1. General Information
The PoE Switch PSE-SW8G44D0++ provides seven 10M/100M/1000M TX ports with PoE PSE
function plus one 10M/100M/1000M TX up-link port. It allows power souring equipment (PSE) to
be powered from DC source and delivers power to any PoE powered device (PD) which is
compliant with IEEE802.3af/at standards.
In the LT PoE++ model, the PoE PSE delivers power up to 70W/port to a PD. The LTPoE++ is
Linear Technology Corporation’s specification. This specification provides detection and
classification extensions to existing IEEE PoE protocols. It is backward compatible with IEEE
802.3af and 802.3at.
2. Hardware Description
