Channel 0 Channel 1 Getting Started I/O Interface Card The I/O Interface card provides the connection from the subsystem’s bus to the host adapter. Located on the I/O Interface card are two 68-pin very high density (VHD) SCSI connectors. The connectors are labeled Channel 0 and Channel 1. The I/O Interface card incorporates built-in automatic SCSI termination. When a data cable is plugged in, the system automatically senses the connection and provides the required SCSI termination. T

Getting Started Configuration Modules CAUTION: Configuration modules must be installed or replaced by qualified service personnel only. The CR8e’s SCSI bus design provides either of two bus configurations which is determined by the configuration module installed. The Dual-Bus module provides a split bus configuration where the enclosure’s top four drive slots and the lower four drive slots are on two independent SCSI buses. The Single-Bus module connects both SCSI buses together tying all
