Power 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 Catalyst 3650 Switch Hardware Installation Guide on Cisco.com:

http://www.cisco.com/go/cat3650_hw

Observe the POST results. Approximately 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. When POST is complete, the SYSTEM LED turns solid green. The ACTV LED is green if the switch is acting as the active switch.

Note Before going to the next step, wait until POST is complete.

Troubleshooting:

If the SYST LED does not turn solid green, or turns amber, the switch failed the POST. Contact your Cisco representative or reseller.

Press and hold the Mode button until all the LEDs next to the Mode button turn green.

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” section on page 20.

Step 14

Step 15

Click Submit to save your changes and to complete the initial setup.

After you click Submit:

• 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 or laptop and the switch is lost because the configured switch IP address is in a different subnet from the IP address on the PC or laptop.

For more information about Express Setup fields, see the online help for the Express Setup window.

Disconnect the switch from the PC and laptop, and install the switch in your network. See the “Installing the Switch”

section on page 10.

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

See the “Managing the Switch” section on page 7 for information about configuring and managing the switch.

Managing the Switch

After completing Express Setup and installing the switch in your network, you can use these options for configuration:

• Configuration Wizard

• Device Manager

• Cisco Network Assistant

• Command-Line Interface

• Other Management Options

Configuration Wizard

The Configuration Wizard is a Web-based controller user interface (UI) that lets you complete the initial wireless configuration after you configure the IP address, local username, and password or authorization using the authentication server. Using the Web UI, you can configure the controller, WLAN, and radios for all initial operations, establish management parameters, set security policies, access software management commands, configure system logs, and other tasks.

For more information on using the Configuration Wizard, see switch software configuration guide on Cisco.com

Device Manager

The simplest way to manage the switch is by using Device Manager in the switch memory. Use Device Manager for basic switch configuration and monitoring. This web interface offers quick configuration and monitoring. You can access it through a web browser.

To display Device Manager:

OL-29733-01

Step 1 Start a web browser on your PC or laptop.

Catalyst 3650 Switch Getting Started Guide

Managing the Switch

Step 2 Enter the switch IP address, username, and password assigned in Step 9 above, and press Enter.

The Device Manager page appears. Refer to the Device Manager online help for more information.

Troubleshooting:

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 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, then 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 is green on the switch port that is connected to the PC or laptop, reenter the IP

address of the switch in a browser to display Device Manager. When Device Manager appears, continue with the configuration.

Connecting the StackWise Cables

347769

You can stack the Catalyst 3650 switch with other Catalyst 3650 switches. Before connecting the StackWise cables, review the “Planning a Switch Data Stack” section in the Catalyst 3650 Switch Hardware Installation Guide. Always use Cisco-approved StackWise cables to connect the switches.

Caution Removing and installing the StackWise cable can shorten its useful life. Do not remove and install the

cable more often than is absolutely necessary (removing and installing it up to 200 times is supported).

Step 1 Remove the dust covers from the StackWise cables and store them for future use.

A StackWise adapter must be installed in the StackWise port to enable stacking. The default setup is with StackWise adapter blanks installed in the StackWise ports. If StackWise stacking was ordered with the switch, StackWise adapters are already installed in the StackWise ports, and you can proceed to step 4.

Step 2 Remove the StackWise adapter blanks from each destination StackWise port by unscrewing the screws

on the adapter blanks using the Torx T15 Allen key provided in the stacking kit (or a Torx T15 screwdriver), as shown in Figure 5. Store them for future use.

Step 3 Install a StackWise adapter in each destination StackWise port, and secure in place using the supplied

Torx T15 key, or a Torx T15 screwdriver, as shown in Figure 6.

Note It is not necessary to remove the fan modules prior to removal or installation of the StackWise

adapter. If the installation is performed with the system powered-on, the fans must be left in the installed position at all times.

Step 4 Connect the StackWise cable to the StackWise port on the switch rear panel.

a. Align the StackWise cable connector with the StackWise adapter in the StackWise port.

b. Insert it to connect the StackWise cable to the StackWise port, as shown in Figure 7. Make sure that

the Cisco logo is on the top side of the connector.

c. Finger-tighten the screws (clockwise direction).

Verify Port Connectivity

After you connect a device to the switch port, the port LED turns amber for about 30 seconds while the switch establishes a link. The LED turns green when the switch and the attached device are linked. If the LED is off, the device might not be turned on, or there might a problem with the cable or with the adapter installed in the device.

Troubleshooting

This section includes Express Setup troubleshooting, how to reset the switch, how to access help online, and where to find more information.

Express Setup

If Express Setup does not run or if the Express Setup page does not appear in your browser:

Checklist Recommendation

Did you verify that POST ran successfully before starting Express Setup?

Did you press the Mode button while the switch was still running POST?

Did you try to continue without confirming that the switch was in Express Setup mode?

Does your PC or laptop have a static IP address?

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?

Did you wait 30 seconds after you connected the switch and the PC or laptop before you entered the IP address in your browser?

Did you enter the wrong address in the browser, or is there an error message?

Troubleshooting

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.

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.

Verify that all LEDs next to the Mode button are green. If not, press and hold the Mode button to enter Express Setup mode.

If yes, change your PC or laptop settings to temporarily use DHCP before connecting it to 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.

If not, wait 30 seconds, reenter 10.0.0.1 in the browser, and press Enter.

If yes, reenter 10.0.0.1 in the browser, and press Enter.

Resetting the Switch

Caution Resetting the switch reboots the switch.

To reset the switch to the factory defaults:

Step 1 Press and hold the Mode button. The switch LEDs begin blinking after about 3 seconds.

Step 2 Continue holding down the Mode button. The LEDs stop blinking after 7 more seconds, and then the

switch restarts.

Step 3 The switch now operates like an unconfigured switch. You can enter the switch IP information by using

Express Setup as described in the “Running Express Setup” section on page 3.
