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, and troubleshooting help.

For additional installation and configuration information for Catalyst 3750-E switches, see the
Catalyst 3750-E 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-E and Catalyst 3560-E Switch that accompanies this guide.

2 Taking Out What You Need

Follow these steps:

1. Unpack and remove the switch and the accessory kit from the shipping box.

2. Return the packing material to the shipping container, and save it for future use.

3. Verify that you have received the items shown on page 3. If any item is missing or damaged,

contact your Cisco representative or reseller for instructions. Some switch models might include
additional items that are not shown on page 3.

4. For switches with the optional 1150-W power supply module (model C3K-PWR-1150WAC),
install the power supply in the switch as described in the installation notes after you rack-mount
the switch.

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 5.5, 6.0, Netscape 7.1 or later) with JavaScript enabled.

• A straight-through or crossover Category 5 Ethernet cable to connect your PC to the switch.

Disable any pop-up blockers or proxy settings in your browser software and any wireless client
running on your PC.

To run Express Setup:

Step 1

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.

Step 2

Power the switch.

For AC-powered switches, connect the AC
power cord to the switch power supply and
to a grounded AC outlet.

For DC-powered switches, see the wiring
instructions in the hardware installation
guide on Cisco.com.

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 22 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 23.

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
10/100/1000 Ethernet port on the switch
front panel or to the Ethernet management
port on the rear 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 switch prompts you for the default switch password. Enter the default password, cisco.

Note The switch ignores text in the username field.

Step 12

The Express Setup Basic Settings page appears. If it does not appear, see the “In Case of
Difficulty” section on page 22.

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 4094.

• 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.

Note You must change the password from the default password, cisco.

Step 14

(Optional) Enter this information in the Ethernet Management Port Settings fields:

• In the IP Address field, enter the IP address of the Ethernet management port. In the
IP Subnet Mask field, click the drop-down arrow, and select an IP Subnet Mask.

7

Step 15

(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.

Step 16

(Optional) You can select 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.

8

Step 17

(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 change it. When you set the SNMP write community, you
can both access and change 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.

Step 18

(Optional) You can enable IPv6 on the switch in the Advanced Settings screen. In the Enable
IPv6 field, click Enable to enable IPv6 on the switch.

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

Step 19

To complete Express Setup, click Submit in the Network Settings or the Advanced Settings
screen to save your settings. 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. If you enabled IPv6, the switch restarts.

Step 20

Disconnect the switch from the PC, and install the switch in your production network. See
the “Managing the Switch” section on page 9 for information about configuring and
managing the switch.

If you need to rerun Express Setup, see the “Resetting the Switch” section on page 23.
