Action
• Be sure you have configured the agent with a valid IP address, subnet
mask and default gateway.
• Check that you have a valid network connection to the switch and that
the port you are using has not been disabled.
• Check network cabling between the management station and the
switch.
• If you cannot connect using Telnet, there may already be another active
session. Try connecting again at a later time.
• Be sure you have set the terminal emulator program to VT100
compatible, 8 data bits, 1 stop bit, no parity, and 9600 bps.
• Check that the null-modem serial cable conforms to the pin-out
connections provided in Appendix B.
• Contact Alcatel's technical support for help.
