B.1. Accessing the Management Interface
This appendix is to help identify and solve the problems. If the switch is not working
correctly with your network, check the items as the following;
 Make sure the Power is ON (Check the Power LED).
 Check management cabling between the management station and the switch.
 Check the standard CAT.5 cable is used.
 Verify that the cable length does not exceed 100 meters.
 Check the LED indicators are working properly.
 Check the status of the cable attachment, or try a different cable.
 Try another port on the Switch.
 Turn off the power, and on again after a while and check if it resumes normally.

◆ 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.
