Chapter 2: Installation 4. With the CPU inserted into the socket, inspect the four corners of the CPU to make sure that it is properly installed and fl ush with the socket. 5. Gently press the CPU socket lever down until it locks in the plastic tab. For a dual-processor system, repeat these steps to install another CPU into the CPU#2 socket. Installing the Heatsink Retention Modules Two heatsink retention modules (BKT-0005) and four screws are included in the retail box. Once installed, these are used to help attach the heatsinks to the CPUs.
To install, position the module so that the CPU backplate standoffs insert through the holes on the heatsink retention module and the four feet on the module contact the serverboard. Secure the retention module to the backplate with two of the screws provided. See Figure 2-1. Repeat for the second CPU socket. Note: BKT-0005 is included for use with non-proprietary heatsinks only. When installing proprietary heatsinks, only BKT-0004 (CPU backplate) is needed. The BKT-0005 retention module was designed to provide compatibility with clip-and-cam type heatsinks from third parties. Figure 2-1.
CPU Backplate/Heatsink Retention Module Installation Installing the Heatsink We recommend the use of active type heatsinks (except for 1U systems). Use the Fan7 header for the CPU1 fan and the Fan8 header for the CPU2 fan due to fan monitoring and wiring considerations. To install the heatsinks, please follow the installation instructions included with your heatsink package (not included). 2-3
