3 Running Express Setup
When you first set up the switch, you should use Express Setup to enter the initial IP information. Doing this enables the switch
to connect to local routers and the Internet. You can then access the switch through the IP address for further configuration.
You need this equipment to set up the switch:
•A PC with Windows 2000 or XP installed
•A web browser (Internet Explorer 6.0, 7.0, Firefox 1.5, 2.0, Windows Vista OS) with JavaScript enabled
•A straight-through or crossover Category 5 Ethernet cable to connect your PC to the switch
Before running Express Setup, disable any pop-up blockers or proxy settings in your browser software and any wireless client
running on your PC.
During Express Setup, the switch acts as a DHCP server. If your PC has a static IP address, change your PC settings before you
begin to temporarily use DHCP.
To run Express Setup:
Step 1 Make sure that nothing is connected to the switch.
Step 2 Power the switch by connecting the AC power cord to
the switch power supply and to a grounded AC outlet.
Step 3 When the switch powers on, it begins the power-on self-test (POST). During POST, the LEDs blink while tests verify
that the switch functions properly.
Wait for the switch to complete POST, which can take several minutes.
Step 4 Verify that POST has completed by confirming that the SYST LED remains green. If the switch fails POST, the SYST
LED turns amber. See the “In Case of Difficulty” section on page 14 if your switch fails POST.
Step 5 Press and hold the Mode button for 3 seconds. When all
of the LEDs above the Mode button turn green, release
the Mode button.
Step 6 If the LEDs above the Mode button blink after you press the button, release it. Blinking LEDs mean that the switch
is already configured and cannot go into Express Setup mode. For more information, see the “Resetting the Switch”
section on page 15.
Step 7 Verify that the switch is in Express Setup mode. Make sure that all LEDs above the Mode button are green. (On
some switch models, the RPS LED remains off.)
Step 8 Connect a Category 5 Ethernet cable to any Ethernet
port on the switch front panel.
Connect the other end of the cable to the Ethernet port
on your PC.

Step 9 Verify that the LEDs on both Ethernet ports are green.
Wait 30 seconds.
Step 10 Launch a web browser on your PC. Enter the IP address
10.0.0.1 in the web browser, and press Enter.
Step 11 The Express Setup Basic Settings page appears. If it does not appear, see the “In Case of Difficulty” section on
page 14.
Step 12 Enter this information in the Network Settings fields:
•In the Management Interface (VLAN ID) field, the default is 1. Enter a new VLAN ID only if you want to
change the management interface through which you manage the switch and to which you assign IP
information. The VLAN ID range is 1 to 1001.
•In the IP Address field, enter the IP address of the switch. In the IP Subnet Mask field, click the drop-down
arrow, and select an IP Subnet Mask.
•In the Default Gateway field, enter the IP address for the default gateway (router).
•Enter your password in the Switch Password field. The password can be from 1 to 25 alphanumeric characters,
can start with a number, is case sensitive, allows embedded spaces, but does not allow spaces at the beginning
or end. In the Confirm Switch Password field, enter your password again.

5
Refreshing the PC IP Address
After you complete Express Setup, you should refresh the PC IP address:
•For a dynamically assigned IP address, disconnect the PC from the switch, and reconnect the PC to the network. The
network DHCP server assigns a new IP address to the PC.
•For a statically assigned IP address, change it to the previously configured IP address.
Step 13 (Optional) You can enter the Optional Settings information now or enter it later by using the device manager
interface:
•In the Host Name field, enter a name for the switch. The host name is limited to 31 characters; embedded
spaces are not allowed.
•In the System Contact field, enter the name of the person who is responsible for the switch. In the System
Location field, enter the wiring closet, floor, or building where the switch is located.
•In the Telnet Access field, click Enable if you are going to use Telnet to manage the switch by using the
command-line interface (CLI). If you enable Telnet access, you must enter a Telnet password.
•In the Telnet Password field, enter a password. The Telnet password can be from 1 to 25 alphanumeric
characters, is case sensitive, allows embedded spaces, but does not allow spaces at the beginning or end. In the
Confirm Telnet Password field, re-enter the Telnet password.
•In the SNMP field, click Enable to enable Simple Network Management Protocol (SNMP). Enable SNMP only
if you plan to manage switches by using CiscoWorks 2000 or another SNMP-based network-management
system.
If you enable SNMP, you must enter a community string in the SNMP Read Community field, the SNMP Write
Community field, or both. SNMP community strings authenticate access to MIB objects. Embedded spaces are
not allowed in SNMP community strings. When you set the SNMP read community, you can access SNMP
information, but you cannot modify it. When you set the SNMP write community, you can both access and
modify SNMP information.
Step 14 Click Submit to save your settings, or click Cancel to clear your settings.
When you click Submit, the switch is configured and exits Express Setup mode. The PC displays a warning message
and then tries to connect with the new switch IP address. If you configured the switch with an IP address that is in
a different subnet from the PC, connectivity between the PC and the switch is lost.
Step 15 Disconnect the switch from the PC, and install the switch in your network. See the “Managing the Switch” section
on page 6 for information about configuring and managing the switch.
If you need to rerun Express Setup, see the “Resetting the Switch” section on page 15.

