The computer is unable to communicate with the product
Test network communication by pinging the network.
a. Open a command-line prompt on your computer. For Windows, click Start, click Run, and
then type cmd.
b. Type ping followed by the IP address for your product.
For Mac OS X, open the Network Utility, and then supply the IP address in the correct field in
the Ping pane.
If the window displays round-trip times, the network is working.
If the ping command failed, verify that the network hubs are on, and then verify that the network
settings, the product, and the computer are all configured for the same network.
