The pins X2.1 and X2.2 are used as an alternative power supply input. The applied voltage
is 24 V DC. Pins X2.15 and X2.16 are directly connected to X2.1 and X2.2 respectively.
These can be used as power supply outputs to supply e.g. sensors, etc. The power of these
pins is limited by the power of the power supply used or the PoE power limit.
