SETTING THE MDI/MDI-X SWITCH
Using the MDI/MDI-X switch, the Megabit Modem 410F and 420F can communicate with a
device on the LAN that is either MDI or MDI-X without having to change the cable
(a straight-through cable is supplied with the installation kit).
Set the switch for the 10/100BASE-T port to:
• MDI-X when you are connecting to a device with an MDI port such as a PC with an
Ethernet NIC
• MDI when you are connecting to a device with an MDI-X port such as a hub, repeater,
bridge, or router
