Cable Type
Standard TIA/EIA 568-
B-compliant Category 3
shielded or unshielded
cabling with 100 ohm
impedance and a
frequency of 16 MHz.
Standard TIA/EIA 568-
A-compliant Category 5
shielded or unshielded
cabling with 100 ohm
impedance and a
frequency of 100 MHz.
Standard TIA/EIA 568-
B-compliant Enhanced
Category 5 (Cat 5e)
shielded or unshielded
cabling with 100 ohm
impedance and a
frequency of 100 MHz.
Standard TIA/EIA 568-
B-compliant Category 6
or 6a shielded cabling.
The PoE and PoE+ standards define five powered device classes. The
classes are defined by the power requirements of the powered devices.
The classes are shown in Table 4 on page 27. The AT-IE300-12GP
Switch supports all five classes.
