5.1 Preliminary Considerations and Safety Precautions
If using an external supply in place of a PSE, verify the external power supply is turned
“off”
before all peripheral devices are connected. Insure the external supply is connected to the
RJ45 input (J1) per Table 3.
5.2 Initial Configuration
Note
: It is important to verify evaluation board is setup as shown in Figure 6 prior to starting any operation.
1. Connect load to evaluation board (J3 -1 (+) & J3
– 2 (-), or TP17 (+) & TP16 (-)).
2. Connect a Cat5 cable from PSE to Evaluation Board (J1), or a 48V Wall Adapter to Evaluation Board (J2).
Note: Wall Adapter will override power from PSE.
