SCSI bus termination Cheetah 18LP Installation Guide, Rev. C 3. 21 Configure termination power. Terminators have to get power from some source. The default configuration results in the drive not suppling termination power to the bus. You should normally leave this drive set at this default unless your host system requires that the drive supply termination power to the bus. To configure this drive to supply termination power to the bus, place a jumper on J2 pins 1 and 2 as shown in the figure below. J2 RR S D MW P E E T ESEP DSS P Term.

This step is optional because the drive will work fine without an LED connected, but many people find this to be helpful to determine when the drive is actively reading or writing data. Most host systems provide this LED which is a small "bulb" (actually a light-emitting diode) located on the host's front panel. Simply locate this LED and connect the attached pair of wires to the pins on the drive as shown in Figure 6 below. Drive Front Jumper Plug (enlarged to show detail) J6 Pin 1 Reserved Activity LED Reserved The shaded pins are shipped with a cover installed. Retain the cover unless you install a 20-pin plug. CATH Note: On some LEDs the flat side of indicator is cathode. Figure 6. Drive Active LED indicator connections Cheetah 18LP Installation Guide, Rev. C 5. 23 Check the other available jumper settings (optional) This drive provides several features for unique configurations. You will not normally need to change from the default settings for normal operation. Single-ended mode option You can force the drive to operate only in SE mode by installing a jumper on J2 pins 15 and 16. The default is to allow the drive to automatically detect and use SE or LVD mode. See page 11 for a description of these two modes. Delay Motor Start and Motor Start options You can control when the drive's motor starts spinning the media using these two jumper positions (J2 pins 11 and 12 and J2 pins 13 and 14). You can configure the drive to delay spinning up until a certain number of seconds elapse or until the drive receives a Start Unit command from the host system. The default settings are with both off so that the drive begins spinning up as soon as it receives power. Write Protect option You can install a jumper connecting J2 pins 9 and 10 to prevent anyone from writing data to this disc drive (users can still read data from the drive). This jumper is normally left off to allow users to write data to the drive.
