Progress since last meeting:

• 12 VTP boards installed in Hall (Ben, Sergey): 10 in DC and 2 in FTOF sectors 5 and 6. Five more VTPs needs repair - in progress. Cabling under way, should be ready in few days (Vhris, Mark, Armen). All VTP installation may take couple of weeks because of needed repairs.

• HTCC from GEMC is included into trigger validation (Rafo, Sergey), we have now PCAL, ECAL and HTCC, FT (Andrea) and FTOF(Sergey) are in progress.
