Chapter 3 Hardware Installation
3.1Hardware installation
3.1.1Unpack switch and check the accessory with packing content list
3.1.2 Mount the switch on desired position. For the best ventilation, it is
suggested to mount the switch on metallic surface.
3.1.3 Connect the M23/M12 connector of power input. The PoE power
supply for IPES-5408T series is connected via a 5-pole M23 female
connector while IES-5408T is with a 5-pole M12 female connector.
Voltage of Power Input
For IPES-5408T series, the voltage of power input should use
48VDC to feed power IEEE 802.3af standardized devices or
54VDC for IEEE 802.3at standardized ones.
For IPES-5408T-12V series, the power input voltage can be from
9.2V to 56VDC to feed power on both the 802.3af and 802.3at
standardized devices.
With IPES-5408T-72V series, the power input voltage can be from
72V to feed power on both 802.3af/at standardized devices. IES-
5408T series can accept power input ranging from
9.2V~72V(12V~72V) to be powered.
Please make sure that the external power supply unit you use to
provide the PoE voltage meet the following criteria:
The output voltage of power supply must exceed 48VDC for 802.3af
and 53VDC for 802.3at operation(with IPES-5408T-72V, only 72VDC
can power both the 802.3af and 802.3at PD.)
The power consumption can satisfy the total power request from all
PD devices required.
