    Working in the Subchassis and Electronics Bay Working in the Subchassis and Electronics Bay The chassis is comprised of three parts: • the main chassis • a swing-out subchassis at the front • a swing-out subchassis, called the electronics bay, at the rear To access components in some instances, you must swing away and/or completely remove the subchassis and electronics bay.

  • Page 20: Figure 1-2 Opening The Subchassis And Electronics Bay

    Chapter 1: Working Inside the System 10. Using the vertical edge of the electronics bay as a handle, rotate the bay right, away from the main chassis, until it stops. 11. If necessary, completely remove the subchassis and electronics bay: this requires rotating the bays outward until the two pins that function as hinges for the bays slide out of their slots.

  • Page 28: Scsi Requirements

    Chapter 1: Working Inside the System SCSI Requirements One narrow and two wide SCSI cables are standard in the system. All SCSI devices must be unterminated except the peripheral at the end of the SCSI cable. Hard drives usually provide an active termination, while CD-ROM drives do not. Because we recommend putting hard drives only in the internal bays, this means that you should route the SCSI cable so that the last device on the cable is a hard drive in the internal bay.
  • Page 29 Peripheral Drives It is important that your cabling and connections meet the SCSI bus specification. Otherwise, the bus could be unreliable and data corruption could occur or devices might not work at all. The SCSI bus needs to be terminated at the end of the cable; this is usually provided by the last SCSI device on the cable.

  • Page 40: Installing An Individual System Fan

    Chapter 1: Working Inside the System Installing an Individual System Fan Note: A general rule about correct airflow direction: The removable fan pulls air from in front of the chassis so that it flows across the boards and out the back. Thus, the fan must be oriented for the correct airflow direction.

  • Page 41: The Power Share Board

    The server comes with three power supplies already installed for highest power availability. If one supply fails, the system can operate using two until a replacement is installed. Your SGI 1400 system has a power share board (PSB). The PSB supports one to three supplies.
