Terminator requirements

Caution: These drives do not have onboard internal terminators. The user, systems integrator or host equip-

ment 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.

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 8.1 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.
