OneNet will perform critical maintenance on our Automatic Transfer Switch (ATS) this Friday, August 26th between 5:30 PM and 9:30 PM. This maintenance will not cause a total power outage. There will be a brief power outage on the “A” power feed while it is moved to our temporary generator. This cutover will last approximately 5 minutes. The same outage will occur on the “A” power feed when we move it back to UPS power after the ATS maintenance is complete. The “B” power feed will run on primary UPS battery power during the ATS maintenance which will last 15 to 20 minutes. The only time a single power source will be available is during the connect/disconnect of the temporary generator. The maintenance should be completed in 1 hour, but the entire window is reserved.
Additional failed parts were identified during the maintenance on the 26th. An additional similar maintenance is scheduled now for the 27th from 6:00 PM until 2:00 AM on the 28th.
