Note: If a port operates at 100 Mbps, Category 5 cabling must be used. Category 3
cabling does not meet 100 Mbps specifications. For 10 Mbps operations only, Category3
or Category 5 cabling can be used.
Note: The RJ45 ports support Category 5 UTP cabling with an impedance between 85
and 111 ohms for 100 Mbps operation.
The 2G4072-52 is capable of operating at either 10 or 100 Mbps. It automatically senses
the speed of the connected device and adjusts its speed accordingly.
Note: The 48 ports of the device support Category 5 UTP cabling with an impedance
between 85 and 111 ohms for 100 and 1000 Mbps operation.
Ports 1 through 48 can operate at either 10, 100, or 1000 Mbps. The device automatically
senses the speed of the connected device and adjusts its speed accordingly.
