MX250 Dual Power Supply Operation

[GFrazier]

I have an MX250 with dual 250WAC redundant power supplies.  In the "Security & SD-WAN / Power" setting both slots (1 and 2) are showing as "powering".

Does both power supplies draw at once? If so, do they draw at half capacity equaling 250WAC

OR does one provide power as the primary until a failover event? If so, how do I determine which one is drawing as a primary?

I don't know the answer for sure.

I believe it is an active/standby scenario.  You would need to use a power meter (like a metered PDU or wall socket energy meter) to confirm for sure which one was active.

They are redundant and not combined.

@GFrazier The reason they both show as powering is so you know that both power supplies are reciving power and they are operating normally. If one were to lose power, fail or be removed it would report otherwise.

While the wording isn't great its basically a green is goo and red is bad.
