2.11 Making PoE PSE Connections (SF71060MP)
This section describes how to make a connection between an SF71060MP PSE port and a PoE PD device.
To make a PoE connection, the following check points should be noted:
1. For safety reasons, the connected PoE PD (Powered Device) must be a IEEE 802.3at or IEEE
802.3af-compliant device. Incompliant devices are not supported by the SF71060MP.
2. The Cat.5 cables used for the connections must be 4-pair cables. The power is sent over the spare pairs (4,5)
(7,8) of the cable. The maximum distance supported is 100 meters.
3. The power voltage supplied to the switch must be within the range as specified in
section 2.5
to make the
PoE function work.
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.
The figure below illustrates a connection example:
