Note that it is normal for a certain amount of residue to be left behind when removing the CPU assembly. If broken buttons are observed, remove them carefully with the IPA lint free wipe. Take care to contain the debris and completely remove them from the system board socket. 15. Vacuum the system board socket site, being careful not to introduce contaminates in the process. 16. Carefully clean the system board socket with the IPA lint free wipe. 17. Install the CPU assembly into the appropriate CPU socket on the system board. Installing the CPU Install CPUs according to the procedure listed below: Step 1. Carefully align the CPU notches with the socket notches and set the CPU in place. Step 2. Tighten the four captive T-15 mounting screws that hold the CPU in place. NOTE Tighten the four CPU mounting screws a little at a time, in a cross pattern (1, 3, 2, 4), until they are all tight. The following picture shows both CPUs installed in a server. 136 Chapter
