OPTICAL DISK DRIVE OPTION
•
Elsag Bailey Part Number - L700794_1.
The IIOIS12 console supports an optional optical disk drive. To
install the drive you must install the SCSI terminator on the
rear of the drive, and then connect the drive to the Adaptec
SCSI controller. See Figure
for the location of the Adaptec
SCSI controller. See also
for card location in differ-
ent PCs. The controller does not require modifying. An external
SCSI cable is supplied with the unit in order to connect it to
the controller. The OIS12 system software must now be config-
ured to recognize the optical disk drive. Refer to the Configura-
tion manual for the steps necessary to have the OIS12
recognize the optical disk drive.
Recent versions of IIOIS12 consoles do not include the Adaptec
1540CF SCSI controller as shown in Figure
and
Instead, an Adaptec 2940 SCSI controller is used with the
optical disk drive. Install this card in an available PCI card
slot. See
for the BIOS setup instructions for the
2940 controller.
NOTE: Set the drive's SCSI ID address to two. See the optical disk
drive's setup manual on how to select the SCSI ID address. The rest
of the settings should remain at their default.
Important things to remember when you are using an optical
disk drive:
•
The drive
must
be turned on and there
must
be a disk car-
tridge in the drive whenever the OIS12 console is started
up, otherwise the optical disk drive will not be recognized
as a valid drive.
•
DO NOT “WARM BOOT”
the OIS12 console when the opti-
cal drive is in use.
BOOT THE OIS12 CONSOLE USING
THE POWER SWITCH
. Failure to do so sometimes leaves
the optical disk drive in a strange state, so that the drive is
not recognized when the computer restarts.
