Manually proof test redundant CHARMs Smart Logic Solvers (CSLS)

The procedure for a redundant CSLS allows the proof test to be done online without adversely affecting the running process.

  1. The logic solver can be manually reset only when the CSLS is Unlocked. Select the CSLS in Diagnostics Explorer. If the value of the Locked parameter is Yes in the contents pane, right-click on the CSLS and select Unlock. Click Confirm on the Secure Write Confirmation dialog.
  2. Right-click the CSLS and select Force Reset on Standby. Click Confirm on the confirmation dialog.
  3. Wait for the Standby card to complete power-up tests and become configured by the Active card. The Partner Not Available maintenance alert goes inactive when the Standby card is fully configured.
  4. Right-click the CSLS and select Switchover. Click Confirm on the confirmation dialog.
  5. The previously reset Standby card becomes the new Active card and the new Standby card goes through power-up tests and is configured by the new Active card. The proof test timer is 0. There will be event records for the user reset and switchover commands and for the CSLS cards, confirming that power-up tests completed successfully.
