Grounding the Managed Industrial PoE Ethernet Switch
Grounding helps to limit the effects of noise due to electromagnetic interference (EMI).
Be sure to install the ground connection from the ground screw to the grounding
surface before connecting devices.

2.4 Powering the Managed Industrial PoE Ethernet
Switch
The Managed Industrial PoE Ethernet Switch can be used with DC power 48-54 VDC
with 2 terminal blocks. The terminal blocks are located on the upper panel of the
Managed Industrial PoE Ethernet Switch. Before powering the Managed Industrial PoE
Ethernet Switch, please make sure that network cables and power cables are securely
connected.
ATTENTION
Before connecting the Managed Industrial PoE Ethernet Switch to
the DC power inputs, make sure the DC power source voltage is
stable.
Wiring the terminal blocks
PWR1 and PWR2 power supply
are two pairs of contacts on the terminal block
connectors for power redundancy purpose. The redundant power supply will take over
seamlessly when one power source is down to protect your device or network from the
loss of power. When you use only one power supply (no redundant power is available),
the LED Power/Port Status will flash in orange to alert the user.
