12. vi is a small editor, loosely based on old WordStar. If the display is incorrect, type ‘ctrl – R’. If vi
refuses to start, your telnet client is either not setup properly or is a bad telnet client (Windows
HyperTerminal does work, if setup correctly). Type ‘ctrl – KX’ to exit the editor, and ‘ctrl – KH
for a help screen.
13. When finished changing parameters. You can either wait 10 seconds and then turn the power
off or type ‘reboot’ to restart the 2411.
14. If you have changed the IP address, you will need to use the new IP address with subsequent
telnet sessions.
III. Setting up the 2411 via serial terminal: (should be used if there is a network conflict, or you
have forgotten the target IP address, or any other network problem):
1. Connect one end of a serial (crossover / null modem) cable to the 2411 com1 port
(a DB-9 to 10 pin header cable is supplied) and connect the other end of the serial cable to
either a dumb terminal or a workstation with terminal emulation.
Connect the DB-9-to-10 pin header cable mentioned above to the 301 CPU board in the stack
via a header connector located next to the RJ-45 network jack. When installed, the red wire on
the cable must point away from the RJ-45 jack.
The terminal settings must be 9600 baud, no parity, 8 bits, 1 stop, software flow control
(xon/xoff). Ideally the terminal type should be VT100 but ANSI will work.
HINT: Most Windows based workstations have HyperTerminal installed (under
Programs/Accessories/Communications). To setup, start HyperTerminal, go to File ->
Properties -> Configure and set the bits per second to 9600, bits to 8, stop bits to 1, parity to
none, and flow control to Xon/Xoff. Press OK and set the com port.
2. Start the terminal.
3. Connect +12V to +24V DC to the Power Supply board, Model 207 in the stack. Turn on the
power.
4. Within 5 seconds or so you should be seeing the console output on the terminal. The boot
process will be finished after about 20 seconds.
5. At ‘2411 login’ prompt, type ‘root’ and then press
6. At ‘Password’ prompt, type factory password and press
7. You should now see “2411SYS:~ #”. If you mistyped something and the login failed, just press
8. Type ‘cd /usr/etc’ to take you to the directory containing the user modifiable configuration files.
9. Type ‘ls’ and a listing of the files will be shown.
10. Now the IP address can be changed. At the shell prompt type
‘netconfig eth0 -i your_ip -m your_netmask’ and then press
for example, ‘netconfig eth0 -i 192.168.1.23 -m 255.255.255.0’
11. Another way to modify the IP address, is to edit the ‘system.config’ file by typing “vi
/usr/etc/system.config”.
12. vi is a small editor, loosely based on old WordStar. If the display is incorrect, type ‘ctrl – R’. If vi
refuses to start or doesn’t behave properly, your terminal is not setup properly (Windows
HyperTerminal does work, if setup correctly). Type ‘ctrl – KX’ to exit the editor, and ‘ctrl – KH
for a help screen.
