3.4 Indications
The following sections provide general information regarding unit indications.
3.4.1.1 LED Indication
See Figure 5.
D14 is the Power_GOOD indication LED, a PD70210 device output signal indicating the device isolation switch is
operated. In all operating state this flag is lit.
D12 is the AT_FLAG indication LED, a PD70210 device output signal indicating the device has detected a 2 finger
class event from the PSE side in the class stage. The flag will be operative at 3, 4, and 6 fingers detection as well.
D10 is the 4P_AT indication LED, a PD70210 device output signal indicating the device has detected a 4 finger
class event from the PSE side in the class stage, or a 2 finger class event from the PSE side in the class stage,
and SUPP_Sa and SUPP_Sb are both High.
The flag will be operative at 6 fingers detection as well.
D11 is the HD_FLAG indication LED, a PD70210 device output signal indicating the device has detected a 3 finger
class event from the PSE side in the class stage.
The flag will be operative at 6 fingers detection as well.
D9 is the 4P_HD indication LED, a PD70210 device output signal indicating the device has detected a 6 finger
class event from the PSE side in the class stage.

5 Installation
5.1 Preliminary Considerations and Safety Precautions
Verify board's power supply is turned off before all peripheral devices are connected.
Note: In maximum power at the output, some of the devices may reach high temperatures (still less than 70
degrees). Pay attention while testing these devices.
5.2 Initial Configuration
Note: Prior to starting any operation, it is important to verify that the Evaluation Board is setup as shown in Figure
6.
1. Connect load to main board (J5), while it is turned Off.
Notice: To comply with IEEE802.3AT standard, the load should be set only after the PSE is On.
The indication for PSE On is PGOOD led lit.
2. Connect a Cat5 cable from PSE to Evaluation Board (J1).
3. Turn On the Load.
