Present: Cédric Verilhac, Diego Real, Francesco Filippini, Giuliano Pelegrini
-50 CLB V2.2.1 delivery: Should be sent to IFIC. Packaging not conform to KM3NET req. Diego said we never found damage about packaging and handling from manufacturer.
Stephane asked Tecnint a photo of the cardboard with CLB+PB inside. Individual packaging seems a little bit light :

Diego is in favor to give green light under Tecnint responsability
SC has checked the datapackage.
Action : Diego validation also requested == > see KM3NeT_ELEC_2023_021_MDP_CLBV2.2.1_TECNINT
-CLB testbench:
Diego think testbench for CLB is a low priority. Stephane explain FMC connector and Octopus connector are not tested. Since the Xray analysis on BGA FPGA and FMC connector is perfomed before press fit insertion, then no damage could be seen.
Tecnint has made a proposal:

Giuliano said for the FMC board the use a Genesys board to test the signal, only the change in the FPGA the LVDS signals into single ended signals
Diego said FMC is needed only on a fraction of board, then he suggest to ask to integration site to perform the functionnal test.
Francesco said Giuseppe will be happy to collaborate in order to create a link between the Dia tool and the testbench
Diego said we only should remind to Tecnint to insert an octopus board for mechanical test of the CLB connectors. But no need to test octopus connectors.
Action: Stéphane asked people to comment in order to send requirmeents to Tecnint for an offer

KM3NeT_ELEC_2023_024_005_TESTBENCHES_requirements
Rhe goal is to ask to tecnint an offer to improme in the future CLB testbench.
Francesco said its not a big deal to automatize the testprocedure (script can send command and store results in files)
Diego said main problem on actual test setup are related to transceivers (sometimes works, sometimes not...)
Calibration AHRS : stopped... Comment requested in the Git? (Diego, David) :
https://git.km3net.de/calibration/calibration-status/-/issues/1#note_61529
-FMC : 2 connectors Abracon to replace FMC RJ45 connectors received from ARTEL yesterday @ Bologna. A test is planned next week with hydrophone
Stephane send the reference of the new transformer selected by Colmar : oilcraft
mod.TTWB3010-1.
Stephane will ask to Colmar if they can give us one or 2 for tests?
-Track phase issue and connection/disconnection ==> NRB should be organized (Action : Cédric, Diego)
-Diego want to separate Elec and reliability meeting.
Monday 12h-13h : Elec meeting
Friday : 10h-10h30 : Reliability
Next meeting friday 8th 10h30
