Automatically proof test redundant CHARMs Smart Logic Solvers (CSLS)

Automatic proof testing is available for redundant CSLSs only. The Proof Testing tab of the CSLS Properties dialog has an Enable automatic proof test to run at reminder time check box. When checked, the CSLS performs the proof test when the number of days since the last reset reaches the configured time. The automatic proof test will begin after the CSLS sets the reminder alert. At the time of automatic proof test:

• The Active card starts the test by initiating a switchover to the Standby card. If the Standby card is not available, the Active card tries again periodically.
• After switchover the Standby card becomes Active and the new Standby card goes through reset and begins power-up testing. There is no adverse impact to the running process. An event record confirms successful power-up testing.
• The new Active card may still have a proof test due, and if so, it waits for its partner to become available then initiates a switchover. When the partner has become the Active card, the new Standby card goes through reset and power-up testing. An event record confirms successful power-up testing of the CSLS card.
