Difference: DCC2BoardDatabase (71 vs. 72)

Revision 7210 Sep 2012 - PhilLawson

Line: 1 to 1
 
META TOPICPARENT name="DCC2Documentation"
10 Prototype boards with red front panels were manufactured in early 2009. These boards are not identical to the production boards because they have a smaller FPGA. The production front panels are marked "DCC2" and are black.
Line: 51 to 51

2131 P5 Spares 8 May 2012: Removed from FED 720 for spurious reasons (red herring): eLog entry
8 May 2012: Installed back in as FED 721 since the power cycle of previous intervention fried DRAM on 721 eLog Entry

2132 904 Hospital 23 Jan 2012: Removed because we were not receiving any events over VME in local run. Possible software issue: http://cmsonline.cern.ch/cms-elog/750159 23 Jan 2012 Sick
2133 904 Hospital Removed due to CRC errors during intervention on other DCC issues. Suspect spurious issue: http://cmsonline.cern.ch/cms-elog/637389
31 Jan 2012: Fails LRB memory test on LRB2, LRB3. Repaired, test ok 2012-03-06
31 Jan 2012 OK
2134 BU Returned to BU because of alleged mis-matches 5/26 Sick
Line: 68 to 68
 
2145 FED_703 "Stops sending events down SLINK and goes to OFW at 80 kHz" . Tested OK by PDL 4/1/11 11/16 OK
2146 BU Tested. Pin9 of HTR14 RJ45 to U14 line open. Could be a PCB problem.   Sick
2147 BU Tested. Two broken LEDs, Ethernet error(RJ 45), and CRC error. R25 cold solder,D25 is also missing. Errors fixed as of 6/3   OK

2148 904 Hospital 8 May 2012: Failed DRAM post power cycle at P5: eLog Entry
pseudo-random data not changing; test probably failed
Errors:  LRB3
5/10/2012 BAD LRB
 
2149 BU Tested. U0 soldering problem(most likely because U10 looks OK) Multiple lines to U10 without connection   Sick
2150 904 Hospital Developed memory problems on LRB2 (spigots 6,7,8) during the Dec 2011 shutdown: http://cmsonline.cern.ch/cms-elog/750642. Repaired, test ok 2012-03-06 24 Jan 2012 OK
