Configuring FlexAddress
FlexAddress is an optional upgrade that allows server modules to replace the factory-assigned
WWN/MAC ID with a WWN/MAC ID provided by the chassis.
NOTE: By using the racresetcfg subcommand, you can reset the Flex Address of a CMC to its
factory-default setting, which is “disabled”. The RACADM syntax is:
racadm racresetcfg -c flex
For more information about the FlexAddress-related RACADM commands and data about the other
factory-default properties, see the
Dell Chassis Management Controller for PowerEdge FX2/FX2s
RACADM Command Line Reference Guide available at dell.com/support/manuals.
The server must be turned off before you begin configuration. You can enable or disable FlexAddress on
a per-fabric–basis. Additionally, you can enable or disable the feature on a per-slot–basis. After you
enable the feature on a per-fabric–basis, you can select slots to be enabled. For example, if Fabric-A is
enabled, any slots that are enabled have FlexAddress enabled only on Fabric-A. All other fabrics use the
factory-assigned WWN/MAC on the server.
NOTE: When the FlexAddress feature is deployed for the first time on a given server module, it
requires a power- down and power-up sequence for FlexAddress to take effect. FlexAddress on
Ethernet devices is programmed by the server module BIOS. For the server module BIOS to
program the address, it needs to be operational which requires the server module to be powered
up. When the power-down and power- up sequences complete, the chassis-assigned MAC IDs are
available for Wake-On-LAN (WOL) function.
Configuring FlexAddress for Chassis-Level Fabric and Slots
At the chassis level, you can enable or disable the FlexAddress feature for fabrics and slots. FlexAddress is
enabled on a per-fabric–basis and then slots are selected for participation in the feature. Both fabrics and
slots must be enabled to successfully configure FlexAddress.

The WWN/MAC Summary page allows you to view the WWN configuration and MAC address of a slot in
the chassis.
