Action
•
Be sure to 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, you may have
exceeded the maximum number of concurrent Telnet
sessions permitted. Try connecting again at a later time.
•
Be sure to have set the terminal emulator program to
VT100 compatible, 8 data bits, 1 stop bit, no parity and
19200 bps.
•
If the switch is configured for Auto (baud rate detection),
the terminal emulator program must be set at
2400~19200 baud, 8 data bits, 1 stop bit, no parity, and
flow control set to none. Also, you must first press the
Enter key once to set the data rate and initialize the
connection.
•
Check that the null-modem serial cable conforms to the
pin-out connections provided in Appendix B.
