4.2.1.Powering up the SDX-800V

After the initial installation of the SDX-800V has been verified, power can be applied to the unit. The +12V and +5V power must be applied simultaneously. (See Figure 2-5) The SDX-800V will execute a power-up diagnostic and then comes ready.

Once the tape has been loaded the SDX-800V sends a CHECK CONDITION response on receipt of the next SCSI command from the host. The UNIT ATTENTION key is set in the returned REQUEST SENSE data to indicate that the tape may have been changed. (Sense Key/ASC/ASCQ = 06/28/00)

4.2.2.Inserting Cassettes

The operator inserts a cassette into the slot on the front panel. As the cassette is inserted, the drive takes it and automatically loads it into the drive mechanism. The SDX-800V performs a tape load sequence as described in clause 4.3.1

4.2.3.Removing Cassettes

The cassette can be removed from the SDX-800V either in response to a SCSI UNLOAD command, or by pressing the Eject button. The operator uses the Eject button to initiate the unload sequence (see clause 4.3.2). The mechanism winds the tape to Beginning of Media (BOM), unthreads it, and ejects the cassette from the slot.

Operation of the Eject button is disabled if the host has previously sent a SCSI PREVENT ALLOW MEDIA REMOVAL command with prevent bit set to one. In this case, pressing the Eject button has no effect, and does not initiate an Unload sequence. The Eject button returns to normal operation following receipt of an PREVENT ALLOW MEDIA REMOVAL command with prevent bit clear.

4.2.4.Hard Reset Hole

Hard reset hole

In case of emergency, you can immediately reset the drive itself by pushing the switch in the “Hard Reset Hole” with the tip of a pin. However, there is a risk of losing data upon execution of this operation in the Write or Read mode. The hardware reset operation is only for manufacturing and repair purposes.

4.2.5.Write-Protecting Cassettes

Cassettes can be write-protected by sliding the tab on the back of the cassette open. In this state, data can be read from the tape but not written to it.

Caution: The Tape Log, which contains a history of usage of the tape, will not be updated when the cassette is write-protected. It follows that the Tape Log becomes inaccurate if a cassette is used write-protected, and the media warning cannot be relied on to indicate that the cassette needs to be copied and replaced.
