Works undertaken included extension of the basebuild LV power from level 38 down to level 12 from both A&B streams to their respective rooms, with a bus coupler link between the switchpanels controlled by the new PLC system. 4 UPS systems each supported a switchpanel for PDUs and Desk Workstations. Each floor contained 2 IDF rooms, and an MDF was located on level 12. Within these rooms PDU panels supplied the cabinets and cooling was supported by a mix of up flow and down flow CRAC units. All CRAC units are located within the hex room that sits adjacent to their IDF rooms.
