• 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 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.

factory settings.
