Flashing The 6511RC has detected a power failure on a power bus. There may be a problem with the CPCI power supply system such as a failed power supply module in the chassis. The Model 6511RC will function normally with one power supply.

Inspect the power supplies in the CPCI chassis to identify and replace the failed power supply module. If the POWER LED continues flashing when all chassis power supplies are functional, contact Patton Technical Sup- port to determine if the Matrix Switch should be replaced.

Off No input power is being applied. Verify that at least one chassis power supply module is installed in the chassis and functioning normally.
