This evaluation board will work with Power Sourcing Equipment (PSE) that supplies the power
over the spare pair or the data pair with an auxiliary input as backup. It is suitable for use with the following products - Ag9312
The EVALAG9300 evaluation board can be powered using PoE through J2. PoE can either apply power over the spare pair on the CAT5e cable (pins 4 & 5 and pins 7 & 8) generally used by Midspan equipment. Or it can apply the power over the data pair (pins 1 & 2 and pins 3 & 6) via the centre tap of the data transformer (input), which is generally used by Endspan equipment.
The EVALAG9300 evaluation board is compatible with both of these methods and uses an IEEE802.3af compliant RJ45 connector (J2) with integrated magnetics (MJF11U2NNA8-VB110 from E & E Magnetic Products Ltd). If LED2 is illuminated then there is power on one of the PoE inputs (data pair or spare pair).
In addition to the PoE input, the EVALAG9300 evaluation board also has two AUX inputs. If PoE in not available, the PD module can be powered from a dc power supply via J4 (12Vdc to 48Vdc), or from an ac power supply via J1 (18Vac to 30Vac). If LED1 is illuminated then there is power on one of the AUX inputs.
