10.0 Grounding Considerations
10.1 ESD 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.
10.2 Chassis 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.
