3.  We swapped 3 SMD boards for single channels: 
 
 
East Phi=11: 
Swapped SMD board on East Phi=11 to fix single channel 
problem on SMX0, ch10.   AFter swapping board, one bad 
channel went to 10 bad channels (ch 10 being one of these). 
Swapped a second SMD board and ch10 still problematic. 
 
Conclude original and final SMD board ok.    
 
send Board 564467-1F6  back to argonne for checkout. 
 
New SMD board 565229-31F 
 
East Phi=15 
Swapped board to try to fix problem with SMX ch0 (turned 
out to be SMXR problem so Old SMD board OK) 
Old SMD baord 564265-12C 
New SMD board 565279-31F 
 
 
4.  Swapped 1 SMXR board on East Phi=15 to fix a problem 
with pedcal32 readout on SMX ch0. 
 
Old Board 564523-62 
New Board 564508-47 
 
 
5.  Swapped termination board in West Phi=21 to fix fan 
readout.   Fanreadout sees only 1 fan on, although we 
know both fans are working.  This is either a problem 
in the taciometer circuit or else on the termination board. 
 
Swapping termination board has no effect on fan readout. 
 
Old board 564721 A.D=34 
New boad  564775 A/D=34

<pre>Late REPORT 
Wed Jun 19 03:18:06 
-------------------- 
 
SMX Access report.  
 
Determined Calibration failure in Ccal05, slot 4 (West Phi=16)  
to be a bad SMXR channel.  Swapped this board.  
 
We also swapped a SMD board in ccal11, slot 5 (East Phi=11) due  
to error bits in header word and channels failing in calibrations.  
 
Investigated cable disconnect identified   
from YMON plots on East Phi=14 (Wire channels in SMX2, ch 17-32).   
We found all cables connected.  
 
We ran stand alone  code to check swapped boards and these  
looked ok.  Couldn't confirm with DBANA due to  
problems getting calibrations into database.

<pre>SMX Access:  
----------  
 
West Phi=12 
We swapped a SMD board on CCal004, slot 3 SMX chan 4 due  
to header bit errors in data and channels failing calibrations.  
Old Board 564444-1DF 
New Board 564268-12F 
 
West Phi=12 
We found loose cable on West Phi=12, smx0 channels 16-25. 
Reconnected, another hole that will go away. 
 
East Phi=14 
This wedge has a hole 16 channels wide in the Wires. 
From pedcal, it looks like a cable is disconnected, 
i.e. preamps are alive, but ped. sigma's are 2.5 ish. 
 
We replaced the wire preamp board and protection board to wire 
channels on East phi=14, smx2, chan 17-32.  There was a bent 
pin on one of the strip preamp cards, so we replaced it too. 
From Pedcal, still looks like these channels do not see the 
detector, so this hole is most likely not fixed.  What next???  
Old Board              New Board   
133 S-2 (slot 3)        536 S-2 
203 W0  (slot 4)        462 W0 
 
 
Wphi=19:  
We were seeing preamp failures on all  4 strip boards (i.e., 
ped sigma around .5-1. cts) and these channels were failing 
pedcal sigma cut.  This was a sympton of dying preamps. 
Removed 2 strip preamps and the boards looked ok.  Mike  
noticed that all the SMD boards seemed loose and so he  
reinserted and screwed all SMD boards down. 
After Calibrations, all strip channels now look OK, 
even on the 2 boards we didn't change.  
Old Board           New Board 
518 S-3 (slot 2)     267 S-3 
526 S-3 (slot 3)     270 S-3 
 
 
East Phi=19. 
Steve reported that photon data showed this wedge showed lower 
occupancies.   We checked All cables on 19E for miscabling. 
Cables OK.</pre>

<pre>SMX work south arches, Larry N. & Jimmy P. 
Swapped SMD cards in 6W (4 & 5). 
Checked 10W CPR cabling, was ok, no change. 
Checked 9W CES cable swap, discovered it was swapped and  
switched it, and discovered that 8W did not have protection 
diodes and we put them in. 
Checked cable on 9E, heard a click poking around, there is 
some hope it is fixed.</pre>

<pre>Late POSTING for access work done Fri Jun 28 12:56:42  
 
Report on SMX work done by Karen & Mike (who are now off  
camping). Fixed a loose pre-amp board in W 3 Swapped cables  
(& labels) in W 19 and E 19.  Measured a few things on W4, but  
it all looked good Ran calibrations afterwards. One problem which  
we think is associated with the timing tests. Once the crate was  
returned to its normal condition, calibrations were OK. -  
documented by Jimmy Proudfoot 
 
-- Fri Jun 28 13:17:06 comment by...Jimmy Proudfoot --  A  
correction - Max re-ran the SMQIE calibrations with the cem  
splitter installed & it had no effect. So what we saw earlier is 
a bit puzzling. </pre>

SMX work:  
  Mike found and reconnected 2 loose cables on East Phi=9.  
This should fix 2 holes in the YMon strip occupancy plots.  
He also looked for a loose cable or loose SMD board or   
preamp board on West Phi=2, but found nothing obvious.

