Integration and Commissioning of the LHCb CALO Upgrade readout electronics for the LHC Run3 data taking period.

The LHCb experiment is due to be upgraded in 2018. The full detector will be able to take data from LHC collisions at 40MHz rate taking full advantage of the collider bunch crossing rate. The calorimeter electronics has been re-designed for the upgrade. One of the key ingredients of the new calorimeter upgrade is the ICECAL chip from the Barcelona group. The ASIC passed the Electronics Design Reviewof the LHCb collaboration and Production . Now the full electronics, where the ASIC is integrated into the PCB boards, connected to the remaining elements of the new LHCB CALO must be tested and comissioned, before it will start operation in early 2021. Together with the group of the LAL-Orsay, a mini-DAQ has to be tested and debugged to make sure the final installation will be capable to readout the CALO data at a 40 MHz rate