4 Managing the Switch
After you complete Express Setup and install the switch in your network, use the device manager or other management options
described in this section for further configuration.
Using the Device Manager
The simplest way to manage the switch is by using the device manager in the switch memory. This web interface offers quick
configuration and monitoring. You can access the device manager from anywhere in your network through a web browser.
Follow these steps:
1. Launch a web browser on your PC or workstation.
2. Enter the switch IP address in the web browser, and press Enter. The device manager page appears.
3. Use the device manager to perform basic switch configuration and monitoring. Refer to the device manager online help for
more information.
4. For more advanced configuration, download and run the Cisco Network Assistant, which is described in the next section.
Downloading Cisco Network Assistant
Cisco Network Assistant is a software program that you download from Cisco.com and run on your PC. It offers advanced
options for configuring and monitoring multiple devices, including switches, switch clusters, switch stacks, routers, and access
points. Network Assistant is free—there is no charge to download, install, or use it.
Follow these steps:
1. Go to this Web address: http://www.cisco.com/go/NetworkAssistant.
You must be a registered Cisco.com user, but you need no other access privileges.
2. Find the Network Assistant installer.
3. Download the Network Assistant installer, and run it. (You can run it directly from the Web if your browser offers this
choice.)
4. When you run the installer, follow the displayed instructions. In the final panel, click Finish to complete the Network
Assistant installation.
Refer to the Network Assistant online help and the getting started guide for more information.
Command-Line Interface
You can enter Cisco IOS commands and parameters through the CLI. Access the CLI either by connecting your PC directly to
the switch console port or through a Telnet session from a remote PC or workstation.
Follow these steps:
1. Connect the supplied RJ-45-to DB-9 adapter cable to the standard 9-pin serial port on the PC. Connect the other end of the
cable to the console port on the switch.
2. Start a terminal-emulation program on the PC.
3. Configure the PC terminal emulation software for 9600 baud, 8 data bits, no parity, 1 stop bit, and no flow control.
4. Use the CLI to enter commands to configure the switch. See the software configuration guide and the command reference
for more information.

7
Other Management Options
You can use SNMP management applications such as CiscoWorks Small Network Management Solution (SNMS) and HP
OpenView to configure and manage the switch. You also can manage it from an SNMP-compatible workstation that is running
platforms such as HP OpenView or SunNet Manager.
The Cisco IE2100 Series Configuration Registrar is a network management device that works with embedded Cisco Networking
Services (CNS) agents in the switch software. You can use IE2100 to automate initial configurations and configuration updates
on the switch.
See the “Accessing Help Online” section on page 15 for a list of supporting documentation.
5 Planning Switch Stacks
Before connecting the switches in a stack, keep in mind these switch stack guidelines:
•Connect only Catalyst 2975 switches in a switch stack. The Catalyst 2975 switch does not support mixed stack
configurations. You cannot stack Catalyst 2975 switches with Catalyst 3750 switches or Catalyst 3750-E switches.
•Length of cable. Depending on your configurations, you might need different sized cables. If you do not specify the length
of the stack cable, the 0.5-meter cable is supplied. If you need the 1-meter cable or the 3-meter cable, you can order it from
your Cisco supplier.
•Access to the switch rear panel and to the rear of the rack. If you do not have access to the rear panel, make sure that you
cable the switches before you rack-mount them.
For switch dimensions, stack cable part numbers, and additional stacking guidelines, see the switch hardware installation guide
on Cisco.com. For concepts and procedures to manage switch stacks, see the switch software configuration guide and the stack
compatibility guide also on Cisco.com.
Powering Guidelines
Consider the following guidelines before you power the switches in a stack:
•The sequence in which the switches are initially powered on might affect the switch that becomes the stack master.
•If you want a particular switch to become the stack master, power on that switch first. This switch becomes the stack master
and remains the stack master until a master re-election is required. After 20 seconds, power on the remaining switches in
the stack.
•If you have no preference for which switch becomes the stack master, power on all the switches in the stack within a
20-second timeframe. These switches participate in the stack master election. Switches powered on after the 20-second
timeframe do not participate in the election.
•Power off a switch before you add it to or remove it from an existing switch stack.
For more information on stack master elections, see the “Managing Switch Stacks” chapter in the switch software configuration
guide on Cisco.com.

8
Cabling Guidelines
These illustrations show the recommended switch stack configurations with redundant stack cabling connections for optimized
stack bandwidth. For more configuration examples, see the hardware installation guide on Cisco.com.
In this example, the stack uses the 0.5-meter stack cable to make redundant connections.
In this example, the stacks use both 0.5- and 3-meter stack cables to make redundant connections.

6 Rack-Mounting
This section covers basic 19-inch rack-mounting and switch port connections. For alternate mounting procedures, such as
installing the switch in a 24-inch rack or on a wall, and for additional cabling information, see the hardware installation guide
on Cisco.com.
Equipment That You Supply
You need a number-2 Phillips screwdriver to rack-mount the switch.
Before You Begin
Before installing the switch, verify that these guidelines are met:
•Clearance to front and rear panels is such that
– Front-panel indicators can be easily read.
– Access to ports is sufficient for unrestricted cabling.
•Confirm that you have access to the switch rear panel to connect the optional RPS 2300 or the RPS 675. If you do not have
access to the rear panel, you should cable the switches before you rack-mount them.
•Verify that the AC power cord can reach from the AC power outlet to the connector on the switch rear panel.
•Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting fixtures. Make sure
the cabling is safely away from other devices that might damage the cables.
•Airflow around the switch and through the vents is unrestricted.
•Temperature around the unit does not exceed 113°F (45°C). If the switch is installed in a closed or multirack assembly, the
temperature around it might be greater than normal room temperature.
•Humidity around the switch does not exceed 85 percent.
•Altitude at the installation site is not greater than 10,000 feet.
•For copper connections on Ethernet ports, cable lengths from the switch to connected devices can be up to 328 feet (100
meters).
•For cable lengths for SFP-module connections, see the hardware installation guide on Cisco.com and the documentation
that shipped with the module.
