    If there are any studs missing, you will know right away since the motherboard will not be able to be securely installed. Thunder H1000S (S3950) Mounting Hole Placement http://www.tyan.com...
  • Page 20 Some chassis include plastic studs instead of metal. Although the plastic studs are usable, Tyan recommends using metal studs with screws that will fasten the motherboard more securely in place. Below is a chart detailing what the most common motherboard studs look like and how they should be installed.
  • Page 21: Installing The Memory

    The following diagram shows the common types of RAM modules you may encounter depending on your board: Here are a few key points to note before installing memory into your Tomcat h1000S: • AMD Opteron processors support 64bit (non-interleaved) or 128bit (interleaved) memory configurations •...
  • Page 22 YOU MUST ALWAYS unplug the power connector to the NOTE motherboard before performing system hardware changes, to avoid damaging the board or expansion device. http://www.tyan.com...
  • Page 23: Installing The Processor And Heatsink

    2.21 – Installing the Processor and Heatsink Your Tomcat H1000S (S3950) supports the latest 64-bit processor technologies from AMD. However, only AMD Opteron processor are certified and supported with this motherboard. Reference the Tyan website for further details: www.tyan.com The following diagrams will detail how to install your processor: The processors you choose to use may not look exactly like the one pictured above, nor will the socket look exactly the same.
  • Page 24 Align the back plate screw bolts to the holes around processor socket on the back of motherboard. Align the heatsink retention frame to the back plate screw bolts on the front of motherboard. Insert screws to fasten the retention frame and back plate. Retention Frame Motherboard Back plate http://www.tyan.com...
  • Page 25: Thermal Interface Material

    CPU lid (applying too much will actually reduce the cooling). Always check with the manufacturer of the heatsink & processor to NOTE ensure the Thermal Interface material is compatible with the processor & meets the manufacturer’s warranty requirements http://www.tyan.com...
  • Page 26: Heatsink Installation Procedures

    Repeat this action on the other side of heatsink. 3. After securing metal clip to plastic retention bracket center tab, push down on plastic clip to lock plastic clip to side tab. http://www.tyan.com...
  • Page 27 (which should already be attached to the heatsink) to the motherboard. The following diagram illustrates how to connect fans onto the motherboard. After you’ve finished installing all the fans you can connect your drives (hard drives, CD-ROM drives, etc.) to your motherboard. http://www.tyan.com...
  • Page 28: Attaching Drive Cables

    IDE Drives Attaching IDE drive cabling is simple. The cable is “keyed” to only allow it to be connected in the correct manner. Tyan Tomcat h1000S has one on-board IDE connector, supporting two drives. The way to attach IDE cables to the IDE connector is illustrated below: Simply plug in the BLUE END of the IDE cable into the motherboard IDE connector, and the other end(s) into the drive(s).
  • Page 29 SATA Drivers The Tomcat H1000S is equipped with 4 Serial ATA (SATA) channels. Connections for these drives are also very simple. There is no need to set Master/Slave jumpers on SATA drives. Tyan has supplied two SATA cables and one SATA power adapter for boards equipped with the SATA option.
  • Page 30: Installing Add-In Cards

    Simply find the appropriate slot for your add-in card and insert the card firmly. Do not force any add-in cards (or anything else) into any slots if they won’t seat in place. It’s better to try http://www.tyan.com...
  • Page 31: Installing Optional So-Dimm Modules

    2.26 - Installing Optional SO-DIMM Modules Your Tomcat H1000S (S3950) motherboard is equipped with an optional proprietary SO-DIMM connector. The SO-DIMM connector can be used for expansion cards to provide such features as, additional SAS/SATA or SCSI support. For details of available expansions cards, visit the TYAN website at http://www.tyan.com.
  • Page 32: Connecting External Devices

    Zip drive, some external CD-RW drives and or other external devices. More on the uncommon side these days are the Serial Ports. They were primarily used to connect external modems, but most modems today are using USB or are installed internally. http://www.tyan.com...
  • Page 33: Installing The Power Supply

    NOTE: The Tomcat H1000S (S3950) peripheral drive power connector must be independent of any other devices. A device such as a DVD/CD-ROM drive, hard drive, or any other devices cannot be attached onto the same power line. If connected, system stability is compromised.

    Using a cache lowers data access times since the information is stored in SRAM instead of slower DRAM. Note that the cache is also much smaller than your regular memory: a typical cache size is 512KB, while you may have as much as 4GB of regular memory. http://www.TYAN.com...
