The Riello UPS's powering A & B Feeds to racks at DC06 in Poole are scheduled to be inspected and serviced on the 17th March by specialist UPS contractors.
The UPS's will be worked on in turn, with 1 UPS being fully online and protected while the other is worked on. It may be required to bypass the UPS being worked on and the affected feed to be running from the mains , with the associated loss of UPS resilience. If this is required and in the event of a power cut the other feed will still be backed by generator but will lose power during the transition.
As all racks are dual fed with 'A' and 'B' feeds no disruption is anticipated.
