POE
This report considers the implementation of lightning surge protection for Power over Ethernet (PoE) powered sourcing equipment (PSE) applications. The necessity for implementing such protection will normally depend on the environment in which the PSE is intended to operate and the inherent isolation properties of the PSE. There are numerous compliance standards to consider when establishing the surge protection level of the PSE. These standards normally introduce a number of test conditions for various types of products ranging from main's power supplies to legacy telephone equipment. This report examines the various standards in an effort to relate the test conditions that would most likely be applicable to PoE PSE applications and provides suggestions for meeting the associated surge requirements.
