Users Guide

You must 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 turn on 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
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.
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.
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.
Configuring FlexAddress for Chassis-Level Fabric and Slots Using CMC Web Interface
If a server is present in the slot, turn it off before enabling the FlexAddress feature on that slot.
To enable or disable fabric and slots to use the FlexAddress feature using the CMC Web interface:
1. In the left pane, click Server Overview → Setup → FlexAddress..
2. On the Deploy FlexAddress page, in the Select Fabrics for Chassis-Assigned WWN/MACs section,
select the fabric type (Fabric-A or iDRAC) to which you want to enable FlexAddress. To disable, clear
the option.
3. On the Select Slots for Chassis-Assigned WWN/MACs page, select the Enabled option for the slot to
which you want to enable FlexAddress. To disable, clear the option.
