3.1 Introduction
The Intel NetStructure
®
MPRTM0020 Rear Transition Module is a non-intelligent RTM. A non-
intelligent FRU does not have a remote management controller (RMC) on board to communicate
with the SBC IPMC. Instead, all of the non-intelligent RTM sensors and FRU device information is
made available to the IPMC through direct device access. This is usually done via dummy I

C
sensor and storage devices. It is the responsibility of the IPMC to make the non-intelligent RTM
look like a separate intelligent FRU controller to the rest of the system.
3.2 RTM Installation Procedure
The MPRTM0020 RTM is mechanically compliant with the PICMG*3.0 specifications Revision 2
ECN1.
The RTM must be installed in an AdvancedTCA* chassis prior to installing the MPCBL0020
Single Board Computer.
Install the RTM as follows:
1. Remove the rear air management blade from an AdvancedTCA chassis (where applicable).
2. Locate the slot where the RTM is to be installed in the chassis. The RTM must be installed in
the same slot number as the MPCBL0020 Single Board Computer.
3. Open the top and bottom ejector latches and slide the RTM into the chassis by aligning to the
guide rails on the top and bottom of the chassis cage.
4. Ensure that the RTM is fully installed in the chassis by locking the top and bottom ejector
handles.
5. Tighten the faceplate retention screws on the top and bottom of the RTM faceplate. Ensure that
the screws are torqued to ~6 in-lbs using a torque screwdriver.
3.3 RTM Removal Procedure
Removal of the RTM from the chassis uses the following procedure:
1. Because the MPRTM0020 is not an intelligent RTM, removing the RTM causes the SBC to be
shut down. Ensure that the SBC is ready to be shut down before opening the bottom ejector
handle of the RTM.
2. Remove all interface cables from the RTM faceplate connectors.
3. Loosen the RTM faceplate retention screws with a screwdriver.
4. Open the top and bottom ejector handles on the RTM.
5. Remove the RTM from the chassis slot.
