15. TDCB cabling is painful
In all the crates with a new tel62 board (A3, A4, A5, A6, A7) we have connected TDCBs and LAVFEE boards.
This is NOT an easy task, as there are plenty of noisy and dead channels.
The situation is not stable as, apparently, problems might be solved (in lucky cases) just by “massaging” the cables…
We managed to get rid of noisy channels in LAV3, 4, 5
According to me, this will be a constant problem during the run, and we will be forced to mask noisy channels, that will fill up the buffers and prevent the DAQ to work properly.

16. Status on 1st of August We have 28 installed boards.
L052 and L079 boards have some minor problems
L087 is a “half board” to be used in LAV6-8
Raspberry Pis now have a remote NFS drive on pcna62lnf1
TEL62s and TDCBs should be coming at CERN in next few days
A10 PS is at Electronics Pool to get some minor repairing.
Missing Raspberry PI are scheduled to arrive on week 34

17. Status on 1st September All crates and PS are in place
Cabling is done in 11/12 stations
All 81 LAVFEE boards have been tested, calibrated and are now in place (Thanks to Matt, Silvia, and Venelin)
LAVFEE firmware is updated in all but A7 and A12
We have only 2 working spares
We have 12 raspberry Pis (A9, A10, A11, and A12 are B+)
Some issues with A11 crate/power supply (under voltage on 48 V)
TDCB cable issue: noisy and dead channels

18. Plan for next weeks
As soon as new TEL62s arrive: installation cabling: and dead/noisy channel hunting
How many dead channels can we really afford?
Upgrade the fw in all LAVFEE and prepare DCS calibration files with Rasberry Pis
Cosmic data taking using as many stations as possible should be done and analysed before the run
Need to do Ethernet Cabling: 5 ~4m-cables per station
Setup and test self-trigger or use Torino L0TP
