Symptom Action
Cannot connect using
Telnet, Web browser,
or SNMP software
• Be sure the switch is powered up.
• Check network cabling between the management station and the
switch.
• Check that you have a valid network connection to the
SMC6824MPE switch and that the port you are using has not been
disabled.
• Be sure you have configured the VLAN interface through which
the management station is connected with a valid IP address,
subnet mask and default gateway.
• Be sure the management station has an IP address in the same
subnet as the switch’s IP interface to which it is connected.
• If you are trying to connect to the switch via the IP address for a
tagged VLAN group, your management station, and the ports
connecting intermediate switches in the network, must be
configured with the appropriate tag.
• If you cannot connect using Telnet, you may have exceeded the
maximum number of concurrent Telnet/SSH sessions permitted.
Try connecting again at a later time.
