11. Peculiarities and Restrictions for Releases
11.1 R27
1. The MCH can only be used in an OM6062 and ELMA K1 and K2 compatible chassis. I.e.
it can't control MTCA specification conformant intelligent and redundant power units and
cooling units.
2. No F-clock E-keying, according to AMC.0 R2. F-clocks for an AMC slot are automatically
supplied when the slot's payload power is switched on, by backplane hardware.
3. The payload power is switched by Mosfet switches on a proprietary I2C bus. I.e. no intel-
ligent power supply is supported.
4. No automatic presence detection for AMC modules. The population of the rack has once
to be defined explicit by an operator via CLI during startup. I.e. no intelligent power supply
is available
5. MCH firmware upgrade only 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.
6. The power consumption of the AMC modules will not be taken to account in the power
up phase of a module. Power will always be granted.
7. No clock E-keying is implemented. Please note that Kontron AMC modules until now do
not need clock e-keying (AM400x, AM401x, AM410x, AM5010). Please note that
OM6062 supplies every inserted module automatically with the F-clock.
8. The following FRU data records are not yet processed:
• "MicroTCA Carrier Activation and Power Management Record"
• "Module Current Requirement record" of the MCH and the AMC Modules
• "MicroTCA Power Policy Record"
• "MicroTCA Power Module Capability Record"
• "MicroTCA FAN Geography Record"
9. The following IPMI commands or command groups are not yet implemented:
• MicroTCA Commands
10. No XT1L temperature thresholds are used when an AM5901 hardware is detected.
11. Local MCH temperature is not used for temperature control. Only temperature events
from AMC modules will be processed.
12. Common Option's bit 20 (processPwrShutdownEvent) will be set as a default when the
MCH version R27 selects any configuration automatically. When bit 20 is set, some
events coming from AMC boards will be ignored (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
