D1812 – 12 ports – front plate
D1816 – 16 ports – front plate
3.1 Power Cable Connection
The AC power cable is connected to the switched IEC power inlet located at the rear of the Dycon
PoE Midspan unit. The power cord must be plugged into an earthed 230V nominal power outlet,
with a minimum current rating of 10A.
3.2 Ethernet Connection
Category 5e cables using 10BASE-T and 100BASE-T Ethernet 8P8C modular connections can be
used with this PoE midspan power injector. The unit can provide nominal maximum of ~34W
(measured at the midspan output depending on the class of the powered device) at ~54V (~630mA)
per port and is IEEE 802-at complaint and backwards compatible with IEEE 802-af.
The Ethernet ports are organised in multiples of 4 pairs of 8P8C modular connectors (RJ45).
Depending on the model a maximum of 16 ports are available. The Ethernet data input (from an
Ethernet switch etc.) is connected to the lower data input connectors and the output with injected
power is connected to the corresponding upper data and power output connector.
1. Check the unit is plugged in and switched on at the rear of the unit. The yellow standby
LEDs on the front modular connectors will be illuminated indicating that power is available.
2. Connect the Ethernet data cables to the bottom row data inputs.
3. Connect the cable to the powered device to the corresponding upper data and power output
modular connector.
4. Wait for a few seconds and check that the Green LED illuminates indicating that a valid
power signature has been detected from the powered device and output power has been
successfully applied.

Notes:
Each 4 pairs of modular connectors are powered by an individual power supply. Should an
individual power supply fault develop or the power supply temporarily close down after a thermal
overload, only four out a potential 16 ports will be affected.
