8.7 FRU Inventory
The ATCA-9405 implements two intelligent FRU's (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 important to ensure that the system
management application (HPI-B) does not have to deal with dynamic FRU population.
Dynamic inventory data of the SFPs is read at OS level.
The MAC addresses of an FRU are stored within the multi-record area of the FRU information.
Artesyn has defined a MAC address multi-record for this purpose, for more information see
MAC Address FRU OEM records on page 133 .
