Appendix A
Troubleshooting
If you have trouble making a connection to the agent module, then
please refer to the following sections.
Console Connection
If you cannot access the on-board configuration program via a serial
port, be sure to have set the terminal emulator program to VT100
compatible, 8 data bits, 1 stop bit, no parity and 9600 bps. Also check
that the null-modem serial cable conforms to the pin-out
connections provided in Appendix B. If you forgot or lost the
password, contact Allied Telesyn Support for help.
In-Band Connection
You can access the management agent on the switch from anywhere
within the attached network using Telnet, a Web browser, or other
network management software. However, you must first configure
the switch with a valid IP address, subnet mask, and default gateway.
If you have trouble establishing a link to the management agent,
check to see if you have a valid network connection. Then verify that
you entered the correct IP address. Also, be sure the port through
which you are connecting to the switch has not been disabled. (See
Configuring Port Parameters on page 2-17.) If it has not been
disabled, then check the network cabling that runs between your
remote location and the switch.
Note
Up to four concurrent Telnet connections are supported.
