Select the ShareCenter from the list and click the Configuration button. This
will launch the computer's default web browser and direct it to the IP address
listed for the device. Make sure the browser is not configured to use a proxy
server.
Note: The computer used to access the ShareCenter web-based
configuration manager must be on the same subnet as the ShareCenter . If
your network is using a DHCP server and the computer receives IP settings
from DHCP server, the ShareCenterwill automatically be in the same subnet.
