Asynchronous Port Switches User s Guide Configuration 5 3 1 The Supervisor Password The Supervisor Password allows access to higher level APS configuration commands which administrators can employ to select communication parameters assign port access rights and perform other system management tasks After the Supervisor Password has been defined via the System Parameters menu the APS will display a password prompt whenever you attempt to access the command mode If the correct Supervisor Password is entered the APS command mode then starts up in Supervisor Mode Supervisor Level commands are summarized in Section 9 3 of this User s Guide Notes e If the Supervisor Password is not defined then Supervisor Level commands will be available to all ports and port access and configuration functions will not be password protected e If you wish to restrict user ports from changing APS configuration parameters or connecting to restricted ports the Supervisor Password must be defined e When the Supervisor Password is defined the APS will display a password prompt when you attempt to access the command mode Any RS232 port that has not been assigned a Port Password can then only be accessed using the Supervisor Password e When defining a Supervisor Password it is strongly recommended that you record the password for future use If you forget or lose your Supervisor Password you will not be able to access Supervisor Level Comma
