8 Cisco 200 Series Smart Switches

Troubleshoot Your Connection

If you cannot access your switch from the web-based interface, the switch

may not be reachable from your computer. You can test network

connections by using ping on a computer running Windows:

STEP 1 Open a command window by using Start > Run and enter cmd.

STEP 2 At the Command window prompt enter ping and the smart switch

IP address. For example ping 192.168.1.254 (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.
