4.3.8Alignment Blocks
The MPRTM0020 Rear Transition Module implements the rK1 and A2 alignment blocks at the top of Zone 2 and Zone 3, as required in Section 2.4.4 of the PICMG 3.0 Specification. The Zone 2 alignment block (rK1) is assigned a keying value of 11, and uses Tyco*
4.3.9ADM1026 Controller
The RTM has an ADM1026 controller that collects sensor information from the board using the SMBus interface. It also has memory to store FRU and user information.
The ADM1026 is managed by the MPCBL0020 Single Board Computer IPMC connected via the I2C bus. These I2C signals are routed from the SBC IPMC through the P30 connector on the Zone 3.
The SBC IPMC communicates with the ADM1026 using an I2C address of 0x5C. From the Shelf management perspective, the RTM can be managed using the IPMB address fronted by the SBC (MPCBL0020) with a FRU Device ID of 0x04.
Refer Section 5 for further information regarding management of the FRU and SDR data of the RTM.Table 13 shows mapping between GPIO signal name and pin on the ADM1026.
