Symptoms:

Burning a strategy to a controller's flash memory after a Secure Strategy Distribution (SSD) key has been programmed, causes the controller to become unresponsive after a power cycle. Following the power cycle, the STAT LED blinks green twice every 6 seconds.

  1. Connect a cross-over cable from your computer to the controller.
  2. Run PAC Terminal for Secure Strategy Distribution.
  3. Highlight the name of your controller, right-mouse click, and select Clear Private Key from Controller. The following dialog appears.

  10. Cycle power to your controller.
  11. The controller will BootP. Set the controller's IP address.
  12. Re-program the controller with the SSD key.
  13. Now you can download your strategy to the controller and store it to flash memory.
