10.8 Terminator requirements Caution: These drives do not have onboard internal terminators. The user, systems integrator or host equipment manufacturer must provide a terminator arrangement external to the drive when termination is required. For LW drives, terminator modules can be purchased that plug between the SCSI I/O cable and the drive I/O connector or on the end of a short I/O cable stub extending past the last cable connector. LC drives are designed to be plugged into a backpanel connector without cabling. 10.9 Terminator power LW drives You can configure terminator power from the drive to the SCSI bus or have the host adaptor or other device supply terminator power to the external terminator. See Section 9.1 for illustrations that show how to place jumpers for this configuration. LC drives These drives cannot furnish terminator power because no conductors in the 80-pin I/O connector are devoted to terminator power. Cheetah 15K.5 SCSI Product Manual, Rev. J 71
