Link speed and duplex settings
NOTE: This information applies only to Ethernet networks. It does not apply to wireless networks.
The link speed and communication mode of the print server must match the network hub. For most
situations, leave the product in automatic mode. Incorrect changes to the link speed and duplex settings
might prevent the product from communicating with other network devices. If you need to make
changes, use the product control panel.
NOTE: The setting must match with the network product to which you are connecting (a network hub,
switch, gateway, router, or computer).
NOTE: Making changes to these settings causes the product to turn off and then on. Make changes
only when the product is idle.
