Chapter 3: Installing the Megabit Modem 410F and 420F

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
