Deactivating FlexAddress
The FlexAddress feature can be deactivated and the SD card returned to a pre-installation state by using a RACADM command.
There is no deactivation function within the Web interface. Deactivation returns the SD card to its original state where it can be
installed and activated in another chassis. The term FlexAddress, in this context, implies both FlexAddress and FlexAddressPlus.
NOTE: The SD card must be physically installed in CMC, and the chassis must be turned off before running the
deactivation command.
If you run the deactivation command without installing an SD card, or with a card from a different chassis installed, the feature is
deactivated and change is not made to the card.
To deactivate the FlexAddress feature and restore the SD card:
racadm feature -d -c flexaddress
The command returns the following status message if it is successfully deactivated:
feature FlexAddress is deactivated on the chassis successfully.
If the chassis is not turned off before running the command, the command throws the following error:
ERROR: Unable to deactivate the feature because the chassis is powered ON
NOTE: To activate the FlexAddress feature again, re-boot the CMC.
For further information about the command, see the feature command section of the Dell Chassis Management Controller for
PowerEdge FX2/FX2s RACADM Command Line Reference Guide.
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.
Viewing World Wide Name/Media Access Control (WWN/MAC) IDs
The WWN/MAC Summary page allows you to view the WWN configuration and MAC address of a slot in the chassis.
