Chapter 1: Introduction 1-4 Chipset Overview The H8DCE serverboard is based on the nVidia nForce Pro 2200/2050 chipset. The two main components of this chipset (the 2200 and the 2050) both function as Media and Communications Processors (MCPs). Controllers for the system memory are integrated directly into the AMD Opteron processors. 2200 Media and Communications Processor This MCP is a single-chip, high-performance HyperTransport peripheral controller.
H8DCE User’s Manual 1-5 PC Health Monitoring This section describes the PC health monitoring features of the H8DCE. The serverboard has an onboard System Hardware Monitor chip that supports PC health monitoring. Onboard Voltage Monitors for two CPU cores, Hyper Transport (1.2V), two memory banks (2.5V), nVidia 2200/2050 chipset (1.5V) The onboard voltage monitor will scan these voltages continuously. Once a voltage becomes unstable, it will give a warning or send an error message to the screen.
Chapter 1: Introduction Slow Blinking LED for Suspend-State Indicator When the CPU goes into a suspend state, the chassis power LED will start blinking to indicate that the CPU is in suspend mode. When the user presses any key, the CPU will wake-up and the LED will automatically stop blinking and remain on. BIOS Support for USB Keyboard If a USB keyboard is the only keyboard in the system, it will function like a normal keyboard during system boot-up.
H8DCE User’s Manual 1-7 Power Supply As with all computer products, a stable power source is necessary for proper and reliable operation. It is even more important for processors that have high CPU clock rates of 1 GHz and faster. The H8DCE accommodates 12V ATX power supplies. Although most power supplies generally meet the specifications required by the CPU, some are inadequate. A 2 amp current supply on a 5V Standby rail is strongly recommended.
Chapter 2: Installation Chapter 2 Installation 2-1 Static-Sensitive Devices Electric Static Discharge (ESD) can damage electronic components. To prevent damage to your system board, it is important to handle it very carefully. The following measures are generally sufficient to protect your equipment from ESD. Precautions • Use a grounded wrist strap designed to prevent static discharge. • Touch a grounded metal object before removing the board from the antistatic bag.
H8DCE User's Manual 2-2 Processor and Heatsink Installation Exercise extreme caution when handling and installing the processor. ! Always connect the power cord last and always remove it before adding, removing or changing any hardware components. Installing the CPU Backplates Two CPU backplates (BKT-0004) are included in the retail box. The backplates prevent the CPU area of the serverboard from bending and provide a base for attaching the heatsink retention modules.
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 flush 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.
H8DCE User's Manual 2-3 Mounting the Serverboard into a Chassis All serverboards and motherboards have standard mounting holes to fit 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.
Chapter 2: Installation Support The H8DCE supports single or dual-channel, registered ECC DDR400/333/266 SDRAM. Both interleaved and non-interleaved memory are supported, so you may populate any number of DIMM slots (see note on previous page and charts 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).
