AT-FS708LE Installation Guide
To connect two 10 Mbps or 100 Mbps network
devices together that have dissimilar port
wiring configurations, such as an MDI to
MDI-X, you would use a straight-through
twisted pair cable. To connect two networks
devices that have the same wiring
configuration, such as MDI to MDI, you would
use a crossover cable.
The AT-FS708LE switch features automatic
MDI/MDI-X. Each RJ-45 port automatically
determines the configuration of the port on the
device to which it is connected and then
configures itself appropriately. For example, if
a port on a switch is connected to a port on a
bridge, which is typically wired as MDI, the
port on the switch automatically configures
itself as MDI-X. This feature allows you to use
either a crossover cable or a straight-through
cable when connecting a device to a twisted pair
port.
