Please be advised of the following maintenance window:
Maintenance Window: Monday May 29th, 2023 - 9:00am - 11:00am Eastern Time
Affected Device: UPS-A.tor2
Affected Customers: Tor2 Dedicated/Colocated customers
Service Impacting: No - Precautionary Notice Only
Details: During the previous battery inspection and replacement performed on 19-May-2023, two sub-optimal batteries were identified in UPS-A.tor2's battery string, but only one replacement battery was on-hand to be immediately installed.
A second identical battery has been procured, and we will be swapping the remaining defective battery during this upcoming maintenance window. With both batteries replaced, this should return the string to optimal condition.
As with most maintenance windows, we expect the UPS to be on battery bypass for only a short duration during the window in question. Updates will be posted to our twitter feed as per usual @ https://www.twitter.com/pcolomaint/ .
While we do not expect this to be a service impacting maintenance, UPS-A.tor2 will be operating on battery bypass during the battery swap, 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.
