Security Settings (Option 6)

You can change security settings by means of Telnet or serial connections only, not on the Web
Manager. We recommend that you set security over the dedicated network or over the serial
setup to prevent eavesdropping.
Caution: Disabling both Telnet Setup and Port 77FE will prevent users from
accessing Setup Mode from the network. Disabling Port 77FE also disables the
Web Manager and DeviceInstaller from configuring the device.
Select 6 to configure security settings.
