6.2.9 Configuration Not Readable

The internal bus used to communicate with the plug in modules and power supplies to determine
their type and serial number is the I2C bus. If this alarm occurs the system should continue to
operate correctly, but the unit should be power cycled at a convenient time to resolve this
extremely rare condition. It the alarm is still active after a power cycle, return the unit for repair.
