Checklist Recommendation
Did you verify that POST ran
successfully before starting Express
Setup?
If not, make sure that only the SYST LED and ACTV LED
are green before you press the Mode button to enter the
Express Setup mode.
POST errors are usually fatal. Contact your Cisco technical
support representative if your switch fails POST.
Did you press the Mode button while
the switch was still running POST?
If yes, wait until POST completes. Power cycle the switch.
Wait until POST completes. Confirm that the SYST LED
and ACTV LED are green. Press the Mode button to enter
Express Setup mode.
Did you try to continue without
confirming that the switch was in
Express Setup mode?
Verify that all LEDs next to the Mode button are green. If
not, press and hold the Mode button to enter Express Setup
mode.
Does your PC or laptop have a static IP
address?
If yes, change your PC or laptop settings to temporarily use
DHCP before connecting it to the switch.
Did you connect the Ethernet cable to
the console port instead of a
10/100/1000 Ethernet port or the
management port on the switch?
If yes, disconnect the cable from the console port. Connect
the cable to an Ethernet port on the switch. Wait 30 seconds
before you enter 10.0.0.1 in the browser.
Did you wait 30 seconds after you
connected the switch and the PC or
laptop before you entered the IP
address in your browser?
If not, wait 30 seconds, reenter 10.0.0.1 in the browser, and
press Enter.
Did you enter the wrong address in the
browser, or is there an error message?
If yes, reenter 10.0.0.1 in the browser, and press Enter.
