. When operating as a Token-
Ring switch the 8270 uses the following
types of cabling:
• Category 3, 4 or 5, 100-ohm, UTP cables
with RJ-45 connectors wired to support
Token Ring
• 150-ohm, STP cables with shielded
RJ-45 connectors wired to support
Token Ring
• Any current Token-Ring lobe cabling
support for all types of connectors
• EIA-232-C cable with a DB-9 connector
for connection to the management port
• Multimode or single-mode optical fiber
with SC or ST connectors for fiber ATM
or Token-Ring ports
Model Comparison
Except for considerations pertaining
to their number of feature slots and
redundancy characteristics, the IBM
8270 Model 600 is suitable for use in
the same environments as the Model
800. However, with different redun-
dancy characteristics, the 8270 Model
600 may be better placed closer to the
edge rather than the center of your
network.
Universal Feature Cards
ATM 155 Mbps Multimode Fiber/Token-
Ring II Universal Feature Card (FC
2762, PN 86H2762)
: Switches Token-
Ring frames between the LAN seg-
ments connected to the LAN switch
and an ATM network. The ATM Multi-
mode Fiber UFC achieves this connec-
tion by providing an industry-standard
LAN emulation proxy client (LEC) that is
fully-compliant with ATM Forum
specifications. When attached to the
same ATM network, the LEC on this
UFC allows LAN traffic to be switched
between LAN stations/segments
attached to a LAN switch and other
devices with compatible ATM LAN
Emulation (LANE) implementations.
For example, traffic can be switched
between LAN stations/segments
attached to similarly equipped IBM
8270 or 8272 LAN switches across an
ATM backbone network. Furthermore,
using compatible LANE clients, traffic
can be switched between LAN
applications on Token-Ring-connected
stations and those on ATM-connected
stations. This means that traffic can be
switched between a LAN client
attached to an IBM 8270 or 8272
equipped with this ATM UFC and a file
server (for example, one equipped with
any of the IBM TURBOWAYS
®
ATM
25/100/155-Mbps Adapters) attached
directly to a connected ATM network.
The ATM Multimode Fiber UFC
provides one ATM user-network
interface/user side (UNI) and in all
cases must be connected to a compat-
ible ATM switch, such as that available
on the IBM 8265 Nways ATM Switch.
This interface complies with UNI 3.0
and 3.1 ATM Forum specifications and
operates at 155 Mbps using SONET
STS-3c framing format. Physically, this
interface is provided via an SC fiber
connector for multimode fiber media.
There are two pairs of LEDs on the
faceplate of the UFC, one indicating the
operational status of the UFC port and
one indicating the operational status of
the ATM.
