About FlexAddress Plus
The FlexAddress Plus is a new feature added to the feature card version 2.0. It is an upgrade from FlexAddress feature card
version 1.0. FlexAddress Plus contains more MAC addresses than the FlexAddress feature. Both features allow the chassis
to assign World Wide Name/Media Access Control (WWN/MAC) addresses to Fibre Channel and Ethernet devices. Chassis
assigned WWN/MAC addresses are globally unique and specific to a server slot.

FlexAddress Plus has 2928 addresses divided into 16 server slots, thus each slot is allocated with 183 MACs.
