No need to use power adapter when the device work with POE-1200/2400.
Once the POE-1200/2400 power off, you can use the power adapter to support power to your device. The network connection pass through POE-1200/2400 is still available to backend switch.
You can use a PoE splitter, such as PLANET POE-150S, to work as a power transformer between POE-1200/2400 and the Ethernet device. Three types of POE-150S are available for different voltage, 5VDC, 9VDC, and 12VDC.
For switch function, the three switches provide with 24 10/100Mbps TP ports. FGSW-2402PVS has 2 open slots for 10/100Base-TX, 1000Base-T and 100Base-FX, 1000Base-SX/LX fiber-optic interface. FGSW-2620PVS and FGSW-2612PVS have 2 fixed 10/100/1000Base-T RJ-45, SFP (mini GBIC), either TP or SFP.
For PoE function, FGSW-2620PVS and FGSW-2402PVS support 24 Power over Ethernet injector TP ports, that is, all the 24 10/100Mbps TP ports can supply 48VDC power to IEEE802.3af compliant Ethernet devices. The FGSW-2612PVS support only 12 Power over Ethernet TP ports. Only first 12 TP port support PoE function.
No, the device can be powered directly by the PoE Switch. Use a Ethernet CAT5 cable connect to the 802.3af built-in port and any (the first 12, for FGSW-2612PVS) of the 10/100Mbps TP port. The device can automatically be powered on.
You can ignore the power adapter when use PoE switch to power on your device.
Yes.
The PoE switches are provided with PoE control and power usage status functions in both Web and Console management interface. You can use the control function to power on/off the device and view the power usage for each devices connected to the PoE switch.
The following PLANET products are built-in IEEE802.3af splitter and can be powered by FSD-804P: FSD-803PE, FSD-504PE, VIP-103PT, VIP-153PT, ICA-100PE, WAP-4060PE, WSG-402 and POE-150S. Of course, third party products that fully complied with IEEE802.3af can be powered by FSD-804P or FSD-804PS as well.
