On March 16th, starting at noon, one of vendors will begin working to replace all of the batteries in one of the three UPSes in Santa Rosa.  This particular UPS is configured in such a way that we will be able to replace the three active battery chains individually without affecting the runtime or sacrificing internal redundancy of the UPS.  As such, this planned and fully scripted maintenance is expected to have no impact on any services.  -Kelsey and Russ
