MPCMM0002 CMM—Grounding Considerations

10.0Grounding Considerations

10.1ESD Discharge Protection

The MPCMM0002 CMM has ESD discharge strips on its lower edge. Refer to Section 5.4, “ESD Discharge Strip” on page 27 for more information.

10.2Chassis Ground and Logic Ground

Section 4.2.3 of the PICMG 3.0 specification recommends that each FRU have a jumper to tie logic ground and chassis ground together. On the MPCMM0002 CMM, this jumper is accessible on Component Side 1 of the CMM near the ejector handle. Jumper J3 is normally jumpered between pins 1 and 2, which means no connection; move the jumper to connect pins 2 and 3 on J3 to connect these two grounds together. Refer to Figure 3, “CMM Top View Layout” on page 16 for the location of J3.
