Can IE3400 be supplied by two different voltage DC power supplies

[loadcell ron]

Good day

I am thinking if the redundant power supplied can be achieved with supplying the switch with two different voltage ranges

Example:

DC-A to be connected 12 VDC supply

DC-B to be connected to 48 VDC supply

hello @loadcell ron

Cisco IE 3400 series switches are designed to support redundant power supply configurations, but the power supplies must be of the same type and voltage. You cannot mix different voltage ranges for the redundant power supplies. In other words, both power supplies should have the same voltage specification.

I cant find any document warning that supply voltages need to match I have two power supplies one is a 24V DC and the other a 55VDC, it is easy to be lead to believe it would support two different supply voltages. where might I find this information so I can share with my team.
