Redundant DC Terminal Block Power Inputs
There are two pairs of power inputs can be used to power up this device. You need to have
two power inputs connected to run the device, but the FAULT LED indicator will light up to
remind that the power redundant system functions abnormal in case either PWR1 or PWR2
is dead. This device, however, continues working normally even fault LED indicator lights
up.
Step 1: Connect the DC power cord to the plug-able terminal block on the switch, and
then plug it into a standard DC outlet.
Step 2: Disconnect the power cord if you want to shut down the switch.
