Many of the answers in this section mention SCSI cabling and termination, but what are some other items to consider?
A11. Check for damaged jumpers that are used to specify SCSI identification or to enable/disable SCSI device features, also make absolutely sure the jumpers are the correct size – 2mm and 0.10″ are visually similar but are not compatible; refer to photos in the Appendix. Check power connectors, make sure the metal to metal connections are not loose. Check for short circuits between system chassis and SCSI cable caused by small breaks in the insulation. Try to test the SCSI device on another “known good” system if one is available. Once in a while the SCSI device itself has a malfunction. Refer to Appendix A, section A1.7.
