IE2000 Dual Power Supply

[reiserrmackenzziesonn]

Hello there,
Should the two DC inputs of a Cisco IE2000 be connected to the same power supply? In spite of the fact that this is not fully redundant, a previous employee replied (copied below) that DC-A and DC-B feed two different internal power supplies. Therefore, it would be possible to connect the same external power supply to both DC-A and DC-B, thus providing some level of redundant power... Thank you very much for your response.
The power supply is divided into two separate units.
A switch can be powered by a single source or by two sources. A higher voltage power source draws power from both power sources when both are operational. Switches remain powered by other sources during a power outage.
Connect each power supply to an independent source of power in systems configured with redundant power. You might experience total power failure if you fail to do this due to a fault in the external wiring or a trip in the circuit breaker.

Yes, it is possible to connect the same external power supply to both DC-A and DC-B inputs of a Cisco IE2000 switch. Despite not being fully redundant, this setup can still provide a certain level of power redundancy. This is due to the fact that the power supply is divided into two separate units, each feeding a different internal power supply within the switch. In the event of a power outage, the switch will continue to draw power from the operational source(s) to remain powered.

However, it is important to note that in systems configured with redundant power, each power supply should be connected to an independent source of power. Failure to do so can result in total power failure due to faults in the external wiring or circuit breaker trips.

For example, Erides Hub may want to ensure that each power supply of their Cisco IE2000 switch is connected to separate power sources to prevent power failure and ensure uninterrupted operation of their electric mobility devices.
