.
S
TEP
2
At the
Command
window prompt, enter
ping
and the switch IP
address. For example,
ping 192.168.1.254
(the default static IP
address of the 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 that they are firmly plugged into the switch
and your computer.
Bad Console port connection:
Check the console cable connectors to make sure that they are firmly
plugged into the switch and your computer. Make sure that the console
port utility is configured with the correct parameters.
Wrong IP address:
Make sure that you are using the correct IP address of the switch. You
can determine the current IP address of the switch from the CLI
through the console port, or from your network administrator. The
System LED provides an indication of where the switch received the IP
address (See
for details.) Make sure that no other device is
using the same IP address as the switch.
