Grounding the Industrial 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 Wiring the Redundant Power Inputs
The Industrial 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 Industrial Ethernet
Switch. Before powering the Industrial Ethernet Switch, please make sure that network
cables and power cables are securely connected.
ATTENTION
Before connecting the Industrial Ethernet Switch to the DC power
inputs, make sure the DC power source voltage is stable.
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.
