Status of RPC Commissioning
W+2 Completed (except horiz. Sectors) W+1 Completed (except horiz. Sectors) W0 Sector 4 and 5 to completion
Sector Test are done before final cabling

Status of RPC Commissioning RE+3 pre-commissioned RE+2 pre-commissioned RE+1 pre-commissioned RE-1/2 pre-commissionedMissing Front-End functional and read-out test and
cooling test. Few gas leakages to be fix and understood
Commissioning needs a clear resource allocation and commitments

Tower Test
On going Tower Test on Near Side Half Wheel +1
Step 1) Cabling: connectivity, CCU chain
Step 2) LV up: grounding and functionalities
Step 3) HV up: stability
Step 4) Data Acquisition: performance, full chain
Use of the MTCC set-up in Green and Balcony Barracks

Conclusion
Clear set of performance benchmark Sector Test on Barrel going smoothly Tower Test ala MTCC in preparation now Time to devote more effort on SW
Few items to follow up closely
