  6. Summary of Recent Problems • A total of 14 problems were encountered in –Z testing and minus slice test • DMB -> 8 problems • TMB -> 2 problems • MPC -> 1 problems • CCB -> 1 problems • Crate -> 2 problems • These have come from a detailed testing series over 16 pcrates ME I&C -- PC Electronics

  7. Plan • Setting up dedicated board test area @ B904 lab • Multiple PCrates in place • Computer in place • Updating testing software on computer • Ready from 12-June-07 • Single test chamber in place • Procedure at B904 • Re-test each board in known environment • All those listed in all 3 tables above • Give experts a test facility to look at problem boards in detail • Averaging close to 1 problem per crate • Need to determine seriousness of each of these problems • Can we find ways to prevent or to fix these in place in the future ME I&C -- PC Electronics

  9. Message ID: 2097     Entry time: Sat May 19 12:50:42 2007 Author:ignatenko, ignatenk@physics.ucla.edu • Type:PC commissioning Subject:Problem with VME-1_2 crate Dear all, last Friday we met a problem that related to peripheral crate itself. We weren't able to "talk" to ALCT on ME-1/1/03 CSC, which were connected to the slots 2 and 3. But we were able to download the ALCT firmware to the chamber and read back all necessary information (like status ALCT) through the slot #4. We tried to talk to ALCT on ME-1/1/04 CSC (this CSC normaly connected to the slot #4) through slot #2 and we failed again. Moreover, whichever TMB or RAT board were inserted into slot #2 they showed the same type of problem. The bottom line - something wrong with PC backplane (most probable something wrong with the connector between the TMB and the RAT boards). We are going to swap VME-1/3 and VME-1/2 crates in the peripheral rack and go on testing trigger sector -1/2. Once we get approval for crate replacement we will replace the PC.

Wed May 2 11:20:12 2007, Greg Rakness, Gregory.Rakness@cern.ch, Electronics, swapped DMB ME-2/1/8 and ME-3/1/10 • Sun May 20 14:44:40 2007, Jianhui Gu, gujh@mps.ohio-state.edu, Electronics, swapped DMB ME-2/1/8 and ME-3/1/10 Message ID: 2098 • Entry time: Sun May 20 14:44:40 2007     In reply to: 1939 Author:Jianhui Gu, gujh@mps.ohio-state.edu • Type:Electronics Subject:swapped DMB ME-2/1/8 and ME-3/1/10 Check these two DMBs in Building 904: DMB#400: The Controller FPGA was not programmed. Reload the PROM, the FPGA is programmed. Tried different ways (single, or broadcast), all worked. So, this is a good board. DMB#074: The controller FPGA was not loaded. Reload the PROM, the FPGA still can NOT be programmed. Load older version of firmware, still can NOT be programmed. The PROM was re-soldered after initial assembly. It looks to me that there was problem with this PROM. So, this is a bad board. Suggestion: replace the PROM. (could be connection?) ME I&C -- PC Electronics
