2.3.6.11 CPLD State Sensor

The following table describes the discrete CPLD state sensor available on the physical SAM.
2.4 SAM1000 Active (Virtual) Shelf Manager
This section describes in detail all available IPMI sensors of the Active SAM1000 at IPMB
address 0x20. The information in this section supports the SAM on both the AXP1406 and
AXP1600 shelves. The AXP1600 FRU and sensor data is highlighted and/or marked for ease
of use.

2.4.1 FRU Information

FRU 0 of address 0x20 corresponds to the main FRU information of the respective Physical
SAM that is running as the Active SAM; it could be either FRU 0 of IPMB address 0xFC or FRU
0 of IPMB address 0xFE.
Active Shelf Manager FRU Data, AXP1406
There are an additional eight managed FRUs (FRUs 1 to 8) that correspond to each of the eight
fan trays that cool the chassis. The Active SAM FRU information is addressed as FRU 254
which is cached information from data stored as a FRU 1 in each of the PEMs (IPMB addresses
0x66 and 0x68).
