card contains an XML tag mac_start that is the first starting hex MAC address that is used for this unique
MAC address range. The mac_count tag is the total number of MAC addresses that the SD card allocates.
The total MAC range allocated can be determined by:
<mac_start> + <mac_count> - 1 = <mac_end>
For example:
(starting_mac)00188BFFDCFA + (mac_count)0xCF - 1 = (ending_mac)00188BFFDDC8
.
NOTE: Lock the SD card prior to inserting in the USB Memory Card Reader to prevent accidentally
modifying any contents. Unlock the SD card before inserting into CMC.
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.
