Always connect the power cord last and always remove it be- fore adding, removing or changing any hardware components. CPU Backplates Two CPU backplates (BKT-0011L) have been preinstalled to the serverboard to prevent the CPU area of the serverboard from bending and to provide a base for attaching the heatsink retention modules.
  • Page 37 Chapter 5: Advanced Serverboard Setup 3. Align pin 1 of the CPU with pin 1 of the socket. Once aligned, carefully place the CPU into the socket. Do not drop the CPU on the socket, move the CPU horizontally or vertically or rub the CPU against the socket or against any pins of the socket, which may damage the CPU and/or the socket.
  • Page 38 See Figure 2-1. Repeat for the second CPU socket. Note: BKT-0012L is included for use with non-Supermicro heatsinks only. When installing Supermicro heatsinks, only BKT-0011L (the pre-installed CPU backplate) is needed. The BKT-0012L retention module was designed to provide compatibility with clip-and-cam type heatsinks from third parties.
