30.9 Telnet
I cannot telnet into the line card.
Table 30-9 Troubleshooting Telnet
STEPS CORRECTIVE ACTION
1 Make sure that a telnet session is not already operating. The line card only accepts one telnet
session at a time.
2 For the VLC1012, make sure telnet service is not disabled in menu 24.11.
Check that the IP address(es) in the Secured Client Sets menu (SMT menu 24.11.1) match the
client IP address(es). The line card immediately disconnects the telnet session if they do not match.
3 For the ALC1024 and SLC1024, check that the client IP address(es) match the configured secured
host IP address(es), refer to the secured host commands in the System Commands chapter. The
line card immediately disconnects the telnet session if they do not match.
4 Ping the line card from your computer.
If you are able to ping the line card but are still unable to telnet, contact the distributor.
If you cannot, check the cable, connections and IP configuration (see the IP Commands chapter).
5 If you are attempting to telnet from the DSL side of the line card, refer to section 30.2 to make sure
that you can transmit data to the line card.
6 If you are attempting to telnet from the Ethernet side of the line card, check the Ethernet cable and
connections between the EEC1020 and the Ethernet switch.
30.10 Emergency Console Port
The DSL line cards are equipped with a hidden RS-232 console port. It is intended for emergency recovery only,
e.g., you misconfigured the management VID, and not for day-to-day operation.
The console port is a 5-pin head with one pin broken off and located near the front panel to the left on the IES-2000
and to the top on the IES-3000.
To access the console port, you must remove the card on top (IES-2000) or to the right (IES-3000) of the card in
trouble. Connect the small, soft robber covered terminal of the enclosed RS-232 cable to the console port. Make
sure that the side with small windows where metal is visible is facing the center of the line card and line up the
triangle on the RS-232 cable with the 1 on the console port (this identifies pin 1). Connect one end of a regular RS-
232 cable to the female DB9 connector of the enclosed short cable and the other end to your computer.
You need a computer with a com port and terminal emulation software configured to the following parameters to
match the console port:
VT100 terminal emulation
9600 bps
None parity, 8 data bits, 1 stop bit
No flow control
