Main arc circuits (MB & QF/QD) and correctors chains have been qualified at cold
Quench protection systems and associated heaters have been validated
Tests of Powering Interlock Controller are almost complete
 Powering of the arc magnets is imminent …
But repairs in sector 7-8 (replacement of 1055, PIMs, bus-bar on SSS 500, etc…) start early August
 Need 4 weeks for warm-up, power tests have to stop prematurely

Installation of warm beam pipes in long straight sections:
Components procurement Ok, ~200m/wk installed and activated
Advancement below expected rate, perturbed by:
Area not available: LSS3L/R or UJ62-63 (for dump line)
Co-activities: Point 6 (with kicker), Point 8R (with warm magnet tests)
Uncertainty on equipment installation: collimators in LSS7L/R

Sector 3-4: Delays with DSLC  cool-down without DSLC
Get experience with HW commissioning of 2 sectors in parallel
Time window for fixes after 1st HW commissioning period
Need for an extra warm-up/cool-down cycle
Sector 7-8: Repairs scheduled Aug.-Sept.  power tests stop early July
Sector 8-1: Repair low- (8R & 1L) before cool-down
Need to warm-up sector 7-8 before completion of first power tests program
Cool-down and test low- as early as possible
HW commissioning directly up to 7 TeV
