4.2.1.
Powering up the SDX-700C
After the initial installation of the SDX-700C 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-700C will execute a power-up diagnostic and
then comes ready.
Once the tape has been loaded the SDX-700C 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)
Inserting Cassettes
4.2.2.
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-700C performs a tape load sequence as described in
clause 4.3.1
Removing Cassettes
4.2.3.
The cassette can be removed from the SDX-700C 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
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.
