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.

2OVERVIEW OF THE SWITCH 4005
This chapter provides an introduction to the design of the 3Com®Switch 4005.
The topics in this chapter include:
■Product Overview
■Switch Backplane Architecture
Product Overview The Switch 4005 is a feature-rich, 14-slot, modular routing switch that can be
configured with up to 24 Gigabit Ethernet ports or up to 96 Fast Ethernet ports
with currently available modules. The Switch 4005 currently supports redundant
power supplies, redundant Switch Fabric Management Modules, and a variety of
Fast Ethernet and Gigabit Ethernet Interface Modules. Combining the speed and
low
cost of a Layer 2 switch with Layer 3 routing capabilities, the Switch 4005
currently
routes the IP protocol and offers many other advanced features to
provide the high performance that you need to aggregate wiring closets in your
network.
Physical Description A Switch 4005 chassis can contain:
■Two fan trays.
Each fan tray contains two fans (four fans total). Both fan trays are required for
normal operation.
■Two 300 Watt AC power supplies
Only one power supply is required for normal operation. If installed, a second
power supply provides load-sharing and redundancy.
■Two Switch Fabric Management Modules (SFMMs)
Only one SFMM is required for normal operation. If the SFMM is removed from
a powered up chassis that is functioning in a network, chassis operations will
cease. However, if a backup SFMM is installed in the chassis, and the primary
SFMM is removed or fails, the backup SFMM will take over operations.
The SFMM has two elements: a central switch fabric, which manages the
layer 3 routing functions of the system such as routing table updates and
layer 3 configuration changes, and the management of the system, which
includes SNMP, command line interface (CLI), and Web client activities.
■Up to Twelve Fast Ethernet or Gigabit Ethernet Interface Modules
You install the number and type of interface modules that are appropriate to
your cabling infrastructure and bandwidth requirements. When the source and
destination ports are located on the same interface module, the interface
module performs local switching. If the destination port resides on a different
interface module, the interface module forwards the packet to the SFMM.

12 CHAPTER 2: OVERVIEW OF THE SWITCH 4005
Minimum Requirements
for Normal Operation
The following minimum components are required for normal operation of the
Switch 4005:
■Two fan trays (four fans total)
■One 300 Watt AC power supply
■One Switch Fabric Management Module (SFMM) operating with system
software
■The number and type of interface modules that are appropriate for your
network connectivity needs
■Blank faceplates that cover all empty module slots and the second power
supply bay (if a second power supply is not installed).
Module Slots in the
Chassis
You insert modules vertically into the chassis slots so that the slot number shows
through a hole in the module faceplate. As shown in Figure 1, the slots for
interface modules are numbered from left to right, starting with number 1 and
continuing to 12. The two center slots are numbered M1 and M2 because they
exist solely to contain Switch Fabric Management Modules (SFMMs). An SFMM
can be placed in either of these slots.

Building a System You can build a complete system from component items that are ordered
separately, or you can simplify your installation by purchasing a preconfigured
starter kit and adding components to it as necessary.
A starter kit consists of a standard chassis (two fan trays, one power supply, one
SFMM) and a variety of preinstalled Fast Ethernet or Gigabit Ethernet Interface
Modules to which you can add additional interface modules of your choice. Starter
kits are designed to reduce installation time. For details on the available starter kit
configurations, see your 3Com network supplier.
Servicing a System For service spares purposes, all component items such as fan trays, power supplies,
and modules can be purchased separately at any time. Check with your network
supplier to see if they stock spare components, provide service, or resell 3Com
service agreements.

14 CHAPTER 2: OVERVIEW OF THE SWITCH 4005
Switch Backplane
Architecture
A star-wired scheme of traces inside the chassis, which is called the backplane, is
used to connect each interface module slot to the Switch Fabric Management
Module (SFMM) slots. A module, fan tray, or power supply connects to the
backplane when it is inserted into a slot and its connectors engage the connectors
that are inside the chassis.
As shown in Figure 3, the Switch 4005 backplane design offers:
■12 Gbps of non-blocking bandwidth capacity
■Passive design, meaning that there are no active components that can fail
■Support for dual, redundant Switch Fabric Management Modules (SFMMs)
■Support for system communication between the SFMM and interface modules
for control signals, detection, and other management activities.
Figure 3 Backplane Architecture of the Switch 4005
The backplane connector on each module provides easy access to all the services
from the Switch 4005 backplane:
■a data channel for network traffic between the SFMM and interface modules
■a control channel that passes signals for module detection
■module diagnostics
■LED operation between the SFMM and interface modules
■a Serial Communication Interface (SCI) communications channel that operates
between two SFMMs (if installed) to keep their configurations synchronized
Traffic between ports on the same interface module does not enter the backplane;
that is, the interface modules provide layer 2 and layer 3 switching when the
packet’s destination is a locally attached node. Interface modules send packets
that have non-local destination addresses across the backplane to the SFMM
which then switches the packets to the appropriate interface module.

