10.11.1.4 Forced FCLKA / PCI Express Reference Clock Configuration
The configuration option to forcibly set the FCLKA (ignoring E-Keying) may be useful during system
setup and testing and is available for each AMC base configuration providing a PCI Express interface.
The current setting can be shown or changed using the
kBoardConfig uEFI Shell command, option
AMCFclka.
Note:
When a base configuration is selected via the
kBoardConfig uEFI Shell command, option
AMCBaseCfg, the configuration option for the FCLKA is set to its default value (auto = E-
Keying).
10.11.1.5 Fail-Safe Mode
If the fail-safe mode is active, all AMC configuration options in
kBoardConfig are ignored. The fail-safe
mode is activated by setting the DIP Switch SW2, switch 1, to ON. For further information on the fail-
safe AMC fabric configuration, refer to Chapter 3.1.1, DIP Switch SW2.
