
EEPROMU - Verifies that the EEPROM contents are readable via I2C. Since the IPMC stores
its runtime and persistent data here, proper operation is crucial.

Master-Only I2CU - Verifies that all expected devices attached to the master-only I2C bus
are accessible.
To obtain results of POST, the IPMC supports the IPMI standard command,

with OEM extensions. This IPMI command can be run at anytime.
9.5 Ejector Handle De-Bounce
The handle switch de-bouncing algorithm is used to configure a programmable delay. The
IPMC waits before ejector handle state changes are accepted. This is provided to avoid
accidental FRU extraction caused by service-teams during servicing other FRUs.
The ejector handle de-bounce function can be enabled, disabled and configured with the use
of the OEM command,

9.6 FRU Inventory
The ATCA-7480 implements two intelligent FRUs (IPMC and MMC).
Every FRU provides its own FRU information (serial, part, MAC addresses). Depending on the
presence of a module, its FRU information is visible or not.
The FRU of the RTM is not hot-swappable. This is especially important to ensure that the system
management application (HPI-B) does not has to deal with dynamic FRU population.
