◦ All cable connections to the computer and the device are secure.
◦ The network is operational and the network hub is turned on.
◦ All applications, including virus protection programs, spyware protection
programs, and firewalls, are closed or disabled for computers running Windows.
◦ Make sure the device is installed on the same subnet as the computers that will
be using the device.

configuration page and enter the IP address manually in the installation program.

firewall) by doing so.
