MPRTM0020 Technical Product Specification

– April 2006

Module Components

AP3[x] indicates that these T1/E1 signals are routed from PMC 3.

4.3.8

Alignment 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* 1-1469373-1 (or
equivalent). The Zone 3 alignment block (A2) is assigned a keying value of 7-3, and uses Tyco
7-1469373-3 (or equivalent).

4.3.9

ADM1026 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
I

C bus. These I

C signals are routed from the SBC IPMC through the P30 connector on the

Zone 3.

The SBC IPMC communicates with the ADM1026 using an I

C 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.
