About FlexAddress

The FlexAddress feature is an optional upgrade that allows server modules to replace the factory-assigned World Wide
Name and Media Access Control (WWN/MAC) network IDs with WWN/MAC IDs provided by the chassis.
Every server module is assigned unique WWN and/or MAC IDs as part of the manufacturing process. Before
FlexAddress, if you had to replace one server module with another, the WWN/MAC IDs changes and Ethernet network
management tools and SAN resources had to be reconfigured to identify the new server module.
FlexAddress allows CMC to assign WWN/MAC IDs to a particular slot and override the factory IDs. Hence, if the server
module is replaced, the slotbased WWN/MAC IDs remain the same. This feature eliminates the need to reconfigure
Ethernet network management tools and SAN resources for a new server module.
override action only occurs when a server module is inserted in a FlexAddress enabled chassis; no
Additionally, the
permanent changes are made to the server module. If a server module is moved to a chassis that does not support
FlexAddress, the factory-assigned WWN/MAC IDs is used.
The FlexAddress feature card contains a range of MAC addresses. 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 file. This clear text XML file on the SD card contains an XML tag
is the first starting hex MAC address that is used for this unique MAC address range. The
number of MAC addresses that the SD card allocates. The total MAC range allocated can be determined by:
<mac_start> + 0xCF (208 - 1) = mac_end
where 208 is the mac_count and the formula is:
<mac_start> + <mac_start>
For example:
(starting_mac)00188BFFDCFA + 0xCF = (ending_mac)00188BFFDDC9
.
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.

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
