Power Redundancy & UPS Input
The switch offers dual power redundancy, i.e., AC & DC input. There are two power inputs, as shown below
diagram:
When the AC input is connected, the AC is the main power input to the switch. To enable the power redundancy,
you connect the DC power to the 4-Pin Terminal with a 48V DC and up to 57V DC power source. After the DC is
connected, the power redundancy is automatically enabled. In general, to use a 48v DC UPS (Uninterrupted
Power Supply) is highly recommended. A 48V DC UPS can be either an AC to DC UPS or solar-powered DC backup
UPS.
Once the DC power is connected, the DC power functions as backup power. If the AC is not used and the DC power
is connected, then the DC power functions as the main power. When the DC power is used as the main power, the
actual power required will be based on the total power consumption fo the connected devices. For example, if
there are two high power devices with 60W each and two low power devices with 10W each. Then, the total
power consumption is 150W, including the system power consumption, i.e., the switch, and this means it requires
the DC battery to provide at least 3.13A DC power.
Please note, the DC Power Cord Kit, Part # WPCK-004, is an optional accessory.
