On the 5th of July 2010 there will be a maintenance window to expand the capacity of the UPS systems. An additional UPS control unit and its associated batteries will be added to the existing cluster. This is to ensure the UPS system continues to provide fully redundant power backup as the site grows. This work creates an “at risk” period for your service. This maintenance is not service-affecting, but during the maintenance period services are at an increased risk.
During the maintenance period the critical load will be transferred seamlessly from the UPS to the raw mains. When the maintenance is complete it will be transferred back seamlessly.
We have confirmed with Southern Electric that they have no maintenance scheduled during this period.
