Installation Procedures For VME64xP (VIPA) Compliant Modules To Reduce Damage To VME64xP (VIPA) Subracks, Modules And Transition Modules
    In an effort to reduce the number of incidents and severity of damage to VIPA equipment, the Equipment Support Department of the Fermi Computing Division has compiled the following guidelines for the insertion of VME64xP compliant modules into VME64xP subracks.  Extraction instructions can be found here.

    VME64xP MODULE INSERTION GUIDELINES
    The insertion of modules and transition modules into VIPA64x subracks is accomplished in 4 main steps.  ALWAYS FOLLOW PRECAUTIONS FOR HANDLING ELECTROSTATIC SENSITIVE DEVICES.


    STEP 1)
    Acceptable Vertical AlignmentUnacceptable Vertical AlignmentInsert module into card guides, ensuring that the module is inserted in the guides for the slots intended.

     STEP 2)
    Initial Backplane ContactOnce aligned in the slot, make sure the upper capture/eject handle points toward the top of the subrack.  The lower handle should point toward the bottom of the subrack.  Slowly push the module into the subrack until the module first contacts the backplane connectors.  This can be felt as a sudden increase in effort required to push the module further into the subrack, and the capture/eject handles will automatically begin to point toward the user.  This can be visually approximated by looking at the lower capture/eject mechanism. An increase in effort required to push module into subrack prior to initial contact with the backplane indicates that the module is encountering some sort of misalignment or a blockage of the card guides.  Double check to make sure module is in the correct guide rails or remove module and visually inspect the card guides.

    NOTE: INSTALLATION OF TRANSITION MODULES
    Due to the relatively short depth (120 mm) of typical transition modules, it is common for the connectors to be skewed by as much as 2.5 mm in a up-down and/or left-right position with respect to the backplane connectors as the connectors begin to meet.  Therefore, it is a REQUIRED practice to visually verify the position of the transition module connectors prior to full mating.

    STEP 3)
    Press Fit To Backplane Using thumbs, begin pushing on the top and bottom of the module, just to the inside of the capture/eject handles, until the module can no longer be advanced.  Modules with fully loaded J0, J1, J2 and J3 connectors will require a greater force (up to 60 lbs.) to seat.

 
 
 
 
 
 
 
 
    Capture/Eject Handle AlignmentWhen the module is fully seated in this step, the Capture/Eject handle should be aligned similar to this image.

    STEP 4)
    Module Fully EngagedPull the handles toward the center of the module.  Module will "snap" into position as connectors make full contact as the module locks into place.  Modules with fully loaded J0, J1, J2 and J3 connectors will require a greater force (up to 60 lbs.) to seat.

    EXTRACTION
    Pull handles toward outer edge of module until module snaps out from contact with the backplane.  Pull module out of subrack.
