switch is turned on.
2.Verify if your cable is sufficient for your network requirements.
A 1000 Mbps network (1000BaseTx) should use cables labeled

another host in the
same network
1.Check the Ethernet cabling is good and the LED is green.
2.If the port LED is amber, check if this port is disabled. You
may experience a disconnected network in a short period
(around 1 minute) if you just turned on the STP.

web configuration
pages.

The factory default IP for the switch is 192.168.1.1.
2.Verify your network setup in your PC for this information.
If your PC does not have a valid route to access the switch,
change the switch IP to an appropriate IP that your PC can
access.
3.Ping “switch IP” from the PC, if it still fails, repeat step 2.
4.If ping is successful but the web configuration still fails,
connecting PC through the console port by a RS232 or USB,
check if any filter rule or static MAC address is set to block the
WEB traffics.
