Along with the description of the individual points, we will also give you information to

costs and the authorizations for the individual network users.

unauthorized persons.  The 
ELSA MicroLink Cable

'Management' configuration section on the 'Security' tab.  The password prompt can be
activated in a terminal or telnet session in the 
/Setup/Config-Module/
passw.prompt 
 menu.  In this case, the password itself is set with the command
passwd
