Chapter 1: Introduction 1-2 Chipset Overview The H8DMU+ serverboard is based on the nVidia MCP55 Pro chipset. The nVidia MCP55 Pro functions as Media and Communications Processor (MCP). Controllers for the system memory are integrated directly into the AMD Opteron processors. MCP55 Pro Media and Communications Processor The MCP55 Pro is a single-chip, high-performance HyperTransport peripheral controller.
H8DMU+ User’s Manual 1-3 PC Health Monitoring This section describes the PC health monitoring features of the H8DMU+. The serverboard has an onboard System Hardware Monitor chip that supports PC health monitoring. Onboard Voltage Monitors The onboard voltage monitor will scan these voltages continuously: CPU cores, Hyper Transport (1.2V), memory banks (1.8V), 1.5V, MCP55 Core, 3.3V, 12V, 12V, 5V, VSB and battery voltage.
Chapter 1: Introduction 1-4 Power Configuration Settings This section describes the features of your serverboard that deal with power and power settings. Microsoft OnNow The OnNow design initiative is a comprehensive, system-wide approach to system and device power control. OnNow is a term for a PC that is always on but appears to be off and responds immediately to user or other requests.
H8DMU+ User’s Manual Wake-On-Ring Header (JWOR) Wake-up events can be triggered by a device such as the external modem ringing when the system is in the SoftOff state. Note that external modem ring-on can only be used with an ATX 2.01 (or above) compliant power supply. 1-5 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. The H8DMU+ accommodates 12V ATX power supplies.
Chapter 1: Introduction 1-6 Super I/O The disk drive adapter functions of the Super I/O chip include a floppy disk drive controller that is compatible with industry standard 82077/765, a data separator, write pre-compensation circuitry, decode logic, data rate selection, a clock generator, drive interface control logic and interrupt and DMA logic. The wide range of functions integrated onto the Super I/O greatly reduces the number of components required for interfacing with floppy disk drives.
H8DMU+ User’s Manual 1-7 UIO The H8DMU+ is a specially-designed serverboard that features Supermicro's UIO (Universal I/O) technology. UIO serverboards have a PCI-Express x4, x8 and x16 signals that can support PCI-E cards or any one of several types of UIO card types to add SAS ports, additional LAN ports, Infiniband®, etc. to the serverboard. This allows the user to tailor the serverboard to their own needs.
Chapter 2: Installation Chapter 2 Installation 2-1 Static-Sensitive Devices Electrostatic 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.
H8DMU+ User's Manual 2-2 Processor and Heatsink Installation Exercise extreme caution when handling and installing the proces- ! sor. Always connect the power cord last and always remove it before 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.
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. 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.
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. Secure the retention module to the backplate with two of the screws provided. See Figure 2-1. Repeat for the second CPU socket.
Chapter 2: Installation 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.
H8DMU+ User's Manual Support The H8DMU+ supports single or dual-channel, DDR2-800/667/533 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).

H8DMU+ User's Manual 2-10 Enabling SATA RAID Serial ATA (SATA) Serial ATA (SATA) is a physical storage interface that employs a single cable with a minimum of four wires to create a point-to-point connection between devices. This connection is a serial link. The serial cables used in SATA are thinner than the traditional cables used in Parallel ATA (PATA) and can extend up to one meter in length, compared to only 40 cm for PATA cables. Overall, SATA provides better functionality than PATA.
