Power over Ethernet allows devices to be powered over 4-pair category cables.
The IEEE standards 802.3.af and IEEE 802.3.at has ratified first two types of PoE.
As well known, not all cables are constructed to be able to safely support the high power in the installation configurations.
What type of cable is required for PoE?
Ethernet cable that meets CAT5e (or better) standards consists of four twisted pairs of cable, and PoE sends power over these pairs to PoE-enabled devices.
Does cat6 cable support PoE?
802.3at works over Cat 5 cable or higher. And Cat6 cable is ok for PoE applications. Any Cat6 will do, the PoE specification was designed already for standarised Cat5(x) & Cat6(x) cables
Are all 8 wires used in Ethernet?
Ethernet Cat 5 cables have eight wires (four pairs), but under 10BaseT and 100BaseT standards (10 Mbps and 100 Mbps, respectively) only four (two pairs) of these wires are actually used. One pair is used for transmitting data and the other pair is used for receiving data.
Can you plug non PoE into Poe?
Yes it is safe to have PoE and non-PoE. on the same switch. The power will only engage if the device has request.
