H8DCE User's Manual 2-3 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. Make sure that the metal standoffs click in or are screwed in tightly. 1. Check the compatibility of the serverboard ports and the I/O shield The H8DCE serverboard requires a chassis that can support extended ATX boards of 12" x 13.05" in size.
Make sure that the I/O ports on the serverboard align with their respective holes in the I/O shield at the rear of the chassis. 2. Mounting the serverboard onto the mainboard tray in the chassis Carefully mount the serverboard onto the mainboard tray by aligning the serverboard mounting holes with the raised metal standoffs in the tray. Insert screws into all the mounting holes in the serverboard that line up with the standoffs. Then use a screwdriver to secure the serverboard to the mainboard tray - tighten until just snug (if too tight you might strip the threads). Metal screws provide an electrical contact to the serverboard ground to provide a continuous ground for the system.
2-4 Installing Memory CAUTION Exercise extreme care when installing or removing memory modules to prevent any possible damage. 1. Insert each memory module vertically into its slot, paying attention to the notch along the bottom of the module to prevent inserting the module incorrectly (see Figure 2-2). See support information below. 2. Gently press down on the memory module until it snaps into place. Note: each processor has its own built-in memory controller, so the CPU2 DIMMs cannot be addressed if only a single CPU is installed. 128 MB, 256 MB, 512 MB, 1 GB, 2 GB* and 4 GB* memory modules are supported.
It is highly recommended that you remove the power cord from the system before installing or changing any memory modules. *With Opteron 246 C-stepping CPUs and above. 2-4
