NPM 10.4 Hardware Health

I have a question on what I am seeing and how to interpret the display I am seeing.  I have a 3 switch stack of Cisco 3750X's.  When I look at the Solarwinds Hardware Status, I get this:

But via the CLI, I see this:

OP12SW1#sho env pow all

SW  PID                 Serial#     Status           Sys Pwr  PoE Pwr  Watts

--  ------------------  ----------  ---------------  -------  -------  -----

1A  C3KX-PWR-1100WAC    LIT15381AQ1  OK              Good     Good     1100/0

1B  Not Present     

2A  C3KX-PWR-350WAC     LIT15380TNZ  OK              Good     Good     350/0

2B  Not Present     

3A  C3KX-PWR-350WAC     DTN1536L089  OK              Good     Good     350/0

3B  Not Present  

Now I understand the 'B' power is the RPS.  No biggy there.  But why does the Solarwinds show SW1 as "Not Functioning" when it clearly is?  Is it because this one has a different PS in the device (and therefore a bug in NPM)?

Thanks,

Jim
