About This Manual
This manual explains how to install and service the IBM 8270 Nways Token-Ring
LAN Switch Models 600 and 800 (hereafter referred to as 8270-600 and 8270-800 ).
8270 refers to both 8270-600 and 8270-800.
The 8270 comes preconfigured for Plug and Play capability. You might not have to
configure the switch for it to operate in your network. However, should you choose
to change default settings, refer to Planning, Configuration, and Operation , which is
on the 8270 Switch User's Guide CD-ROM.

¹Chapter 1, “Physical Characteristics and Features” describes the 8270. It also
provides a brief functional overview.
¹Chapter 2, “Installation” describes installation and cabling procedures.
¹Chapter 3, “Setting up a Console Session” describes how to set up a local or
remote console.
¹Chapter 4, “Updating Software” describes procedures for downloading new
code.
¹Chapter 5, “Troubleshooting and Service” provides troubleshooting procedures
and how to get help from IBM.
¹Chapter 6, “Service Procedures for Qualified Personnel” describes the parts

Chapter 1. Physical Characteristics and Features
The IBM 8270 Nways Token-Ring LAN Switch is a member of and fully compatible
with the 8270 family of LAN switches, which includes the 8272 Nways Token-Ring
LAN Switch, Models 108 and 216, and the 8272 LAN Switch Modules, Feature
Codes 5208, 5308, 6208 and 6308, for the IBM 8260 Nways Multiprotocol
Switching Hub and 8265 Nways ATM Switch.
The 8270 provides high-speed forwarding of Token-Ring frames among the shared
or dedicated Token-Ring segments attached to each of the 8270 ports. The 8270
creates multiple, concurrent paths among the connected segments, each supporting
the full, 16-Mbps Token-Ring bandwidth. The 8270 also supports ATM uplink
connections.
The 8270 forwards Token-Ring frames among multiple, shared or dedicated,
Token-Ring LAN segments. Using a frame-forwarding technique similar to that of a
multiport, Token-Ring transparent bridge, the 8270 uses both Token-Ring MAC
addresses and source-route descriptors to forward Token-Ring frames from one of
its ports to another.
Figure 1-1. The IBM 8270 Nways Token-Ring LAN Switch Model 800 and 600
The 8270 is a rack- or surface-mount chassis that provides slots for one
Token-Ring Processor Card and up to six (for the 8270-600) or eight (for the
 Copyright IBM Corp. 1998 1-1

8270-800) Universal Feature Cards (UFCs). In addition to supporting more UFCs,
the 8270-800 can have redundant, load-sharing power supplies and redundant
cooling fans. The 8270 can connect to Token-Ring and ATM networks. All LAN
ports on the 8270 are provided by UFCs. At least one UFC must be installed in
order to have a functional unit. The following UFCs can be installed in the 8270:
¹4-Port Token-Ring/Enhanced UTP/STP UFC
¹2-Port Token-Ring/Enhanced Fiber UFC
¹ATM 155-Mbps Multimode Fiber/Token-Ring II UFC
¹MSS Client Single Mode Fiber UFC
¹MSS Client Multimode Fiber UFC
¹MSS Domain Client UFC
Physical Characteristics
The 8270 consists of a base unit, a Token-Ring Processor Card, and at least one
Universal Feature Card (UFC). The 8270-800 can have either one or two power
supplies.
The front views of the 8270-600 and 8270-800 are illustrated in Figure 1-2 and
Figure 1-3 on page 1-3 respectively. Following the illustrations is a description of
each of the plug-in modules and UFCs. The connectors, indicators, and switches
for each module are also discussed.

Power Supply The 8270-600 has a single internal power supply, while the 8270-800 provides the
capability to have two power supplies. Both the 8270-600 and the 8270-800 can
operate on input line voltage from 100—240 volts.
8270-800 Power Supply: The 8270-800 provides two slots for power supplies.
These are the two leftmost slots in the chassis. (see Figure 1-3). At least one
power supply must be installed. The 8270-800 is shipped with a single power
supply installed in the right slot. The left slot is available for installation of an
optional, redundant power supply.
If two power supplies are installed, they share the power load. In the event of a
failure by either supply, the good power supply automatically maintains power for
the entire 8270-800. Operation of the 8270-800 is not disrupted.
The 8270-800 power supplies are hot-pluggable That means they can be removed
and installed while the 8270-800 is powered up. When two power supplies are
installed, hot-plugging allows a failed power supply to be replaced without
disrupting operation of the switch. Both power supplies must have a line cord
connected to ac power.
Figure 1-4 on page 1-4 illustrates the 8270-800 power supply.
