Dangerous voltages, capable of causing death, are present in this equipment. Use extreme cautionwhen handling, testing, and adjusting.Inserting or removing modules with power applied may result in damage to module components. Avoid touching areasof integrated circuitry as static discharge can damage these circuits.1. Attach an ESD strap to your wrist.2. Attach the other end of the ESD strap to an electrical ground.The ESD strap must be secured to your wrist and to ground throughout this procedure.Note: The system chassis may not be grounded if it is unplugged.3. Perform an operating system shutdown.4. Turn off the AC or DC power and remove the AC cord or DC power lines from the system.5. Remove chassis or system cover(s) as necessary for access to the VME base board.6. If the VME base board has already been installed in a VMEbus card slot, carefully remove it and place it withconnectors P1 and P2 facing you.7. Attach the four standoffs to the VME base board.For each standoff:a) Insert the threaded end into the standoff hole at each corner of the VME base board.b) Thread the locking nuts into the standoff tips and tighten.8. Place the XMCspan on top of the VME base board.9. Align the mounting holes in each corner to the standoffs and align XMCspan connector P3 with VME con-nector J6.10. Gently press the XMCspan and VME base board together, and then verify that the connectors are fullyseated.11. Insert four short screws (Phillips type) through the holes at the corners of the XMCspan and into thestandoffs on the VME base board12. Tighten the screws securely.6806800H03A | XMCspan Installation and Use | 25Hardware Preparation and Installation
