MDI/MDI-X autosensing capability

When you plug an Ethernet cable into a port, the switch autosenses whether the
cable is MDI-X (normal, or straight-through) or MDI (uplink, or crossover). This
feature enables you to connect the Instant Internet unit to another Ethernet
connection regardless of whether you are using a straight-through cable or a
crossover cable.
Note: Observe standard networking guidelines when you use the
seven-port switch to install or connect an Instant Internet 400-S unit to
additional devices.
