  • Page 17: General Description

    Cheetah 9LP Installation Guide, Rev. B General description Cheetah 9LP SCSI disc drives are high-speed, random-access digital-data storage devices capable of operating in single-ended (SE) or low voltage differential (LVD) modes. These two modes are offered to allow you to use this drive in systems that use the traditional SE technology or to use it in LVD-capable systems.

    Cheetah 9LP Installation Guide, Rev. B Initial setup information The general information beginning on this page applies to all of the Cheetah 9LP drive models. After reading the general infor- mation topics, refer to the appropriate drive-specific section listed below for additional information about configuring and installing your particular model.
  • Page 22 Single-ended and low voltage differential modes This drive incorporates two different transceivers to allow you to use it in traditional systems which may use single-ended (SE) drivers and receivers, or to use it in low voltage differential (LVD) capable systems which use LVD drivers and receivers. You can configure the drive to switch between SE and LVD modes automatically or force it to operate in SE mode only.
  • Page 23 Cheetah 9LP Installation Guide, Rev. B SCSI IDs are normally used for other SCSI devices such as this Cheetah disc drive. Note. Most SCSI controllers (host adapters) allow you to skip a SCSI ID. For example, you can have ID0, ID1, and ID3 (skipping ID2).
  • Page 24 Drive termination If you are installing a Cheetah drive in a system that has other SCSI devices installed, terminate only the end devices on the SCSI chain. A SCSI “device” is any disc drive, scanner, tape backup unit, or other piece of hardware connected to your sys- tem using the SCSI bus.

This is often referred to as providing “high-9 termination.” Figures 3, 4, and 5 show typical drive connections.

  • Page 30 Cheetah 9LP Installation Guide, Rev. B Providing adequate cooling The enclosure design must ensure adequate cooling for the drive. The maximum ambient temperature allowed is 50 C. The drive’s product manual (83329240) describes how to evalu- ate the air-flow design. The evaluation consists of ensuring that the case temperature of certain critical components remains within acceptable limits during drive operation.

  • Page 43 Cheetah 9LP Installation Guide, Rev. B Terminating the drive ST39102LW and ST34502LW drives do not have internal termi- nators or any other way of adding internal termination to the drive. You must provide external termination to these drives when termination is required. This is normally done by adding an in-line terminator on the cable.
  • Page 44 LW drives Terminator power You can configure this drive to supply termination power to the SCSI bus by placing a jumper on J2 pins 1 and 2. The default setting is no jumper, meaning that some other source (other than this drive) is suppling termination power to the SCSI bus.

Reserved Single-Ended Mode option Use single-ended or low voltage differential mode. Force the drive to operate only in single-ended mode.

  • Page 49 Cheetah 9LP Installation Guide, Rev. B Terminating the drive LC model drives do not have internal terminators or any other way of adding internal termination to the drive. You must provide external termination to these drives when termination is required. Since this drive is designed to be plugged into a back- panel or other host enclosure without cabling, this is normally done by enabling termination on the backpanel or plane.
