C Disconnect and AC Disconnect both of which provide the same functionality the PSE shutdowns power to a disconnected port within 300 to 400ms The upper boundary is a physical human limit for disconnecting one PD and reconnecting another DC 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 216 GE DS 82 and 82 PoE Ethernet Managed Switch User Manual Chapter 9 Troubleshooting This chapter contains information to help you solve common problems If the Ethernet Switch is not functioning properly make sure the Ethernet Switch was set up according to the instruct