<pre>  Mike swapped a preamp board and set of protection diodes 
to West Phi=2, strip channels 32-48. (SMX1).    Calibrations 
looked OK for this wedge so hole in YMON occupancy for West 
Phi=2 should be fixed.  
 
We did note standalone pedestal readings showed 
pedestal splitting on capids for west phi=1 through 9. 
Didn't continue looking at all the phis, but west phi=0 
looked ok.   Pedestal calibrations using DBANA looked ok 
and splitting wasn't obvious.</pre>

<pre>ShowerMax Access Work - After the Fact: 
---------------------------------------- 
 
 
- Fri Jul 12 13:48:00  
 
Shower Max Access report (Larry N. & Mike L.):  
 
At last some offline production electrons appeared revealing  
some CES swapped cables, 10W wire 1 &lt;-&gt; wire 49 (and company,  
bundles of 2 strip and 1 wire cable) and 4W wire 16 &lt;-&gt;wire 49.  
OK, andmittedly we should have picked up 10W from the ymon plots.  
Anyway, both check out in hardware and are fixed. Both wedges  
were about 25% efficient due to the swap, so data up to now (since the shutdown) should be marked 
bad for shower max.

- Mon Jul 22 15:14:58  
 
SMX access report:  
 
Swapped 2 SMD boards with single channel problems.  
One on West Phi  = 6 (SMX5)  
One on West Phi = 5 (SMX6)  
 
Also checked Fan connectors which are used by PSM program  
and rseated BNB module to East PHi=9 and 11. These wedges had  
shown fans as being off intermittently in the past week.     
Don't think i fixed any connections,  
since fans were reading 100% prior to my intervention and they  
still read 100%.  I unmasked these crates in the PSM program.  
 
Unfortunately, West PHi=6 and 7 and the 2 top SW VME crates   
are now not readable by the PSM (purple states).  Roberta  
was notified and this fix will have to wait till the next   
access.  I masked these channels off.

Old SMD board 564265-12C for West Phi=6, new board 565224-2E3</pre>


<!-- Date: Mon Aug 12 20:11:41 2002 -->
<pre>SMX Access Report  
 
1.  Replaced an SMXR in ccal01, slot 5 (West PHi=5, SMX Ch 6 was reporting error bits).    
 
2.  Installed a ferrite on HV input to East Phi=18.     
 
3.  Recycled power on ccal13, slots 3 and 4 to fix SMXRs which were failing calibrations   
(presumedly due to power recycling by Min-jeong earlier  
today.  
 
4.  Lastly, fixed a PSM communication problem with East phi=4.

<pre>SMX access report.    Recovered 3 SMXRs which failed to respond  
after Roser power cycled for Min-jeong earlier this morning. 
SMXRs in Wphi=7,Ephi=8 and Ephi=22. 
 
Also reseated and recabled the SMXR in ccal11, slot 5 (Ephi=11)  
which has been reporting HRR errors at a low error rate. 
 
Swapped CPR SMD boards in West Phi=5 (reporting header error bits 
in data) and in West Phi=18 which showed many channels (9-14)  
failing charge injection calibration for 1 CapID on Range 0. 
 
This latter problem was not fixed.

<pre>SMXR in Ccal01, slot4 giving HRR errors. 
 
This is a peculiar problem which we still do understand. 
On Sep 23, 2002, we replaced the SMXR in ccal01, slot5 
(west phi = 5) 
because it was giving errors (recovered by HRR),  with a 
rate of a few a run.  As it turned out, we installed this 
SMXR back into ccal01, slot4 (west phi=4) where it lived  
and took data for approximately 1 month with no errors!  
 
 On Oct. 24, 2002, there was an access and this VME ccrate was 
 power cycled for min-jeong's had asd tdc boards.  In addition, 
 a cpr SMD board was swapped at west phi=5.  After this, 
the SMXR in ccal01, slot 4 (west phi=4) again started spewing 
errors (recovered by HRR) at a rate of a few a run.   In the  
last week, some of the longer runs (~ 1pb-1) have seen as  
many as 8-14 of these errors.</pre>

<!-- Date: Tue Nov 19 10:08:08 2002 -->
<pre>Swapped the 3 SMXRs on Ccal06 with modified SMXRs.  The modifications are to allow the FPGAs on the SMXRs to be reconfigured via software.     
 
We had some problems with calibraitons with one of the modified 
SMXRs.   It would not calibrate.  We reseated the board several 
times and recabled the board.  We power cycled many times. 
Eventually, we just replaced the SMXR.
