• 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 11

Disconnect the switch from the PC, and install the switch in your network.

Step 12

If you changed the static IP address on your PC in Step 2, change it to the previously configured static IP address.

Step 13

You can now manage the switch by using Cisco Network Assistant, Device Manager, or both. See

for information about configuring and managing the switch. We strongly recommend that you download Cisco Network

Assistant from Cisco.com and use it to manage the switch.

You can display Device Manager by following these steps:

• Start a web browser on your PC or laptop.

• Enter the switch IP address, username, and password in the web browser, and press Enter. The Device Manager

page appears.

If 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 you are using to access the switch has network connectivity by connecting 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. For example:

• If your switch IP address is 172.20.20.85 and your PC or laptop IP address is 172.20.20.84, both devices

• If your switch IP address is 172.20.20.85 and your PC or laptop IP address is 10.0.0.2, the devices are in

◦ When the LED on the switch port connected to the PC or laptop is green, reenter the IP address of the switch

in a web browser to display Device Manager. When Device Manager appears, you can continue with the switch

configuration.
