Photo shows that all racks other than the fibre opitcs patch rack have been removed from the MSR and the UPS rack is disconnected from the power circuits at the moment. Underfloor power upgrades are complete. We are still pulling out the old underfloor CDS cabling, carefully while maintaining active systems. A new cable tray has been installed under the floor which cuts across the centre of the main loop. Underfloor drawing is available on DCC
