express setup is a browser-based program that you can use to set up and configure the switch. you assign the ip information so that the switch can connect to local routers and the internet. the ip address is also required if you plan to further configure the switch.
you do not create a username with express setup. express setup provides the mimimum configuration to configure a switch. to create a username for the switch, use the cluster managment suite (cms) or the command-line interface (cli).
before starting express setup, verify that the switch has passed post and that the syst and stat leds are green. for information about troubleshooting a post failure, see the “understanding post results” section on page 4-2. you cannot start express setup until post has completed.
do not start express setup when there are any devices connected to the switch.
the switch acts as a dhcp server during the express setup procedure, and only the pc or workstation connected to the switch after express startup is started should receive a dhcp address from the switch.
follow these steps to start the express setup program:
step 1 verify that no devices are connected to the switch.
step 2 press and hold the mode button, as shown in figure 1-4, until the four leds above the mode button turn green. this takes approximately 3 seconds.

step 3 release the mode button.
if all of the leds begin to blink after you press the mode button, release it. blinking leds mean that the switch has already been configured and cannot go into express setup mode. for more information, see the “clearing the switch ip address and configuration” section on page 4-2.
step 4 connect the ethernet cable (not included) to a 10/100 ethernet port or small form-factor pluggable (sfp) module port on the front panel of the switch, as shown in figure 1-5.
do not connect the switch to any device other than the pc or workstation being used to configure it.

step 5 connect the other end of the cable to the ethernet port on the pc or workstation.
verify that the port status leds on both connected ethernet ports are green.
step 6 wait approximately 30 seconds after the port leds turn green, and launch a web browser on your pc or workstation.
step 7 enter the ip address 10.0.0.1, as shown in figure 1-6, and press enter.

if the express setup does not run, or the express setup home page does not appear in your browser:
1?did you wait 30 seconds after connecting the switch and pc or workstation before entering the ip address in your browser?
if not, wait 30 seconds, and re-enter 10.0.0.1 in the browser, and press enter.
2?did you enter the wrong address in the browser, or is there an error message displayed in the browser window?
re-enter 10.0.0.1 in the browser, and press enter.
3?did you connect a crossover instead of a straight-through ethernet cable between an ethernet port of the switch and the ethernet port of the pc or workstation, as shown figure 1-5.
see figure b-11 on page b-9 for instructions on identifying a crossover cable.
on switches running cisco ios release 12.1(14)ea1 or later, you can use the mdix auto command in the cli to enable the automatic crossover feature. when the automatic crossover feature is enabled, the switch detects the required cable type for copper ethernet connections and configures the interfaces accordingly. therefore, you can use either a crossover or a straight-through cable for connections to a copper 10/100 or 10/100/1000 port on the switch, regardless the type of device on the other end of the connection.
the automatic crossover feature is disabled by default. for configuration information for this feature, refer to the switch software configuration guide or the switch command reference.
if not, reconnect the cable to the ethernet port on the switch and pc or workstation. wait 30 seconds before entering 10.0.0.1 in the browser.
did you verify that post successfully ran before starting express setup?
if not, make sure that only the syst and stat leds are green before pressing the mode button to begin express setup.
the rest of this chapter explains how to configure a switch by using the express setup web page. to configure the switch by using the command-line interface (cli)-based setup program, see appendix d, “quick setup by using the cli-based setup program.”
