Uplink and Power Connections

The AP3912i uses PoE (Power over Ethernet) as follows:

Power Sources

Power Source	Description
LAN 1 uplink PoE	LAN 1 may be connected using an 802.3at or 802.3af switch port
PoE 802.3at	Power is enabled on the PSE Client port and the PSE LED is green.
PoE 802.3af	Power is disabled on the PSE Client port and the LED is off (not green).

The AP has three client ports (P1, P2, and P/3/PSE). These client ports let users connect to wired clients, such as laptops and printers, to the network. The PSE power of P3 is enabled only if LAN 1 is powered using 802.3at.

When the PSE is enabled., 802.3af PoE devices, such as IP cameras, can be powered from P3.

The pass-through port (blue connector) allows direct connection to a second switch port. On the pass-through port, power and connection attributes (such as speed and duplex) of devices are dictated by the characteristics of the corresponding switch model and by the port that the backend pass-through port is connected to.

Note

LAN connectors with shrouds will not fit into the ports. Remove the shroud or use an optional jumper cable.

Ports and Reset Button Location

The Reset button is located to the right of the power connections. (See the arrow in the previous figure.) Insert a straightened paperclip into the hole and depress the switch.
