How to Configure a Cisco 3750 (express config)

  • 1

    Disconnect any computers or other devices from the switch and unplug the switch’s power supply.

  • 2

    Reconnect the switch’s power supply to a grounded AC outlet. The switch’s indicator lights will flash while it performs a self-test. Wait until the “SYST” light on the switch turns solid green, indicating the test is complete. This can take several minutes.

  • 3

    Hold the “Mode” button for three seconds, until the LEDs left of the “Mode” button turn green, then release it. The “Mode” button is in the bottom-left corner of the switch.

  • 4

    Connect an Ethernet cable to any of the switch’s Ethernet ports and plug the other end into your computer. Check that the lights on the switch and your computer’s Ethernet card are green and wait 30 seconds.

  • 5

    Open a web browser on your PC and enter “10.0.0.1” into the address bar. This brings you to the Cisco 3750’s Express Setup page.

  • 6

    Enter “10.0.0.1” into the “IP Address” field of the “Basic Settings” tab. If you are connecting the switch to the Internet through a modem or router, enter the modem or router’s IP address in the “Default Gateway” field. The modem or router’s IP address should be in its manual.

  • 7

    Enter a password in the “Switch Password” field, and repeat it in the “Confirm Switch Password” field. This password will be required to access the switch’s configuration page in the future.

  • 8

    Enter a name for the switch and fill in the date, time and time zone information under “Optional Settings” if you wish. Basic configuration is now complete, though you may wish to alter some advanced settings as well.

  • 9

    Click on the “Advanced Settings” tab.

  • 10

    Click “Enable” beside “Telnet Access” if you plan to use Telnet to manage the switch using a command-line interface. Enter a password into the “Telnet Password” and “Confirm Telnet Password” fields as well.

  • 11

    Click “Enable” beside “SNMP” to enable Simple Network Management Protocol (SNMP). This option should only be enabled if you plan to manage the switch using CiscoWorks 2000 or another SNMP system. You must enter the “Read Community,” “Write Community,” “System Contact” and “System Location” information if you enable SNMP.

  • 12

    Check the “Enable IPv6” box if you wish to enable it. IPv6 features better support for mobile devices like cell phones and PDAs, simplified address auto-configuration, and improved data encryption, compared to IPv4. Enabling IPv6 will restart your switch when exiting Express Setup.

  • 13

    Click “Submit” to save and apply your settings. Your Cisco 3750 should now be configured and ready to install in your service network.
