Hi Guys,

Please be advised of the following maintenance window:

Maintenance Window: Tuesday March 15th, 10:00am - 1:00pm EST

Affected Device(s): UPS-A
Affected Customers: All circuits fed from UPS-A
Service Impacting: No - Precautionary maintenance notice

Details: UPS service contractors will be performing a in-depth testing and analysis of the battery banks that power UPS-A. While we do not expect this to be a service impacting maintenance, the UPS unit will be operating on battery bypass, and should utility power fail at this time, there will be an interruption in services as the Automatic Transfer Switch (ATS) switches power from utility to generator. As such, this should be considered a precautionary maintenance window. We expect the UPS unit to be on battery bypass for approximately 45 minutes during this maintenance window, allowing the technician sufficient time to perform the appropriate testing.

Regards,
