Difference: DCC2BoardDatabase (75 vs. 76)

Revision 7624 Oct 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: 64 to 64
 
2141 FED_723 Tested. 5/26 OK
2142 904 Hospital Prior incident as different FED (3/24/10): Was removed when we had an issue where no HTRs were sending data. No other symptoms point to DCC failure.
Removed on 10 May 2012 due to LRB DRAM failure: eLog Entry
9/10/12 BAD LRB
2143 FED_718 Tested. Ethernet error(RJ 45). Was not fixed. Returned to BU 6/9/09. Tested/shipped back to CERN
23 Jan 2012: Installed as FED 718 http://cmsonline.cern.ch/cms-elog/750159
