Running Express Setup
Running Express Setup
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 access the switch through the IP address for further 
configuration.
NoteTo use the CLI-based initial setup program, see Appendix C, “Configuring the Switch with the 
CLI-Based Setup Program,” in the switch hardware guide.
You need this equipment:
PC with Windows Vista, XP, or 2000 
Browser (Internet Explorer 5.5, 6.0, 7.0, Firefox 1.5, 2.0, 3.0 or later) with JavaScript enabled
Straight-through or crossover Category 5 Ethernet cable 
NoteBefore running Express Setup, disable any pop-up blockers or proxy settings in your browser and any 
wireless client running on your PC.
Step 1Make sure that nothing is connected to the switch.
Step 2During Express Setup, the switch acts as a DHCP server. If your PC has a static IP address, temporarily change your 
PC settings before you use DHCP.
NoteWrite down the static IP address. You will need this IP address in Step 13.

Running Express Setup
Step 3Power the switch.
AC power switches: Plug the AC power cord into the 
switch power supply and into a grounded AC outlet.
DC power switches: See the wiring instructions in the 
hardware installation guide on Cisco.com.
Step 4Approximately 30 seconds after the switch powers on, it begins the power-on self-test (POST), which can take up to 
5 minutes to complete. 
During POST, the SYSTEM LED blinks green, and the XPS, STATUS, DUPLEX, and SPEED LEDs turn solid 
green. 
When POST is complete, the SYSTEM LED is green, the MAST LED is green if the switch is acting as stack master, 
and the other LEDs turn off.
NoteBefore going to the next step, wait until POST is complete. 
Troubleshooting:
If the SYST LED blinks green, does not turn green, or turns amber, contact your Cisco representative or reseller. The 
switch failed the power-on self-test (POST).
Step 5Press and hold the Mode button until all the LEDs next to 
the Mode button turn green. (The XPS LED remains off 
on some switch models.)
You might need to hold the button for more than 3 
seconds. 
The switch is now in Express Setup mode.
Troubleshooting:
If the LEDs next to the Mode button blink when 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 to the Default Settings” section on page 20.

Running Express Setup
Step 6Connect a Category 5 Ethernet cable to a port:
Any 10/100/1000 Ethernet port on the switch front 
panel
The RJ-45 management port on the switch rear panel
Connect the other end of the cable to the Ethernet port on 
your PC. 
Wait until the port LEDs on the switch and your PC or 
laptop are green or blinking green. Green LEDs mean a 
successful connection.
Troubleshooting:
If the port LEDs do not turn green after about 30 seconds, 
make sure that: 
You connected the Ethernet cable to one of the 
downlink switch ports (not to the console port). 
You are using an undamaged Category 5 or 6 
Ethernet cable.
The other device is turned on. 
Step 7Start a browser session on the PC, and enter the IP address 10.0.0.1. When prompted, enter the default password, 
cisco.
NoteThe switch ignores text in the username field.
The Express Setup window appears.
Troubleshooting:
If the Express Setup window does not appear, make sure that any browser pop-up blockers or proxy settings are 
disabled and that any wireless client is disabled on your PC or laptop.

Running Express Setup
Step 8Enter this information in the Network Settings fields:
NoteAll entries must be in English letters.
In the Management Interface (VLAN ID) field, the default is 1. 
NoteWe recommend that you use the default VLAN value. During Express Setup, VLAN 1 is the only VLAN on 
the switch. 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 switch IP address. 
In the Subnet Mask field, click the drop-down arrow, and select a 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.
NoteYou must change the default password, cisco.
(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. 
Step 9(Optional) You can enter the Optional Settings information now or enter it later by using the device manager 
interface.
You can enter other administrative settings in the Optional Settings fields. For example, the optional administrative 
settings identify and synchronize the switch for enhanced management. NTP automatically synchronizes the switch 
clock with the network clock. You can manually set the system clock if the switch should have different settings.

Running Express Setup
Step 10(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. 
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. 
(Optional) In the Enable IPv6 field, click Enable to enable IPv6 on the switch.
NoteEnabling IPv6 restarts the switch when you complete Express Setup. 
Step 11Click Submit to save your changes and wait 60 seconds to complete the initial setup.
After you click Submit and 60 seconds elapsed :
The switch is configured and exits Express Setup mode. 
The browser displays a warning message and tries to connect with the earlier switch IP address. Typically, 
connectivity between the PC and the switch is lost because the configured switch IP address is in a different 
subnet from the IP address on the PC.
For more information about Express Setup fields, see the online help for the Express Setup window.
Step 12Disconnect the switch from the PC, and install the switch in your network. See the “Installing the Switch” section 
on page 10.
Step 13If you changed the static IP address on your PC in Step 2, change it to the previously configured static IP address.

Managing the Switch
Managing the Switch
After completing Express Setup and installing the switch in your network, you can use these options for 
configuration:
Device Manager
Cisco Network Assistant
Command-Line Interface
Other Management Options
Device Manager
The simplest way to manage the switch is by using the device manager in the switch memory. This is a 
web interface that offers quick configuration and monitoring. You can access it through a web browser.
Follow these steps:
1.Launch a web browser on your PC or laptop.
2.Enter the switch IP address in the web browser, and press Enter. The device manager page appears.
3.Use the device manager for basic switch configuration and monitoring. Refer to the device manager 
online help for more information.
Step 14See the “Managing the Switch” section on page 8 for information about configuring and managing the switch.
To display the device manager:
1.Start a web browser on your PC or laptop.
2.Enter the switch IP address, username, and password assigned in Step 8 in the browser, and press Enter. 
The device manager page appears.
Troubleshooting:
If the device manager does not appear:
Confirm that the port LED for the switch port connected to your network is green.
Confirm that the PC or laptop that you are using has network connectivity by connecting it to a well-known web 
server in your network. If there is no network connection, troubleshoot the network settings on the PC or laptop.
Make sure that the switch IP address in the browser is correct.
If the switch IP address in the browser is correct, the switch interface LED is green, and the PC or laptop has 
network connectivity, continue troubleshooting by reconnecting the PC or laptop to the switch. Configure a 
static IP address on the PC or laptop that is in the same subnet as the switch IP address.
When the LED on the switch port connected to the PC or laptop is green, re-enter the IP address of the switch 
in a browser to display the device manager. When the device manager appears, you can continue with the 
configuration.
