Release Notes devices with SG550XG devices in the same stack. In a hybrid stack, features and tables are supported only if both device models support them. Table sizes are set according to the lowest table size between device types in a stack. To downgrade a device from version 2.2.5.x to a previous versions (2.2.0.x or lower), the device must be set to native mode. • PoE power consumption history—Support is provided for tracking and displaying PoE port consumption values (in watts) over time.
