connector, P5
The PoE pass-through connector, P5, mates with the P20 header on the development
board. This PoE pass-through feature passes PoE power connections from the
Ethernet signal cable to the user’s equipment through P5. The PoE feature provides
a power source for compliant “powered” equipment, and is nominally 48VDC with a
possible 30–57VDC 13 W maximum range.

PoE support If you are planning to add PoE support to your product, see the most recent revision
of the IEEE 802.3af specification available at http://www.ieee802.org/3/af/. The
document provides detailed information about the standard and its proper
implementation.
LED Description
Green Network link: On indicates an active network link; Off indicates that no network link is
present.
Yellow Network activity: Flashing when network traffic detected; Off when no network traffic
detected.
