Chapter 4 Seven-port autosensing switch specifications 53

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.
