RPC DCS for MTCC P. Paolucci - I. N. F. N. di Napoli MTCC meeting May 06 9

To be done for MTCC ü Move to RPC condition db on SX 5 and test the performance. ü Release the CMS_RPCfw. Hardware Component ü Help our Warsaw friends, creating a control and monitoring system of the LB low voltage, and integrate it into the RPC DCS. ü Do we want to integrate it in the FSM ? ? It will be also discussed tomorrow in the DCS working group. ü Test all the system when the hardware will be ready at SX 5 (June 06). ü Write documentation and organize training in order to have more people ready to take data.
