SCSI Tips for MMR/MMP Users We have found that the quality of materials and attention to detail in setting up external SCSI devices for use with the MMR/MMP system can have a profound effect on the reliability and performance of the system. This document provides details on some of the issues that have been found to impact a successful and trouble-free installation. SCSI Cables There is a considerable difference in quality and performance of cables used to connect SCSI devices.
SCSI Termination A terminator provides electrical circuitry at the end of a SCSI chain to prevent the reflection of electrical signals when they reach the end of the chain. The SCSI bus requires terminations only at the ends of the SCSI chain, not in the middle. There are several types of SCSI Termination: Passive, Active, Active Negation, Force Perfect Termination, and Low Voltage Differential. The MMR/MMP should only use Active terminators.
Wide SCSI Cards and Kingston Frames The MMR/MMP are normally shipped with a narrow Symbios SCSI card. The MMR/MMP units also support the Symbios SYM8751SP Wide SCSI card. To install a wide SCSI card, use a grounding strap and follow the installation instructions below: Removing the Narrow Host Adapter (Symbios SYM 8600SP) 1) 3) Disconnect the 26-pin ribbon cable from J2 on the MMR Biphase Operations Board, and fold out of the way.
