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.
To run Express Setup:
Step 1
Verify that no devices are connected to the switch, because during Express Setup, the
switch acts as a DHCP server. If your PC has a static IP address, before you begin you
should change your PC settings to temporarily use DHCP.
Step 2
Connect the AC power cord to the switch and to a grounded AC outlet. The power-on
self-test (POST) begins. During POST, the LEDs blink while a series of tests verify that the
switch functions properly.
Step 3
Wait for the switch to complete POST. It might take several minutes for the switch to
complete POST.
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.
POST errors are usually fatal. Call Cisco Systems immediately 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.
If the LEDs above the Mode button
begin to blink after you press the
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 “Resetting the
Switch” section on page 23.
Step 6
Verify that the switch is in Express Setup mode by confirming that all LEDs above the
Mode button are green. (On some switch models, the RPS LED remains off.)
