About FlexAddress Plus
Each FlexAddress Plus feature card contains unique pool of MAC/WWNs that 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
specic to a server slot.
Before installing FlexAddress, you can determine the range of MAC addresses contained on a FlexAddress feature card by inserting the SD
card into an USB Memory Card Reader and viewing the pwwn_mac.xml le. This clear text XML le on the SD card contains an XML tag
mac_start that is the rst 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. To determine the total MAC range allocated, use the following formula:
<mac_start> + <mac_count> - 1 = <mac_end>
For example:
(starting_mac)00:18:8B:FF:DC:FA + (mac_count)0xCF – 1 = (ending_mac)00:18:8B:FF:DD:C8
NOTE: Lock the SD card prior to inserting in the USB Memory Card Reader to prevent accidently modifying any of the contents.
You
must unlock
the SD card before inserting into CMC.
