AI296 Local Menu System: Logging Into AI296

The following message appears when AI296 is configured to contact a TACACS+ server during authentication, but the contact attempt fails:

login: test Password:

Contacting TACACS+ server. Please wait. TACACS+ server(s) not responding.

Note: Five consecutive failed login attempts generate an SNMP trap and a log message saying that the login failed. Also, an entry appears in the log file with

text stating Warning: x consecutive failed login attempts where x is the number

of consecutive failed login attempts.

Using an Asynchronous Port for Login

Two tools are required for logging into AI296 using an asynchronous port:

zA PC with terminal emulation software such as HyperTerminal (included with Windows 95/98/2000/XP) or ProComm.

zTerminal cable with these specifications: null (RS232) cable with DB25 male connector for AI296 distribution panel connection and appropriate connector for your PC.

To log into AI296 using an asynchronous port:

1.Set the terminal emulation software to the following settings: z 9600 baud

z No parity

z Eight data bits z One stop bit

2.Power on AI296.

3.Connect a PC to port 1 on the DP232 distribution panel.

Note: Link 1 on AI296 is enabled and configured for login by default, which allows access through the link. AI296 may also be accessed through any asynchronous link that is enabled and configured for login.

4.Press ENTER. The login prompt appears.

5.Enter your user ID. The password prompt appears.

6.Enter your password. The destination menu appears. You are now logged into AI296.
