2.9 Making PoE PSE Connections (KGS-2461-HP)
This section describes how to make a connection between a PSE port and a PoE Powered D device (PD). All
copper ports are equipped with PoE PSE function. The ports are enabled to deliver power together with
network signal to a connected powered device via Cat.5 cable. To make a PoE connection, the connected PoE
PD must be a IEEE 802.3at or IEEE 802.3af-compliant device for safety reason. Incompliant devices are not
supported by the PoE switch model.

The PSE ports are equipped with the following capabilities:
1. Detection for an IEEE 802.3af /802.3at compliant PD.
2. No power is supplied to a device which is classified non-IEEE 802.3af compliant PD.
3. No power is supplied when no connection exists on the port.
4. The power is cut off immediately from powering condition when a disconnection occurs.
5. The power is cut off immediately from powering condition when overload occurs.
6. The power is cut off immediately from powering condition when over-current occurs.
7. The power is cut off immediately from powering condition when short circuit condition occurs.
