Note: When using the fixed ports on the switch for 100 Mbps operation use Category 5
UTP cabling with an impedance between 85 and 111 ohms for 100 Mbps operation.
The fixed switch ports are capable of operating at 10, 100, or 1000 Mbps. This is
accomplished by the switch when Auto-Negotiation is enabled. This enables the switch to
automatically sense the transmission speed of the other device and adjust for the speed
accordingly.
