C9407 show power incorrect

[fhk-cwempe]

I wanted to check how much power our new Catalyst 9407 is consuming.

The switch is configured and running.

There is only one Access Point connected. No other clients.

Power Summary          Maximum
 (in Watts)    Used    Available
-------------  ------  ---------
System Power   1535    1535
Inline Power   25      1665
-------------  ------  ---------
Total          1560    3200

But I think the "used System Power" should not be 1535 Watt for an idle switch.

Actually, I measured the power consumption is about 400 Watt.

Am I interpreting this wrong?

Can anybody reproduce this?

Is this a bug? (Cisco IOS XE Software, Version 17.03.03)

Thanks

If you are inspected Physically all good, try to reseat the PSU and see if that fix the issue 

then it is a bug in the new code, Raise TAC case.

The issue existed in 16.09.04, too.

I rebooted and updated today.

I will check if completely disconnecting from power (or how do I reset the PSU?) will help.

i corrected  the mistake i mean reseat PSU.

I think those are the correct numbers. here is an output from a 9410 with one port connected to it

Power Summary Maximum
(in Watts) Used Available
------------- ------ ---------
System Power 1870 1870
Inline Power 0 4530
------------- ------ ---------
Total 1870 6400

My older Catalysts (e.g. Catalyst 4507R+E) show a lower "used System Power" than the "Maximum Used Available".
