• Be sure you have configured the agent with a valid IP address, subnet mask and default gateway.
• If you are trying to connect to the agent via the IP address for a tagged VLAN group, your
management station must include the appropriate tag in its transmitted frames.
• 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 or SSH, you may have exceeded the maximum number of
concurrent Telnet/SSH sessions permitted. Try connecting again at a later time.
