Specifying a
Timeout Value
Specifying a timeout value is a way to prevent unauthorized individuals
from using the interface in the event you forget to exit the interface and
leave your management station unattended. By specifying a timeout
value, the program will end the session if it detects that there has been
no management activity after the timeout value has expired. The default
for the timeout value is 5 minutes.
To enter a new timeout value, perform the following procedure:
1. From the Main Menu, choose System configuration.
2. From the System Configuration Menu, select Omega Options.
The Omega Options Menu in Figure 27 on page 67 is displayed
3. From the Omega Options window, select the Timeout field and enter
a value from 0 (zero) to 65,535 (minutes). Press the Enter key.
Entering a value of 0 means there is no timeout. The interface will
not end any session. A session is ended only if you end the session
yourself. If you enter 0, you must always properly quit after a
management session in order not to block subsequent sessions
and software downloads to the multiplexer.
The new timeout value is immediately activated on the
multiplexer.
4. Return to the Main Menu.
Enabling or
Disabling the
Access Methods
As explained in Chapter 1, you can access the interface two ways either
locally through the RS-232 port or remotely using the Telnet application
protocol. You can disable either of the methods to enhance the security
of the multiplexer by preventing unauthorized individuals from making
changes to the unit’s configuration settings.
To enable or disable an access method, perform the following steps:
1. From the Main Menu, choose System configuration.
2. From the System Configuration Menu, select Omega Options.
3. From the Omega Options window, adjust the settings as required.
The interface access methods are described in the table below:
Access Method Description
Local Omega Enabled
Disable Local Omega These two selections allow you to control
whether the AT-S47 interface can be accessible
by connecting a terminal or PC to the RS-232
port on the management module. This is
referred to as accessing the program locally.
The default for this access method is enabled.
