2Quick Installation Guide
Installing the
System
To install the SuperStack II Switch 3900 or Switch 9300 system in your
network, follow the steps in this section.
Audience This guide is intended only for trained technical personnel. Do not
attempt to install or service a SuperStack II Switch 3900 or Switch 9300 if
you do not have the proper training. For training information, call
1-800-NET-3COM in the United States and Canada. For training
information elsewhere, visit the 3Com website at www.3com.com.
WARNING: For your safety and to ensure adequate cooling airflow, keep
blank faceplates over any empty slots on the Switch 3900.
Install the SuperStack II Switch 3900 or Switch 9300 system in an area
that meets the requirements in Table 1.
For more information on site requirements, see Appendix B in the Getting
Started Guide for your system.
Check the packing slip to verify that you have all of the components that
you ordered.
The system is shipped with one internal power supply. If you have ordered
a redundant power supply or uninterruptible power supply for the
system, have it available for installation.

Quick Installation Guide 3
Before You Begin
Before you install the system:
■Move the system close to where you plan to install it.
■Have a Number 1 Phillips screwdriver available.
■Have the hardware kit that comes with the system available. See
Ta b l e 2 .
Determine whether you are installing the system on a tabletop or in a
distribution rack.
For complete installation instructions, see Chapter 2 in the Getting
Started Guide for your system.
WARNING: Hazardous energy exists within the SuperStack II
Switch 3900 and Switch 9300 systems. Follow instructions in the Getting
Started Guide to avoid electric shock or equipment damage. Many
installation and troubleshooting procedures should be performed only by
trained technical personnel.
The system operates using a single power supply assembly and is shipped
with one internal power supply.
■You can connect an uninterruptible power supply (UPS).
■You can also connect a redundant power supply (RPS).
These additional power supplies are orderable and shipped separately.
Contact your network supplier.
For instructions on how to install the RPS, see the Advanced RPS
Power Module Type 2 User Guide.

4Quick Installation Guide
If you have ordered one or two additional Gigabit Ethernet modules for
your SuperStack II Switch 3900 system, you are now ready to install the
modules.
CAUTION: Electrostatic discharge (ESD) can damage components on a
module, causing complete or intermittent failures. ESD damage occurs
when the module is improperly handled. When handling modules, be
sure to read and follow the ESD safety information provided in the
Module Installation Guide.
For installation instructions, see the 1000BASE-SX/1000BASE-LX Gigabit
Ethernet Module Installation Guide that is shipped with the module.
Cable your system for connecting these elements to your network:
■10/100BASE-T connectors (3900 only)
■1000BASE-SX or LX connectors (3900 and 9300)
■10BASE-T out-of-band port connector (9300 only)
■Console port (3900 and 9300)
For information on cabling ports, see Chapter 3 in the Getting Started
Guide for your system.
Place the system near an easily accessible power outlet because the only
way that you can power the system up or down is to insert or remove the
power cord from the power source. To get your system powered up and
ready to operate:
1For the Switch 3900, verify that each unused slot is covered with a blank
faceplate.
To view possible error messages in the Administration Console while the
system is running power-up diagnostics, connect a terminal, workstation,
or PC with terminal emulation software to the system’s Console port.
2On the back panel of either the Switch 3900 or the Switch 9300, plug the
power cord into the power receptacle.
CAUTION: To prevent a possible fire hazard, be sure to fully insert the
power cord.
3Plug the other end of the power cord into a power outlet.

LEDs and Power-up Diagnostics
Your system runs diagnostic software at power up. This software verifies
that every component in the system is operating correctly. If any
component fails during power-up diagnostics, the system either fails to
power up or, for the Switch 3900, it prevents faulty modules from coming
online.
For diagnostic messages, view the system display in the Administration
Console (if you have connected the system to a workstation).
For the Switch 3900, when the system comes up, verify which modules, if
any, have failed diagnostics by checking the module LEDs.
The system and port LEDs are described in Table 3.

6Quick Installation Guide
Your system is shipped from the factory with IEEE 802.1D bridging set to
disabled. To configure system features for your particular networking
environment, you must first establish management access.
Initially, you can only manage your system locally through a direct
terminal connection to the Console port. You use this interface to
configure additional access mechanisms, as shown in Table 4.
For more information on access mechanisms, see Chapter 6 in the
Getting Started Guide for your system or Chapter 2 in the
Implementation Guide.
Defining an Interface
Once you have configured initial access, you can manage your system in
one of these ways:
■In-band — Manages the system and its attached LANs over the same
network that carries your regular data traffic. You configure an IP
address on any Ethernet port.
■Out-of-band (9300) —Uses a dedicated network for management
data. You configure a system management interface for the Ethernet
10BASE-T out-of-band port and assign it an IP address.
Ta b l e 4 System Management Access Mechanisms

Mechanism Access Description Interface
Terminal Connect directly to the Administration Console
and stay attached during system reboots
Console port
Modem Access the Administration
Console from remote sites
Console port
IP ■Access the Administration Console using the
rlogin or Telnet commands
■Use an external SNMP management
application (such as the 3Com Transcend®
applications) to communicate with your
system’s SNMP agent
■Use the Web Management suite of
applications that is embedded in the
software
Ethernet port that
is assigned an IP

Configure System
for Management 8

Quick Installation Guide 7
■Modem — Uses a modem to establish a connection between your
current Administration Console session and the Console port. When
you have configured the modem from the Administration Console
menu system, the Console appears to be directly connected to the
external modem.
These management access mechanisms are described briefly next and
more completely in the SuperStack II Switch 3900 and Switch 9300
Implementation Guide.
In-band Management (Switch 3900 and 9300). To manage your
network in band:
1From the top level of the Administration Console, enter:
ip interface define
2Enter the IP address of the interface.
3Enter the subnet mask. Press Return or Enter to accept the default or
current value.
4Enter the index number of the VLAN that you want to associate with the
IP address.
For more information about configuring VLANs, see the SuperStack II
Switch 3900 and Switch 9300 Implementation Guide.
Out-of-band Management (Switch 9300 only). To manage your
network out of band:
1From the top level of the Administration Console, enter:
ip interface define
2Enter the IP address for the out-of-band port.
3Enter the subnet mask. Press Return or Enter to accept the default or
current value.
4Enter system as the interface type.
