C Disconnect DC Disconnect detection involves measurement of current Naturally a disconnected PD stops consuming current which can be inspected by the PSE The PSE must therefore disconnect power within 300 to 400 ms from the current flow stop The lower time boundary is important to prevent shutdown due to random fluctuations AC Disconnect This method is based on the fact that when a valid PD is connected to a port the AC impedance measured on its terminals is significantly lower than in the case of an open port disconnected PD AC Disconnect detection involves the induction of low AC signal in addition to the 48 VDC operating voltage The returned AC signal amplitude is monitored by the PSE at the port terminals During normal operation the PD s relatively low impedance lowers the returned AC signal while a sudden disconnection of this PD will cause a surge to the full AC signal level and will indicate PD disconnection 170 GE DSH 73 DSH 82 and DSH 82 PoE User Manual Appendix A RJ 45 Pin Assignment Switch s RJ 45 Pin Assignments 1000Mbps 1000Base T Contact MDI MDI X 1 BI_DA BI_DB 2 BI_DA BI_DB 3 BI_DB BI_DA 4 BI_DC BI_DD 5 BI_DC BI_DD 6 BI_DB BI_DA 7 BI_DD BI_DC 8 BI_DD BI_DC Implicit implementation of the crossover function within a twisted pair cable or at a wiring panel while not expressly forbidden is beyond the scope of this standard GE DSH 73 DS
