Viewing FlexAddress Mezzanine Card Fabric
Connections
In blade servers, FlexAddress allows the use of persistent, chassis-assigned World Wide Names and MAC addresses (WWN/
MAC) for each managed server port connection.
You can view the following information for each installed embedded Ethernet and optional mezzanine card port:
Fabrics to which the cards are connected.
Type of fabric.
Server-assigned, chassis-assigned, or remotely assigned MAC addresses.
To view the Flex Address information in iDRAC, configure and enable the Flex Address feature in Chassis Management
Controller (CMC). For more information, see the Dell Chassis Management Controller User Guide available at dell.com/
support/manuals. Any existing Virtual Console or Virtual Media session terminates if the FlexAddress setting is enabled or
disabled.
NOTE:
To avoid errors that may lead to an inability to turn on the managed system, you must have the correct type of
mezzanine card installed for each port and fabric connection.
The FlexAddress feature replaces the serverassigned MAC addresses with chassisassigned MAC addresses and is
implemented for iDRAC along with blade LOMs, mezzanine cards and I/O modules. The iDRAC FlexAddress feature supports
preservation of slot specific MAC address for iDRACs in a chassis. The chassisassigned MAC address is stored in CMC non
volatile memory and is sent to iDRAC during an iDRAC boot or when CMC FlexAddress is enabled.
