Mechanical Information—MPCMM0002 CMM
There is only one ejector on the CMM, but it matches the subrack interface geometry defined in Section 2.2.7 of the PICMG 3.0 specification. Note, however, that the ejector handle is 2 mm (0.0787 inches) thick, not the 2.5 mm (0.0984 inches) thickness that many PICMG 3.0 boards use.
A switch on Component Side 2 of the PCB detects the opening and closing of the ejector handle.
5.3Rear Connector Placement
5.3.1MPCMM0002 CMM Rear Connectors
The CMM uses three connectors (for power, data, and a guide pin) that can mate with either vertical (backplane) connectors or coplanar connectors. The power connector is an FCI*
5.3.2Coplanar Mating Connectors
In a coplanar mating arrangement, a FCI* HM1L54LDP000H6P connector with FCI*
5.3.3Vertical Mating Connectors
When a CMM board mates directly into a backplane, vertical mating connectors are used. The data connector that mates to the CMM is a FCI*
Example: If mounted horizontally with Component Side 1 up, the bottom row of holes for the data connector is 1.775 mm (0.0699 inches) lower than the power connector.
5.4ESD Discharge Strip
The ESD strip along the bottom of the CMM follows the guidelines in Section 2.2.5 of the PICMG* 3.0 specification. The electrical definition of the ESD discharge strip is shown below.
