    H8DM8-2/H8DME-2 User's Manual Processor and Heatsink Installation Exercise extreme caution when handling and installing the proces- sor. Always connect the power cord last and always remove it be- fore adding, removing or changing any hardware components. Installing the 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 23 Chapter 2: Installation 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 24 H8DM8-2/H8DME-2 User's Manual Installing the Heatsink Retention Modules Two heatsink retention modules (BKT-0012L) and four screws are included in the retail box. Once installed, these are used to help attach the heatsinks to the CPUs. To install, align the module with the standoffs of the preinstalled CPU backplate and with the four feet on the module contacting the serverboard.
