Cheetah 9LP Installation Guide, Rev. B 19 Initial setup information The general information beginning on this page applies to all of the Cheetah 9LP drive models. After reading the general information topics, refer to the appropriate drive-specific section listed below for additional information about configuring and installing your particular model.
20 Cheetah 9LP Installation Guide, Rev. B 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.
Cheetah 9LP Installation Guide, Rev. B 21 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). Other controllers do not allow this so be sure to refer to your system or controller user’s manual for details about its requirements for proper SCSI device installation. Note. This drive is SCAM (SCSI Configured Auto Magically) compliant.
22 Cheetah 9LP Installation Guide, Rev. B 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 system using the SCSI bus. Note. Use active (ANSI SCSI-2 Alternative 2) single-ended terminators when terminating a bus operating in singleended mode.
Cheetah 9LP Installation Guide, Rev. B 23 plished by terminating the bus at the backpanel. For ST39102LW and ST34502LW drives, use an in-line terminator on the cable. Internal SCSI cable Internal SCSI device Internal SCSI device Controller Terminate Internal SCSI cable Internal SCSI device Internal SCSI device Controller External SCSI cable External SCSI device External SCSI device Terminate Figure 2.
24 Cheetah 9LP Installation Guide, Rev. B use these wide drives on a standard (non-wide) 8-bit data bus if you provide proper termination to the upper 8-bit data lines. This is often referred to as providing “high-9 termination.” Figures 3, 4, and 5 show typical drive connections. The following table lists the maximum cable lengths and number of devices using single-ended and LVD I/O circuits allowed on a daisy-chain cable for 10, 20, and 40 Mtransfers/sec I/O data transfer rates. Table 1.

28 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 evaluate the air-flow design. The evaluation consists of ensuring that the case temperature of certain critical components remains within acceptable limits during drive operation.

Cheetah 9LP Installation Guide, Rev. B 31 Mounting the drive and connecting cables Do not touch the connector pins or any components on the control board without observing static-discharge precautions. Always handle the drive by the frame only. The drive may be mounted in any orientation (horizontally, vertically, and any combination thereof); however, you must ensure that the drive receives adequate air flow for cooling. 1. Mount the drive to the host system’s chassis using four 6-32 UNC screws.

To connect the DC power cable to the drive, simply insert the cable end into the drive’s DC power connector. 4. Schließen Sie das SCSI-Kabel an den SCSI-Steckverbinder des Laufwerkes an. Das Kabel darf nicht gedehnt oder gedrückt werden und es darf den Luftstrom zur Kühlung des Systems nicht behindern.
34 Cheetah 9LP Installation Guide, Rev. B Note. Signal ground on the power control board (PCB) and the head and disc assembly (HDA) are connected together in this drive and you cannot separate them. The equipment in which you have mounted the drive is connected directly to the HDA and PCB without electrically isolating shock mounts. Maximizing the conductive contact area between HDA ground and system ground may reduce radiated emissions.

38 Cheetah 9LP Installation Guide, Rev. B Formatting the drive The drive has been low level formatted at the factory. You do not need to perform another low level format on this drive unless you decide to perform certain diagnostics through the host adapter. If you do decide to perform a low level format, do not abort the format as this is likely to make the drive inoperable. Also, it is a good idea to protect against power failure or other power interruptions during the format.
Cheetah 9LP Installation Guide, Rev. B 39 capacity drives. Refer to your system or utility manual for detailed instructions. • DOS/Windows 3.1/Windows 95. Set the drive type in CMOS to “Zero,” “None,” or “No hard drive installed.” Use FDISK.EXE and FORMAT.EXE. • Macintosh. Use a third-party drive utility or Apple’s Drive Setup (version 1.3.1 or later) to initialize the drive. Note: versions of Apple Drive Setup prior to version 1.3.1 do not recognize nonApple drives.

Cheetah 9LP Installation Guide, Rev. B 41 LW drives Terminating the drive ST39102LW and ST34502LW 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. This is normally done by adding an in-line terminator on the cable. Note. Use active (ANSI SCSI-2 Alternative 2) single-ended terminators when terminating a bus operating in singleended mode.
42 Cheetah 9LP Installation Guide, Rev. B 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. Pin 1 Pin 2 J2 RR S D MW P E E T ESEP DSS P Term.
