1 André Augustinus HLT power (CR2) Due to RCU upgrade HLT expects to double computing power 150kW -> 300kW Cannot be all UPS (will compete with DAQ) Proposal HLT: All Y-racks on UPS (17) All X,Z-racks on EXD (18) 5 Z rack as reserve Estimate per rack: ~9kW (mono) ~ 15A per phase -> 30A per depart close to limit (32A), needs perfect balance over phases To be discussed with EL 34th ALICE DCS Workshop18 March 2013

3 André Augustinus HLT power (CR2) New cables from new switchboard to new splitter box installed Splitter boxes not yet installed (but prepared) Old cabling (EXD, Hazemeyer) still in place 34th ALICE DCS Workshop18 March 2013

4 André Augustinus Turbines UX racks Many failures Fan gets loose from motor Will need to order 100 pairs Perform exchange close to racks (limit transport) Will do a test exchange with Fred to estimate time and place needed 34th ALICE DCS Workshop18 March 2013
