[. . . ] Make sure all cables are properly secured. You can install up to seven devices to each SCSI channel, but each DAT Autochanger may represent more than one SCSI device. Host Computer DAT Autochanger SCSI Interface Cable Terminator Connecting the DAT Autochanger 13 Note When counting SCSI devices, keep in mind that a DAT Autochanger can contain up to two devices (the DAT drive and the robotics). Don't forget to include in your count other devices on the SCSI channel, (i. e. , a tape unit, an additional hard drive, etc. ). Each DAT Autochanger unit contains more than one SCSI device and may require more than one SCSI ID (depending on the mode of operation). The first chart below shows the different DAT Autochanger configurations and the number of SCSI IDs required. The second chart illustrates how many DAT Autochanger units you can attach to one SCSI channel (if there are no other devices on the channel). Number of SCSI IDs Required Sequential Mode 1 Random Mode 2 Maximum DAT Autochangers on one SCSI Channel Sequential Mode 7 Random Mode 3 Powering on the System p Plug the AC power cord into the connector on the rear of the DAT Autochanger. p Plug the AC power cord from the DAT Autochanger into a grounded electrical outlet. p Plug the AC power cord from your host computer into a grounded electrical outlet. Turn on the host computer power. 14 Connecting the DAT Autochanger Installing the Backup Software Note This is the software that operates the DAT Autochanger, not the data being transferred to the DAT Autochanger cassettes. Two examples of backup software are Cheyenne's ARCserve and Legato's Networker. Refer to the installation instructions provided with your backup software and install the software on your host computer. After you have completed installation of the DAT Autochanger and the software, you should run any diagnostic test(s) supplied with the software to make sure your unit is operating correctly.

Just turn on the power switch, place a magazine on the carriage and press the LOAD button on the front panel. Front Panel Switches and Indicators Switches and indicators on the front of the DAT Autochanger are shown in the following illustration. 18 Equipment Description Power LED (green) Busy LED (green) Lights when the power is on. It also reports error conditions (through a blinking sequence). It also reports error conditions (through a blinking sequence in conjunction with the Power LED). Note The Power and Busy LEDs are used to indicate that an error has occurred with the DAT Autochanger. Refer to Chapter 5, Troubleshooting and Diagnostics for descriptions of the error codes displayed by the Power and Busy LEDs. Locked LED (green) Lights whenever the LOAD and UNLOAD buttons are disabled. This occurs when a cassette is in the drive, or if commanded from the system software. This LED blinks when an unload operation is pending in sequential access mode. [. . . ] A host computer system that requests an operation to be performed by a target device.
