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. |

Problem: DSP FW version 0x301c reports as version 0x0 on this board. Can program manually with DCC2Tool.exe w/o issues. CRC of DSP FW reported by DCC2Tool.exe is correct. |
6/1 (returned) |

Tested. 8/18/11 fail LRB4 test, however, this LRB is not in use (no spigots attached to HTRs)
Developed memory issues on LRB1 (sp 3,4,5) over Dec 2011 shutdown. Removed on 24 Jan 2012: http://cmsonline.cern.ch/cms-elog/750642 Now LRB1 and LRB4 bad |

Removed from FED 700 due to UERR on spigot 13 - 10/29/09.
27 Jan 2012: Cannot reproduce UErrs on lxcmdtest3 while running at 83 kHz. Board looks good |

3 Aug 2011: Removed because it is not sending events over VME. Perhaps DAQ software issue? http://cmsonline.cern.ch/cms-elog/637389
26 Jan 2012: Tested on cmsmoe4 in 904. VME readout works just fine. Returning to pile of good spares |

> | SN 2145 re-checked for SLINK integrity w/ fedkit. AOK. We should install this one @ P5 to be verified with MWGR before 2012 data taking
SN 2150 fails memory test on LRB2. This matches the symptoms of the spigots that were not working at P5.
SN 2160 Tests fine on lxcmdtest3 @ 43 kHz. Then we run again at 83 kHz (no TTS), HTRs are giving single bit errors which are corrected by DCC, but no UErrs show up on spigot 13 (this was the failure mode at P5). Returning to pile of good spares
