Chapter 1: Introduction 1-2 Chipset Overview The H8SSL-i2 serverboard is based on Serverworks' HT-1000 chipset, which functions as a HyperTransportTM SystemI/OTM Hub. The HT-1000 chipset provides high performance, scalability and reliability. Its HyperTransport architecture reduces IO bottlenecks to improve overall system performance. System memory controllers not part of the chipset but instead are integrated into the processors to decrease latency.
H8SSL-i2 User’s Manual 1-3 PC Health Monitoring This section describes the PC health monitoring features of the H8SSL-i2. The serverboard has an onboard System Hardware Monitor chip that supports PC health monitoring. Onboard Voltage Monitors for the CPU core, +3.3V, +5Vin, +12Vin, +5V Standby and Battery Voltage 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.
H8SSL-i2 User’s Manual 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 of 1 GHz and faster. The H8SSL-i2 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 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.

Chapter 2: Installation Chapter 2 Installation 2-1 Static-Sensitive Devices Electrostatic Discharge (ESD) can damage electronic components. To prevent damage to your motherboard, 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.
H8SSL-i2 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. Installing the CPU Backplates One CPU backplate (BKT-0017L) is included in the retail box. The backplate prevents the CPU area of the motherboard 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. Installing the Heatsink Retention Modules One heatsink retention module (BKT-0018L) and two screws are included in the retail box. Once installed, these are used to help attach the heatsink to the CPU.
H8SSL-i2 User's Manual 2-3 Mounting the Motherboard into a Chassis All motherboards have standard mounting holes to fit different types of chassis. Make sure that the locations of all the mounting holes for both the motherboard and the chassis match. Although a chassis may have both plastic and metal mounting fasteners, metal ones are highly recommended because they ground the motherboard to the chassis. Make sure that the metal standoffs click in or are screwed in tightly. 1.
Chapter 2: Installation Support The H8SSL-i2 supports unbuffered ECC/non-ECC DDR2-800/667/533 SDRAM. Both interleaved and non-interleaved (single and dual-channel) memory are supported. See procedure on following page for installation order. Populating two adjacent slots at a time with memory modules of the same size and type will result in interleaved (128-bit) memory, which is faster than non-interleaved (64-bit) memory. Maximum memory: 8 GB of unbuffered ECC/non-ECC DDR2-800/667/533 SDRAM. Figure 2-2.
