2.5.2 PoE Port Interfaces

The TPS23881B1 device must be configured through the host to become operational if the device is not configured to autonomous mode (described in section 2.4). This EVM provides two ways to control the TPS23881B1: TPS238x EVM GUI (with USB2ANY) and MSP-EXP430FR5969 LaunchPad.
