Short answer: Yes, Cat5e can do PoE (Power over Ethernet).

PoE (Power over Ethernet) allows cat5e patch leads and cat5e bulk cable to provide electric power as well as a data connection to devices such as switches, HDMI extenders, IP cameras, and routers.

There are three ways a cat5e cable will deliver PoE: Alternative A, Alternative B, and 4PPoE.

Alternative A transports power on the same wires as data for 10 and 100 Mbit/s ethernet variants.

Alternative B transports the power on separate pairs, meaning the data and power are separated into 2 different pairs, making troubleshooting easier.

4PPoE provides power on all four pairs of twisted cables. This enables the cable to provide power for higher power applications.
