To enable managed mode, follow these steps:

• Attach power cord to the switch
• Wait for the Managed Mode LED to stop flashing and turns off.
• Press the Managed Mode pin-hole button on the front of the switch. The switch will power cycle and the Managed Mode LED will stay lit.
• The switch is now in Managed Mode.

To configure the switch while in Managed Mode, follow these steps:

• First, collect the following information
  • IP address for the switch
  • Netmask for the network
  • IP address for the gateway.
• From a computer attached to the switch, open a web browser.
• If the switch has never before been configured, enter the following IP in the browser's address bar: 192.168.2.1
• A login screen should appear. Enter admin for the username and keep the password field blank.
• Press the OK button to login.

Jumbo Frames:

• In order to use jumbo frames up to 9K, the switch must first be put into Managed Mode.
• After Managed Mode has been turned on, log into the switch via the web interface.
• Use the navigation box on the left side of the window. Click on Jumbo Frames
• Change Disabled to Enabled. The switch will then power cycle.
• Log out, and test.