16 CHAPTER 3: SITE REQUIREMENTS AND PRODUCT SPECIFICATIONS
Environmental
Specifications
The site for the Switch 4005 should meet the environmental requirements shown
in Table 2:
Ventilation
Requirements
The chassis operates with two fan trays. Each fan tray contains two fans. These
fans pull ambient air into the chassis from vents in the module faceplates and
expel hot air through vents in the back of the fan tray.
Although the fan trays provide the majority of the cooling, the power supplies also
contain fans. Each power supply pulls in ambient air through side vents in the
adjacent chassis wall and expels hot air through its vents in the back.
If a power supply overheats, it shuts itself off.
To ensure that adequate ventilation exists for the Switch 4005:
■Maintain at least 7 cm (2.76 in.) between the sides of the chassis and the
nearest wall or other vertical surface.
■Maintain at least 8 cm (3 in.) between the front of the chassis and another
vertical surface (such as a rack door).
■Maintain at least 91.4 cm (36 in.) at the back of the chassis.
CAUTION: Operate a Switch 4005 chassis with all four fans running. If one fan in
a fan tray fails, replace the fan tray as soon as possible.
Location
Requirements
Install the Switch 4005 in an area that meets the following location requirements:
■The surface on which you want to place the Switch 4005 chassis is level.
■The power source is within approximately 2 meters (6.6 feet) of the location
where you plan to install the Switch 4005.
■Each of the power supplies is connected to its own dedicated circuit. Do not
connect the power supplies to a single power strip.
■There is a sufficient amount of space on each side of the Switch 4005 chassis
to accommodate any cables along the side of the chassis.
■There is at least 91.4 cm (36 in.) at the back of the chassis to service power
supplies and fans.
■If the chassis is the first device in your rack, then mount it about 10.2 cm (4 in.)
above the floor.

Location Requirements 17
■The following list shows the amount of rack space that is needed to install a
Switch 4005 chassis in a Telco rack or a Metric rack:
■Height — 23 cm / 9 in.
The height of the chassis, allowing for some extension beyond the location
of the upper and lower unit dividing lines.
■Telco Rack Unit — 5 RU
The unit of measure is 1 Rack Unit (1.75 in. or 4.45 cm).
■Metric Rack Unit — 10 SU
The unit of measure is 1 System Unit (25 millimeters).
■Front clearance — 8 cm / 3 in.
This is the recommended minimum space required between the front of the
chassis and another vertical surface (such as a rack door). Your cabling may
require that you leave the rack door open.
Precautionary
Guidelines
■Safety regulations stipulate that the table, shelf, or rack on which the Switch
4005 rests can support at least 61.8 kg (136.5 lb), which is three times the
weight of a fully loaded Switch 4005 chassis.
■To reduce the possibility of personal injury or serious damage to the chassis, use
at least two people to install the chassis. This is especially important for rack
installations, because you must hold the chassis in place while you secure it to
the rack.
■If you are installing the Switch 4005 in a rack, first ensure that the rack is
installed properly according to the manufacturer’s instructions, which may
include steps such as:
■Ground the rack in accordance with the rack manufacturer’s instructions.
■Bolt the rack to the floor.
■Make certain that the rack is properly aligned and squared. Use a framing
tool to ensure that the rack is squared.
■Use the following guidelines to tighten screws to Torque Specification:
■Module faceplate screws —1.3 in/lb (inch-pounds)
■Power supplies and fan trays to the chassis —1.3 in/lb
■#10 screws for holding the chassis onto a rack —22-25 in/lb
To ensure that you tighten screws to Torque Specification, use a torque
screwdriver.

18 CHAPTER 3: SITE REQUIREMENTS AND PRODUCT SPECIFICATIONS
Power Requirements This section outlines the power requirements for the Switch 4005 300-watt AC
power supply (Model Number 3C16822). Table 3 lists power specifications for the
chassis.
The power supplies are autosensing; that is, a power supply can automatically
sense the type of input voltage to which it is being connected at the electrical
outlet.
If a power supply overheats, it shuts itself off.
Power Cords One power cord per power supply is required. If you have two power supplies
installed in the chassis, 3Com recommends that you connect them to separate,
dedicated power outlets. The power cord that you require depends on your
country location. The correct power cord should be in your chassis shipping box.
If you do not have the correct power cord, contact your supplier.
Safety Information This section lists warning notices to read before you install the Switch 4005 and its
components.
WARNING: The Switch 4005 chassis and its components must be installed,
maintained, or replaced only by trained service personnel. This guide assumes that
the network administrator has a working knowledge of local area network (LAN)
operations. Furthermore, this guide assumes that the network administrator has
obtained appropriate technical training and experience to perform tasks in service
access areas of network equipment, to be aware of electrical hazards that exist in
performing these tasks, and to take steps that minimize the danger to themselves
or other persons. If you have questions on installation tasks, contact your network
supplier or 3Com technical support. For contact information, see Appendix A.
WARNING: To maintain proper cooling in the chassis and maintain safety
compliance, make certain that blank faceplates cover any empty module slots or
power supply slots.
WARNING: Hazardous energy levels exist inside of the Switch. Do not place hands
or objects into the switch or touch components on an inserted module.
WARNING: Safety regulations state that the selected table, shelf, or rack must be
able to support at least three times the weight of a fully loaded Switch. A fully
loaded Switch 4005 chassis weighs approximately 20.6 kg (45.5 lb). Therefore,
the selected table or shelf must support at least 61.8 kg (136.5 lb).
