*Power wiring
The PoE switch PSE-S+ use LT PoE++ chipset, for PoE operation, make sure your
power supply may offer at least 125W for 7x 802.3af PoE ports, or 250W for 7x 802.3at PoE ports,
or 650W for 7x LTPoE++ ports. The input voltage must be in the range of 44 to 57VDC if using for
802.3af operation. The input voltage must be in the range of 50 to 57VDC if using for 802.3at
operation. The input voltage must be in the range of 55 to 57VDC if using for LTPoE++ operation.
If the PoE switch is not powered with the above designated input voltage, it will only function as an
Ethernet switch without PoE output.
(option: you may use 2x MS-180-56 (
56VDC/3.21A) or 2x MS-270-56 (56V/4.82A) as the DC source)
