Catalyst 3750X Fan error

I have installed a new Stack of Catalyst Switch 3750X (2x WS-C3750X-24T-S).
Network Lan works good by I think to have a cosmetic error:

FAN 1 is OK
FAN 2 is OK
FAN PS-1 is OK
FAN PS-2 is NOT PRESENT

Both fans of couple of Switch work good with green led.

Can you confirm my impression?

Many Thanks!

Re: Catalyst 3750X Fan error

Fan 4 is the optional PS fan.  If you don't have an optional Power Supply installed then don't worry.

Re: Catalyst 3750X Fan error

Yep, don't worry. The web device manager should not show failure when the fan is not detected when the PS is not installed.

Re: Catalyst 3750X Fan error

I have the FAULTY fan error in device manager on a 3750x as well.  We should not see an errror if it is not actually an error!

If we are to accept that the fan always displays as faulty then how would we know when there really is a faulty fan?
