Plan
Setting up dedicated board test 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

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.

Entry time: Sun May 20 14:44:     In reply to: 1939 Author:Jianhui Gu,
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?)
