1 Introduction In troduc tion This chapter provides an overview of Power over Ethernet (PoE) and a list of reasons why a user might want to implement PoE in their environment. It discusses how PoE transmits power over twisted pair cable and the capabilities of the devices used to provide PoE. Overv...
Page 9 - PoE Capabilities of the Products
Introduction Overview Power Through the Cable A standard CAT5 Ethernet cable has four twisted pairs, but only two of these pairs are used for 10Base-T and 100Base-TX data. The specification allows two options for using these cables for power: ■ The spare pairs are used. The pair on pins 4 and 5 are ...
