Caution: Always handle the module by its edges. Do not touch the components, pins, leads, or solder connections.
Caution: If you meet strong resistance when attempting to seat the module using the ejectors, remove it from the chassis and confirm that the slot is one designed to hold the module. Also, be sure that you have aligned the top and bottom edges in the correct matching tracks.
Caution: Be sure to cover every empty slot with a blank faceplate to protect the system from dust or other foreign substances and to ensure proper system cooling.
Caution: Do not discard the antistatic bag. When a module is not in use, store it in an antistatic bag.
Order of Installation
