[j-nsp] M20 Strange powersupply numbering

[Jonas Frey]

Hi,

i do have a couple of M20 AC powersupplys here and all are labeled with
stickers on the connector side:
MOD PS2262    REV. A3
PN 740-007311 REV. 05

however these do get recognized completly different from JunOS:

Power Supply B   REV 03   740-001465   XXXXXX     AC Power Supply

Refering to the earlier M20 PSU fan problem, i wonder if these
powersupplys are affected or not. From the bulletin i see:
unaff: M20 AC PWR-M20-AC-S 740-007311 Revision 1 and later 
affect: M20 AC PWR-M20-AC-S 740-001465 Revision 7 and earlier 

So the stickers say they are unaffect but JunOS says they are.
Whats true? Anyone from Juniper able to clarify?

Regards,
Jonas Frey
