1 About this Guide

This guide provides instructions on how to use Express Setup to initially configure your Catalyst
switch. Also covered are switch management options, basic rack-mounting procedures, stacking
procedures, port and module connection procedures, power connection procedures, and
troubleshooting help.

For additional installation and configuration information for Catalyst 3750 switches, see the
Catalyst 3750 documentation on Cisco.com. For system requirements, important notes, limitations,
open and resolved bugs, and last-minute documentation updates, see the release notes, also on
Cisco.com.

When using the online publications, refer to the documents that match the Cisco IOS software version
running on the switch. The software version is on the Cisco IOS label on the switch rear panel.

For translations of the warnings that appear in this publication, see the Regulatory Compliance and
Safety Information for the Catalyst 3750 Switch that accompanies this guide.

3 Running Express Setup

When you first set up the switch, you should use Express Setup to enter the initial IP information. 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.

To run Express Setup:

Step 1

Step 2

Step 3

Step 4

Step 5

Make sure that nothing is connected to the switch.

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.

Power the switch by connecting the supplied AC power cord to the switch power
connector and to a grounded AC outlet.

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.

Verify that POST has completed by confirming that the SYST LED remains green. If the
switch fails POST, the SYST LED turns amber.

POST errors are usually fatal. Contact your Cisco technical support representative if your
switch fails POST.

Press and hold the Mode button for
3 seconds. When all of the LEDs left
of the Mode button turn green,
release the Mode button.

If the LEDs left of the Mode button
begin to blink after you press the
button, release it. Blinking LEDs

Verify that the switch and PC Ethernet ports LEDs are green.

Wait 30 seconds.

Start a web browser on your PC.
Enter the IP address 10.0.0.1 in the
web browser, and press Enter.

The Express Setup page appears. If it does not appear, see the “In Case of Difficulty”
section for help.

Step 11

Step 12

Step 13

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. 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.

(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.

• Enter the date, time, and time zone information in the System Date, System Time, and
Time Zone fields. Click Enable to enable daylight saving time.

(Optional) Click the Advanced Settings tab on the Express Setup window, and enter the
advanced settings now or enter them later by using the device manager interface.

Step 14

Step 15

(Optional) Enter this information in the Advanced Setting fields:

• 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.

• In the System Contact and System Location fields, enter a contact name and the wiring
closet, floor, or building where the switch is located.

(Optional) You can enable Internet Protocol version 6 (IPv6) on the switch. From the
Advanced Settings tab, check the Enable IPv6 check box.

Note Enabling IPv6 restarts the switch when you complete Express Setup.

Step 16

Step 17

To complete Express Setup, click Submit from the Basic Settings or the Advanced Settings
tab 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 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.

Disconnect the switch from the PC, and install the switch in your production network. See
the “Managing the Switch” section for information about configuring and managing the
switch.

If you need to rerun Express Setup, see the “Resetting the Switch” section.

7

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.

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 that is in the switch memory.
This is an easy-to-use web interface that 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.
