SEVERE: The UPS is on battery due to an error. Symmetra UPSes: Intelligence module has reported being in self-test for too long. When this happens, the UPS is not usually in self-test, but the batteries are draining slowly. If left uncorrected, the batteries will become depleted and the UPS will not be able to turn on. If UPS has at least N+1 redundancy, check power modules one by one to determine which keeps the UPS in self-test. Once identified, replace the module.
