switch IP address. For example ping 192. 1 68. 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

Possible Causes and Resolutions
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 for the switch. You can
determine the status of how the switch obtained the current IP address
by observing the system LED. You can determine the current IP
address of the switch through the console port interface by using the
CLI, or from your network administrator.
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.
