Every 100BASE-TX port supports an Auto-Negotiation function that automatically senses for the fastest possible speed the attached device is capable of (10Mbps - 200Mbps), then automatically sets the Switch to operate at that speed. No complicated configuration is necessary when setting up either model. Users only need to attach network cables, then power "On". When they are operational, a complete range of front panel LEDs provides a real time reference point for viewing operational status.
