Difference: DCC2BoardDatabase (69 vs. 70)

Revision 7010 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: 98 to 98
 
2175 CERN Tested. Broken LED-->VME. Declared good, shipped to CERN 8/18/11 OK
2176 FED_727 31 July 2011: Removed from FED 703 due to BcN mismatch problems. This occurred during ramping and is likely not an actual DCC issue: http://cmsonline.cern.ch/cms-elog/631675
3 Aug 2011: Installed as FED 727 http://cmsonline.cern.ch/cms-elog/637389

2178 FED_705 Tested. Installed to replace 2160 - 10/29/09
10 May 2012: Installed as FED 705 to replace DCC with bad memoery.
5/10/12 OK
 
2179 FNAL Tested. Ship to FNAL 2011-05-12 OK
2180 BU Tested. TTS link error. SLINK error.   Sick
2181 FED_700 CRC erros and "miscellaneous errors" during intervention on a different DCC problem: http://cmsonline.cern.ch/cms-elog/637389
Was eventually tested for bad memory and failed memory test. This appears to have developed memory issue during the aforementioned intervention
26 Jan 2012: This board had the affected LRB chip replaced at the CERN e-shop. Today it tested AOK at 904. Back to pile of spares
