  • Page 22: Processors

    Figure 2-2 Processors The SGI 1200 server motherboard can be populated with up to two Intel Pentium III processors. The processors on the motherboard must be rated at the same clock speed. Contact your sales or customer support representative for information on upgrading your server’s processors.

  • Page 23: Figure 2-3 Scsi Cabling Route To Midplane With Optional Raid Controller

    Theory of Operations • The floppy controller on the motherboard connects to the floppy drive. • The IDE controller on the motherboard connects to the CD-ROM drive. • The Ultra-2 SCSI controller on the optional PCI-based RAID controller connects to the midplane providing hot-swap RAID capability for four or five hard drives.

  • Page 24: Midplane

    Figure 2-4 Midplane The SCA midplane on the SGI 1200 server provides easy hard drive removal and replacement. Adding a RAID controller supports hot-swap capability for SCA-2 hard drives using Ultra2 SCSI technology on a single channel. All bus termination and SCSI ID selection for SCA hard drives is handled automatically by the midplane.

    Chassis Tour Chassis LEDs, Buttons and Connectors There are two push buttons and several LEDs on the right hand side of the SGI 1200 server front panel. The following sections provide information about the buttons and LEDs on the front and back panel, and information about error conditions that the LEDs can indicate.

  • Page 28: Reset Push Button

    The SGI 1200 server continues to have AC power inside the chassis even after the front power push button has been pressed to power down the SGI 1200 server. As long as the AC power cord is connected, the power supply supplies DC power so that the motherboard can be controlled through the Emergency Management Port (EMP) for remote management, fan usage and processor cooling.

  • Page 33: Mounting The Server In A Rack

    Service personnel could be seriously injured and equipment damaged if the rack topples over. Make sure that only one SGI 1200 server at a time in the rack is extended forward on slides. Install all equipment into the rack from the lowest available position.

  • Page 34: Slide Rail Mount

    4. Press the tab, and remove the slide from the rail. 5. Place the SGI 1200 server on a flat surface and attach the right and left side slide rails. Line up the five screw holes on each side, and install five 1/4-inch (0.64 cm) length 10-24 screws to attach each slide.
  • Page 35 At the back of the rack, line up the rear screw holes and attach the 10-24 rack screws on the right and left sides. 7. With one person holding each side, slide the SGI 1200 server chassis with slides attached onto the rails into the rack. Line up the slides and rails carefully on each side, press the locking tabs, and slide the chassis into the rack.

  • Page 41: Peripheral Use

    Chapter 4 Peripheral Use There is no front cover on the four hard disk drive locations. To access or use the CD and floppy drives, you must open or remove the plastic front cover. The following section describes how. Opening the CD and Floppy Cover As shown in Figure 4-1, the plastic front cover swings open to the right.

  • Page 42: Hot-Swap Drive Use

    Never remove more than one hard drive carrier from the SGI 1200 server at a time. All RAID levels fail when more than one hard drive is removed from the chassis. Also, do not operate your SGI 1200 for extended periods without having all drive bays filled with either devices or a filler drive blank.

Note: If you are using an optional RAID controller, you must have the RAID configured properly to remove and replace a hard drive carrier with the power on.

  • Page 45: Figure 4-4 Removing A Hard Drive

    Hot-swap Drive Use 3. Slide the hard drive out, see Figure 4-4. Caution: If you do not have an optional PCI RAID card you will probably lose data on a failed drive. You will need to restore backup data after the failed drive is replaced. Also, allowing 30 seconds for the hard drive to spin down after releasing the drive handle is highly recommended.
