The S1682D has two built-in VRM's on board. 2. 9 Peripheral Device Installation Install the motherboard after you have checked all of the jumper settings. Also be sure to check all connectors thoroughly and read the technical manuals that come with your peripheral cards before you install your addon peripheral cards. If a PCI-Bus interface card is to be installed in the system, any one of the five PCI-Bus slots will support either a Master or a Slave device. 2. 10 Connecting the Power Supply and On/Off Switch The system is configured for a standard ATX power supply. The ATX connectors can only be plugged in one way and should install easily. S1682D-001-02 http://www. tyan. com 18 Chapter 3: CPU Installation and Removal Pentium II (233 through 300MHz) and Pentium Pro Processors (150 through 200 MHz) can be used on the S1682D. Please refer to section 2. 3 for the correct CPU jumper settings for your board. Although the S1682D motherboard is designed as a dual CPU system, it will also function with a single CPU. The S1682D board provides two slots for Pentium II Processors--(Pentium II Primary and Secondary Slots). If only one CPU is used, the CPU should be plugged into the Primary Slot. However, when two CPUs are used, these CPUs should be of the same speed and type. The CPU is a sensitive electronic component which can be easily damaged by static electricity. Do not touch the CPU pins with your fingers. 3. 1 Installation of Pentium II Boxed (Active) Processors (Note: Active Processors are equipped with cooling fans. When installing an Active CPU, you also need to connect the cooling fan cable to its connector. ) Installing CPU Retention Modules 1. Installation of a Pentium II Active Processor requires a CPU Retention Module, which is first secured onto the motherboard. To attach the Retention Module, place the motherboard on a flat surface. Then carefully line up the key notch on the Retention Module with the key pin on the Pentium II Slot. (The key pin on the Pentium II Slot indicates the correct orientation of the CPU. ) Pentium II Slot Connector and Key Pin S1682D-001-02 19 4. Drop the Retention Module down over the Pentium II Slot so that the Retention Module seats flat against the motherboard. Tighten the screws in a clockwise manner to secure the module to the board. (Warning -- Do not overtighten the screws as you may damage the module and/or the motherboard. ) Retention Module Installing CPUs 5. [. . . ] To achieve this purpose, the LM78, a hardware monitor component, has an on-chip temperature sensor, 5 positive analog inputs, two inverting inputs and an 8-bit ADC. A 32-byte auto-increment RAM is provided for POST (Power On Self Test) code storage. Features The LM78 includes the following features: * Temperature sensoring * 5 positive voltage inputs * 2 op amps for negative voltage monitoring * 3 fan speed monitoring inputs * Input for additional temperature sensors * Chassis Intrusion Detector Input The software program-- LDCM (LANDesk Client Manager) is used as the LM78's drivers to accomplish monitoring computers' temperatures and voltages. The LDCM Drivers use the LM78 to monitor critical hardware components and enable remote sensing and diagnostics of your S1682D Board. [. . . ]
