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.

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

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
