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 managed switch IP address. For example ping 192.168.1.254 (the default static IP address of the managed 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.

Bad Console port connection:

Check the console cable connectors to make sure they are firmly plugged into the switch and your computer. Make sure the console port utility is configured with the correct parameters.

Wrong IP address:

Make sure you are using the correct IP address of the switch. You can determine the status of where you received the current IP address of the switch from the system LED. You can determine the current IP address of the switch from the menu CLI through the console port interface, or from your network administrator.

Make sure that no other device is using the same IP address as the switch.
