It is suggested to use only up-to-date IPMI versions and to set bit 20. In that case special
Hot Swap events ("Backend Power Failure" and "Backend Power Shut Down") will be
processed at any time as well. From MCH version R28 on bit 20 will be set as a default.
Please note: In R27 the description of the function of bit 20 was incorrect.
11.2 R28
1. The MCH can only be used in an OM6062 and ELMA K1 and K2 and OM6060 compatible
chassis. I.e. it can't control MTCA specification conformant intelligent and redundant
power units and cooling units.
2. Now the FCLKA is handled in the systems mentioned above.
3. Intelligent standard power supplies and fan controllers at IPMB-0 still are not handled.
4. MCH firmware upgrade is only possible by serial interface using a "Flash Tool" (lpcFlash,
Flash Magic). No firmware backup and roll back to the former firmware version after a
failed upgrade is implemented.
5. No AMC.0 R2.0 compatible clock e-keying is implemented. In OM6060 where the FCLKA
must be switched on individually for every slot this will be done whenever a PCI Express
connection is installed during e-keying.
6. The following FRU data records are not yet processed:
• "MicroTCA Power Module Capability Record".
• "MicroTCA FAN Geography Record".
7. The following IPMI commands or command groups are not yet implemented:
8. MicroTCA Commands
9. Local MCH temperature is not used for temperature control. Only temperature events
from AMC modules will be processed.
10. Common Option's bit 20 (processPwrShutdownEvent) will be set as a default when the
MCH version R28 selects any configuration automatically. When bit 20 is not set, some
events coming from AMC boards will not be processed (filtered) in distinct M states to
avoid e.g. unwanted shut downs. This event filtering is needed to run Kontron boards with
not up-to-date IPMI firmware versions:
• AM4001: IPMI version < 18hex.
• AM4002: IPMI version < 18hex.
• AM4010: IPMI version < 14hex
• AM4011: IPMI version < 12hex
• AM4100: IPMI version < 12hex
• AM4101: IPMI version < 11hex
• AM5010: IPMI version < 15hex
