NET
The power supply should be connected to the Positive and Signal ground inputs, ensuring
the polarity is correct.
POWER SUPPLY CHOICE & PoE LOADING
The choice of power supply, in terms of its power rating, depends on the intended loading of
the four PoE ports.
If the intention is to supply four Class 1 devices (for example RIO or BPS) then a 24W (48V
@0.5A) supply will suffice.
If, however, the intention is to supply four Class 2 devices (for example MSC) then a 48W (48V
@1A) supply will be required.
Multiple NETs may be powered by a single power supply provided its rating is increased
accordingly.
GROUNDING
The NET is designed to be mounted on a grounded (earthed) DIN-rail and a dedicated Chassis
ground (earth) terminal is also provided which should be connected to a suitable earth.
STATUS LEDS
The ETC logo will illuminate when power is applied to the NET. The red LEDs on the top of
the NET indicate the unit's status:
Active: Indicates that the unit is functional.
Ethernet: Illuminates when the link has been established and toggles off to indicate data.
Port 1-4: Illuminates when the link has been established and toggles off to indicate data.
PoE: Indicates that one or more of the ports is supplying PoE power.
Error: Flashes to indicate an error condition.
