Electrical Specifications
This section describes the electrical specifications of the device.
3.1
Absolute Maximum Ratings
PoE performance is not guaranteed when it exceeds the recommended rating. Exposure to any
stress in the range between the recommended rating and the absolute maximum rating must be
limited to a short time. Exceeding these ratings might impact long-term operating reliability. The
following table lists the absolute maximum ratings.
