Note: 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 the setup menu from the network. Disabling Port 77FE

also disables the Web from configuring the device.

Select 7 to configure security settings.
