Users Guide

NOTE: The SD card must be physically installed in CMC, and the chassis must be powered-down before executing the
deactivation command.
If you execute the deactivation command with no card installed, or with a card from a different chassis installed, the feature is deactivated
and no change is 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 powered-down prior to execution, the command fails with the following error message:
ERROR: Unable to deactivate the feature because the chassis is powered ON
For further information on the command, see the feature command section of the Chassis Management Controller for Dell PowerEdge
M1000e 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: In this section, the term FlexAddress also indicates FlexAddress Plus.
Purchase and install the FlexAddress upgrade to configure the FlexAddress. If the upgrade is not purchased and installed, the following
text is displayed on the Web interface:
Optional feature not installed. See the Dell Chassis Management Controller Users Guide for
information on the chassis-based WWN and MAC address administration feature. To purchase this
feature, please contact Dell at www.dell.com.
If you purchase FlexAddress with your chassis, it is installed and active when you power up your system. If you purchase FlexAddress
separately, you must install the SD feature card using the instructions in the Chassis Management Controller (CMC) Secure Digital (SD)
Card Technical Specification document 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 then 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.
Selected slots have FlexAddress enabled for all fabrics that are enabled. For example, it is not possible to enable Fabric-A and B, and have
Slot 1 be FlexAddress enabled on Fabric-A but not on Fabric-B.
NOTE:
Make sure that the Blade Servers are powered off before changing the fabric level (A, B, C, or DRAC) flex
address.

Wake-On-LAN with FlexAddress
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.
