2. Upgrade status of the ECAL/HCAL HV control mezzanine board;  New control mezzanine board based on IGLOO2 FPGA was developed for usage with the HV and HCAL Cs calibration systems;  Two prototype boards were produced and assembled ;  Photo of the new mezzanine board in the left;  Firmware for the HV system FPGA has been redesigned and simulated;  The functional tests of these mezzanines were started in February and now near finish. LHCb calorimeter upgrade meeting 2/03/2016. A. Konoplyannikov Block-diagram of the High Voltage and LED intensity control signal and power supply distribution board (HV_LED_DAC). Reminder: HV_LED_DAC board Specification. Readout of the control voltages is implemented on the board by two ADCs. The DCU-ADC (on SPECS mezzanine board) readouts the HV control signals and VFC-ADC (on the mother board) readouts the LED intensity control signals. Outputs 200 outputs for the CW base control voltage distribution in range from 0 to 5 V with 12 bit precision. 8 outputs of the stabilized LV and +100 V power supplies for feeding the 8 groups of the CW bases. Voltages for CW base power: 1) +5.8 V, -5.8 V protected by fuses; 2) +100 V protected by relays. 8 connectors for distribution 16 LED intensity control signals in range from 0 V to +5 V with 12 bit precision and powering LED-PIN boards. Voltages for LED-PIN board: 1) +15 V for LED driver; 2) -30 V, +5.8 V, -5.8 V for PIN diode amplifier. Will be replaced with GBT-SCA mezzanine Will be replaced with IGLOO2 Control mezzanine

5. Upgrade status of the ECAL/HCAL HV control mezzanine board LHCb calorimeter upgrade meeting 2/03/2016. A. Konoplyannikov Powerful software has been developed for making the functional tests of the new mezzanine with a CALO HV- LED control board. Finally one HV-LED_DAC board equipped with a new control mezzanine has been tested in the LHCb pit. All tests were passed except one with block transfer to memory.

6. The LEDTSB boards will use the infrastructure of the FEB crate where they are installed.  In particular, they should use the Channel-B control lines of the crate to make synchronisation with LHC timing.  In the same time, as mentioned by LAL people, the slow control bus (as SPECS) and +5 V / -5V volt power is not foreseen in new FEB crate. CALO DCS – LEDTSB boards Proposal The LEDTSB boards have to be modified: 1.SPECS should be replaced by GBT-SCA mezzanine with e-link, a mini HDMI connector at the front panel could be used as e-link connector. 2.+5 and -5V power will be needed for calibration LEDTSB (this is the procedure which will be done at the beginning of operation). As we will not have ±5V lines in future crates, we can arrange powering during the calibration, e.g., using a laboratory power supply.
