servers on your network.

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 selecting Start > Run and enter cmd.
STEP 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
