AM4024(E)
10.10 L AN Functions
Four Gigabit Ethernet channels on the board support IPMI over LAN (IOL) and Serial over LAN (SOL).
While IOL serves to transport IPMI commands and their responses via Gigabit Ethernet, SOL serves to
transport any serial data via Gigabit Ethernet.
Please note that IOL and SOL need the Ethernet device to be powered. Therefore, the board (payload)
must be fully powered. For information on the assignment of the IOL/SOL channels, refer to Chapter
2.7.9, Gigabit Ethernet Interfaces.
10.11 E-Keying
E-Keying has been defined in the AMC.0 R2.0 Specification to prevent module damage and malfunc-
tions and to verify the bay connection compatibility. Therefore, the FRU data of an AMC module con-
tains PICMG-defined records which describe the module’s AMC interoperability:
» Module Current Requirements Record: indicates the maximum power consumption of the
AM4024(E)
» Clock Configuration Record: configures the PCI Express reference clock (FCLKA on AMC Card-
edge connector)
» AMC Point-to-point Record: indicates the AMC port capabilities of the AM4024(E), i.e. the
supported AMC fabric interface types of the current board configuration
Depending on the current board configuration (i.e. the module’s description in the FRU data records),
the carriers’s IPMC (in an ATCA system) or the MCH (of a MicroTCA system) decides during E-Keying
which AMC fabric interfaces are activated. Therefore, the IPMI commands
Set AMC Port State
and Get AMC Port State defined by the AMC.0 specification are used for either granting or re-
jecting the E-Keys (i.e. enabling or disabling of AMC ports during E-Keying).
10.11.1 AMC Module Configuration Options
The board configuration for E-Keying is done via the kBoardConfig uEFI Shell command. For further
information on the kBoardConfig uEFI Shell command, refer to Chapter 9, uEFI BIOS.
For information on the AMC interconnection capabilities and the fabric interfaces supported for an AMC
base configuration, refer to Chapter 2.8, AMC Interconnection.
The following table indicates the fabric interfaces available and which board configuration options can
be applied to the module and its AMC base configuration.
