Hello,
Does a Cisco IE2000 require both DC inputs to be connected to the same power supply? Although this isn't fully redundant, my research has revealed that DC-A and DC-B are inputs to two different internal power supplies. Hence, I believe DC-A and DC-B could still benefit from some level of redundancy if connected to the same external power supply... Thank you for your response.
The power supplies are separate, therefore.
You can power the switch from either a single source or from two sources. It is the higher voltage power source that draws power from both power sources when both are operational. During a power outage, the switch remains powered by the other power source.
Connect each power supply to an independent source of power in systems configured with redundant power. A faulty external wiring or a tripped circuit breaker may result in total power loss if you fail to do this.
