Page 22: Processor And Heatsink Installation
H8DMU+ 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. 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 H8DMU+ 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.
Page 25: Mounting The Serverboard Into A Chassis
Chapter 2: Installation Mounting the Serverboard into a Chassis All serverboards and motherboards have standard mounting holes to ﬁ t different types of chassis. Make sure that the locations of all the mounting holes for both the serverboard and the chassis match. Although a chassis may have both plastic and metal mounting fasteners, metal ones are highly recommended because they ground the serverboard to the chassis.
Page 26 H8DMU+ User's Manual Support The H8DMU+ supports single or dual-channel, DDR2-667/533/400 registered ECC SDRAM. Both interleaved and non-interleaved memory are supported, so you may populate any number of DIMM slots (see note on previous page and chart on following page). The CPU2 DIMM slots can only be accessed when two CPUs are installed (however, the CPU2 DIMM slots are not required to be populated when two CPUs are installed).
