SCSI Connectors
Use the SCSI connectors to connect external SCSI devices such as DDS-for-
mat tape drives and CD-ROM drives. Consult the documentation that
accompanies each SCSI device for specific information concerning its use.
Refer to Appendix C of this manual for information about connecting SCSI
devices to your workstation.
NOTICE: There must ALWAYS be a terminator at both ends of a SCSI bus. This
means one internal terminator and one external terminator. Both the Fast-
Wide SCSI and Single-Ended SCSI connectors must have a terminator
connected when no external device is connected. Note that the fast, wide
terminators and the single-ended terminators are different and not
interchangeable.
WARNING: The C200/C240 workstations have an Ultra Wide-SE SCSI interface in place of
the Fast-Wide SCSI interface. These interfaces are not compatible. Connecting
a Fast-Wide device to an Ultra Wide-SE interface will not work and may
damage the device. Be sure to connect only Fast-Wide devices to a Fast-Wide
interface and Ultra Wide-SE devices to an Ultra Wide-SE interface.
TOC Button
The TOC button resets the system and transfers control from the default
device to an auxiliary device.
Power Cord Connector
Plug the workstation’s power cord into the power cord connector to provide
ac power to the system.
