ABOUT THIS GUIDE
This Switch 4005 Installation and Maintenance Guide provides a description of
Switch 4005 components, installation and removal procedures, site requirements,
and important safety information for Switch 4005 components.
If the information in the Switch 4005 Release Notes differs from the information in
this guide, follow the instructions in the release notes. Release notes are not
included with the product packaging. To obtain them, visit the 3Com Web site.

Audience Definition This guide is intended for network administrators who are responsible for
installing and managing the network hardware and who are considered to be
trained service personnel. This guide assumes that the network administrator has a
working knowledge of local area network (LAN) operations, but it does not
assume prior knowledge of Switch 4005 high performance networking
equipment. Furthermore, this guide assumes that the network administrator has
obtained the appropriate technical training and experience to perform tasks in
service access areas of network equipment, to be aware of electrical hazards or
other hazards that exist in performing these tasks, and to take steps that minimize
the danger to themselves or other persons.
Conventions Table 1 and Table 2 list conventions that are used throughout this guide.

1SETTING UPYOUR SWITCH 4005
To install your Switch 4005 safely and efficiently so that you can connect it to your
network, follow these tasks:
1Read Chapter 2 in this guide for a quick review of basic facts about the Switch.
2Ensure that your installation environment meets the site requirements described in
Chapter 3.
3Unpack and inspect the Switch 4005 components for visible damage, if you have
not already done so.
For unpacking procedures and information on how to proceed if damage exists,
see the Switch 4005 Key Information Guide.
See Chapter 5 for the installation procedure.
4Install the chassis.
5(Optional) Install a second power supply (for redundancy) into the chassis before
you install it on a table, shelf, or in a rack.
See Chapter 4 for the installation procedure.
3Com recommends that you do not connect the Switch 4005 to a power source
until all components are installed. This way, you can focus your attention on all
module LEDs simultaneously.
6(If required) Install Fast Ethernet and Gigabit Ethernet Interface Modules.
If you are installing a preconfigured starter kit and do not require additional
interface modules you can skip this step.
If you need to install additional modules, see Chapter 7 for the information about
their physical attributes and module installation procedure.
All chassis ship from the manufacturing center with a Switch Fabric Management
Module (SFMM) preinstalled, thus you do not have to install one. However, you
can install a second (redundant) SFMM to provide standby management support.
At your option, you may connect network cabling to your Switch 4005 interface
modules prior to powering on the Switch. However, once the Switch is powered
on, be aware that features such as the Spanning Tree Protocol’s root bridge
election process may affect your network operations. If you are unfamiliar with the
Switch 4005, 3Com recommends that you power up the Switch without cabling
attached so that you can first spend a few minutes studying the management
interface.
7Power on the system by connecting the power cables to the sockets on the Switch
4005 power supplies and then to the dedicated power outlets.
There is no ON/OFF button on the Switch 4005. The system is powered on as long
as the mains power source is connected to the Switch. If you need to cycle power

10 CHAPTER 1: SETTING UPYOUR SWITCH 4005
to the Switch 4005, you can either unplug and replug the power cord, or you can
do it through a command on the Switch 4005 management interface.
If you installed a second, redundant power supply, 3Com recommends that you
connect it to a dedicated power source.
After power is supplied to the Switch 4005, power supplies begin operating, fans
start rotating, all modules begin power-on verification processes and
self-diagnostic processes, and the SFMM begins its software boot cycle. The
module LEDs will flash in different colors and sequences during this time.
8Wait for the chassis to finish its start-up sequence of diagnostic tests.
This could take up to five minutes (approximately).
For information about module LEDs, see Table 5, Table 6, Table 11, and Table 13 in
Chapter 7.
The Switch 4005 is not ready for operation until its initialization processes finish.
This process may last up to 5 minutes.
If no problems exist at the completion of the module initialization process, you
should see the following:
■All four fans are rotating continuously.
■The AC and DC LEDs on each installed power supply are lighted.
■The Power LED on the SFMM module is Green.
■The Diagnostic LED on all modules is Green.
■The Port Link and Mode LEDs on all interface modules remain off until you
attach cabling and functioning network links are created.
If a Module Diagnostic LED is off after the diagnostics run, that module has failed.
If you observe error conditions with the following hardware components, see the
referenced chapter:
■power supplies, see “Troubleshooting a Power Supply”in Chapter 5.
■fans, see “Troubleshooting a Fan Tray”in Chapter 6.
■modules, see“Troubleshooting Modules”in Chapter 7.
9To view or modify the default software configuration, use a standard null modem
cable to connect a terminal or PC with terminal emulation software (such as
HyperTerm that is included with Windows®) to the console port on the SFMM.
At this point, the menu-driven command line interface (CLI) that is built into the
software becomes visible to you.
See the Switch 4005 Software Configuration Guide to view or modify the default
settings in the software as well as to learn about other management interface
options.
10 When you are ready to join the Switch 4005 to the rest of your network, attach
GBIC transceivers (if applicable) and network cabling to the ports on the interface
modules.
