Page 6: Overview
Overview The SDX-400V drive is a high-capacity data storage device using the Advanced Intelligent Tape (AIT) technology. The SDX-400V drive achieves high data reliability through Read-After-Write, an additional level of error correction code, and other features. The SDX-400V drive stores data on tape using standard formats called AIT (Advanced Intelligent Tape) and ALDC.

Page 17 Press down at an angle on each side in turn until you hear the hinge clips click into place. Caution Do not press the dust cover in horizontally from the front. Doing so could cause the dust cover to break. Close the dust cover.
Page 18: Removing The Dust Cover
Removing the Dust Cover Open the dust cover. Holding the dust cover at both corners, carefully raise the dust cover. The dust cover hinge clips and drive bezel pins uncouple. Note We recommend that you use the drive with the dust cover.

Drive Operation Loading a Cartridge Note While setting the data cartridge, do not turn off the host computer. This may cause a malfunction or damage data. Turn on the basic processing unit. Check that the drive’s TAPE MOTION LED, CLEANING REQUEST LED and REPLACE TAPE LED go off.
Page 21: Unloading A Cartridge
Unloading a Cartridge The cartridge can be removed from the SDX-400V either in response to a SCSI Unload Command, or by pressing the EJECT bottom. By pressing EJECT button, the tape goes to BOT, the drive unthreads it, and ejects the cartridge from the slot. Write-protecting a Cartridge Cartridges can be write-protected by sliding the tab on the back of the cartridge.
Page 22: Emergency Tape Removal Procedure
Emergency Tape Removal Procedure Remove the drive from the chassis or enclosure to allow access to the bottom of the drive. Remove the drive’s top cover. Locate the small opening in the bottom of the drive and insert the tip of a precision screwdriver so that the Loading motor shaft can be rotated.
Page 23 After the tape slack has been removed, continue to turn the Loading moter shaft located on the bottom of the drive clockwise by a precision screwdriver until the tape cartridge is lifted out of the drive mechanism and is ejected. Return the drive to Acer for repair.
