PowerChute plus records the event of switching to Source B as Self Test Failed: Invalid Test. Examine the Redundant Switch front panel or the front panels of the Smart-UPS units for details. MONITORING THE AVAILABILITY OF THE REDUNDANT SMART-UPS Redundant Switch continuously monitors the power delivery capability of the redundant Smart-UPS.
Redundant Switch - Applications Guide March 22, 1999 SWITCHING FROM PREFERRED SOURCE TO REDUNDANT SOURCE Redundant Switch switches load delivery to the redundant Smart-UPS when it detects that the power feed from Source A is unable to deliver power to the load. In this case, the availability of the system drops from very high (with both Smart-UPS available to provide AC power and battery back up) to the standard availability power protection afforded by a single Smart-UPS.

Visit the installation to further diagnose the situation / restore the System, SWITCHING FROM PREFERRED SOURCE TO REDUNDANT SOURCE Redundant Switch switches load delivery and communications to the redundant Smart-UPS when it detects that the power feed from Source A is unable to deliver power to the load.
Redundant Switch - Applications Guide March 22, 1999 MONITORING HIGH AVAILABILITY Redundant Switch of the Redundant Smart-UPS System checks the availability of both Smart-UPS units to deliver power to the load. You can view the availability of both UPS-A and UPS-B at the Redundant Switch front panel (refer to the Redundant Switch User’s Manual- part number). The Smart-UPS units are preset to self-test every two weeks.

Redundant Switch - Applications Guide March 22, 1999 Smart-UPS Settings Follow the information given in the Smart-UPS User’s Manual to select the correct Smart-UPS configuration for the power environment. Follow the Redundant Switch PowerChute plus Configuration Procedure in the Redundant Switch User’s Manual if you plan to protect a server running a supported operating system with this Redundant Smart-UPS system. This procedure guides you through configuring the Smart-UPS units using Redundant Switch.
Redundant Switch - Applications Guide March 22, 1999 MONITORING THE AVAILABILITY OF THE REDUNDANT SMART-UPS Redundant Switch continuously monitors the power delivery capability of the redundant Smart-UPS. When Redundant Switch senses that its power feed from Source B is unable to deliver power to the load (if it were to be engaged) PowerChute plus records the event as Self Test Failed: Invalid Test, or as Alternate UPS engaged or Lost Comm.
