Troubleshoot Your Connection

If you cannot access your switch from the web-based interface, the switch
might not be reachable from your computer. You can test network
connections by using the ping command. The following section shows
how to use "ping" in a Windows environment:
Open a command window by using Start > Run and enter cmd.

IP address. For example ping 192. 1 68. 1 .254 (the default IP address
of the smart switch).
If you can reach the switch, you should get a reply similar to the
following:
Pinging 192.168.1.254 with 32 bytes of data:
Reply from 192.168.1.254: bytes=32 time<1ms TTL=128
If you cannot reach the switch, you should get a reply similar to the
following:
Pinging 192.168.1.254 with 32 bytes of data:
Request timed out.
Possible Causes and Resolutions
No Power:
Power up the switch and your computer if they are turned off.
Bad Ethernet connection:
Check the LEDs for proper indications. Check the connectors of the
Ethernet cable to ensure they are firmly plugged into the switch and
your computer.
Wrong or conflicting IP address:
Make sure that you are using the correct IP address of the switch. You
can verify the current IP address of the switch with your network
administrator. The System LED provides an indication of where the
switch received the IP address, see Section 4 for details.
Make sure that no other device is using the same IP address as the
switch.
No IP route:
If the switch and your computer are in different IP subnets, you need
one or more routers to route the packets between the two subnets.
