ABOUT THIS GUIDE
This guide provides all the information you need to install and use the
IBM 8271 Nways Ethernet LAN Switch Models F12 and F24 with
default settings. If you want to change the way the Switch works using
management software, refer to the “IBM 8271 Ethernet LAN Switch
Management Guide” (part number 35L2186).
This guide is intended for use by network administrators who are
responsible for installing and setting up network equipment. It assumes
a basic working knowledge of LANs (Local Area Networks).
This guide is intended for use with both F12 and F24 models:
■02L0878 — 12 10BASE-T/100BASE-TX ports
■02L0879 — 24 10BASE-T/100BASE-TX ports
All pictures and example screens show the 24-port model, however, all
procedures also apply to the 12-port model.
If the information in the Release Notes shipped with your product
differs from the information in this guide, follow the Release Notes.

1INTRODUCING THE SWITCH
This chapter contains introductory information about the Switch and how
it can be used in your network. It covers the following topics:
■About the Switch
■Switch — Front View Detail
■Switch — Rear View Detail
■Network Configuration Examples
■Configuration Rules for Fast Ethernet
■Configuration Rules with Full Duplex
F24usr.bk Page 17 Thursday, January 14,1999 10:41 AM

18 CHAPTER 1: INTRODUCING THE SWITCH
About the Switch The Switch F12/F24 connects your existing 10 Mbps devices, connects
high-performance workgroups with a 100 Mbps backbone or server
connection, and connects power users to dedicated 100 Mbps ports —
all in one switch.
As part of the 8271 range, the Switch Models F12 and F24 meet the
challenge of modern LANs and allow you to add features and expand
capacity as your network grows.
Summary of Features The Switch has the following hardware features:
■12 or 24 Fast Ethernet auto-negotiating 10BASE-T/100BASE-TX ports
■Matrix port for interconnecting Switch F12 and F24 / Switch E12 and
E24 units in a single stack:
■Connect two units back-to-back using a single Matrix Cable
■Connect up to four units using Matrix Cables linked to a Matrix
Module
■Slot for an Expansion Module or Matrix Module
■Connects to Redundant Power System / Uninterruptable Power
System
■19-inch rack or stand-alone mounting
For information about the software features of the Switch, refer to the
“IBM 8271 Nways Ethernet LAN Switch Management Guide” (part
number 35L2186).

10BASE-T/
100BASE-TX Ports
The Switch has 12 or 24 auto-negotiating 10BASE-T/100BASE-TX ports
configured as MDIX (cross-over). These ports can be set to 10BASE-T half
duplex, 10BASE-T full duplex, 100BASE-TX half duplex, 100BASE-TX full
duplex, or they can automatically detect the speed and duplex mode of a
link and provide the appropriate connection. The maximum segment
length is 100m (328ft) over Category 5 twisted pair cable.
As these ports are configured as MDIX (cross-over), you need to use a
cross-over cable to connect to devices whose ports are MDIX-only. See
“Choosing the Correct Cables” on page 36 for more information.
LEDs Table 1 (overleaf) lists the LEDs visible on the front of the Switch, and
their states according to color. For information on using the LEDs for
problem solving, see “Solving Problems Indicated by LEDs” on page 37.

Ta b l e 1 LED behavior
LED Color Indicates
Port Status LEDs*
* If your Switch has 24 10BASE-T/100BASE-TX ports, these ports are numbered 1 to 24. If your
Switch has 12 10BASE-T/100BASE-TX ports, these ports are numbered 1 to 12. For both
models, ports supplied through an Expansion Module are numbered sequentially from the last
fixed port on the front of the unit.
Packet Yellow Packets are being transmitted/received on the port.
Off No packets are being transmitted/received on the
port.
Status Green A link is present, and the port is enabled.
Green flashing A link is present, but the port is disabled.
Off No link is present.
Expansion Module Port Status LEDs
Packet Yellow Packets are being transmitted/received on the
Expansion Module port(s).
Off No packets are being transmitted/received on the
Expansion Module port(s).
Status Yellow A valid Expansion Module is installed in the Switch.
Yellow flashing An unrecognized Expansion Module is installed in
the Switch.
Off No Expansion Module is installed in the Switch.
Unit LEDs
1–8 Green The Switch forms a stack with other Switch F12
and F24 / Switch E12 and E24 units; the LED
indicates the position of the Switch in the stack
and that a link is present. Note that although there
are eight LEDs, only four Switch units can be
stacked at present.
Off The Switch is stand-alone.
Power/Self Test LED
Green The Switch is powered-up.
Green flashing The Switch is either downloading software or is
initializing (which includes running a Power On Self
Test).
Yellow The Switch has failed its Power On Self Test.
Off The Switch is not receiving power.
