The A1534 is the HV Supply board that is inserted into our SY1527(MTD:SY4527 ).
Currently used boards(03/01/2016) for TOF + MTD: serial number and firmware version
TOF(counting from 0):
slot 1(-): 54, 3.01
slot 3(+): 56, 2.02
slot 5(-): 55, 2.02
slot 7(+): 57, 2.02
MTD(counting from 0):
slot 1(-): 66, 04.
slot 3(+): 69, 3.01
slot 5(-): 71, 04.
slot 7(+): 61, 03.
slot 9(-): 59, 3.01
Spare(-): serial number 58
Bad boards:
#59(Neg) - channel 3 bad (ch. 0-5) [occurred ~2/5/16 in SY4527 while in slot 1, was replaced with #66 on 2/17/16, then reinstalled in slot 9]
#66(Neg) - channel 3 bad (ch. 0-5) [occurred ~6/16/15 in SY1527LC spare while in slot 5, then installed and bl30,1 no data but reading back values when in slot 1 in 02/17/16]
-Email thread MTD BL 15-17 HV on MTDops 6/22-6/26/15.
-Not sure if this board was repaired between run15+16 and then failed again.
Spare:
#58(Neg) - possible bad channel 3 (ch.0-5). I think this was swapped in for #66 ~6/16/15(spare SY1257LC) and out for #71 ~2/02/16 (SY4527). Would have been in slot 5
Unaware of the positive spares available.
BTW: reoccurring issues on MTD BL15-17 from at least 1/17/2015 [slot 5 channel 3] and 5/11/2014, 1/31/2014...

Re: HV boards in need for repair (Bertrand H.J. Biritz)

Hi Bertrand, since there are so many bad boards now - Geary and I agree that we
should probably send them all in together a.s.a.p...
thanks, cheers,
bill
