Bull 32X SCSI-2 CD-ROM Drive, Инструкция по установке и использованию

Страница: 18 / 41

To set a SCSI address, you install jumpers onto pin positions 1, 2, or 3, located on the
jumper block, to set each position to
Onor Off. (See Table 2.) To set a position to On,
insert a jumper onto both the top and bottom pins. To set a position to Off, insert the
jumper onto the top pin only.
Note: Jumpers are also installed in other positions on the jumper block to enable or
disable other functions.
Refer to “Rear View and Jumper Pin Positions on the 32X SCSI-2 CD-ROM Drive” on
page 7 and to Table 2 as you go through the following steps to set the SCSI address on
this drive:
Attention: Be sure to read “Handling Static-Sensitive Devices” on page vii before you
begin.
1. Remove the drive from its bag.
2. Place the drive on top of the bag on a flat surface.
3. Refer to “Rear View and Jumper Pin Positions on the 32X SCSI-2 CD-ROM Drive”
on page 7. Locate pin positions 1, 2, and 3 on the drive. They are the first three
positions on the left side of the jumper block as you view the drive from the back.
The SCSI address is factory-set to 5.
4. Using Table 2 as your guide, install jumpers in the correct positions to set the SCSI
address you previously chose.
Table 2. SCSI Address Settings
SCSI Address Position 1 Position 3 Position 3
0 Off Off Off
1 On Off Off
2 Off On Off
3 On On Off
4 Off Off On
5 On Off On
6 Off On On
5. Make sure the jumper on position 4 is set to On. This position enables proper parity.
6. The jumper in position 5 should be set to Off. This sets the default sector size of the
drive to 2K bytes. (Setting this position to On would make the default sector size
512 bytes.)
7. Make sure the jumper in position 6 is set to Off. Because this position does not
enable or disable any function, you can use it as a spare jumper.
8. The jumper in position 7 should be set to Off. Because this position does not enable
or disable any function, you can use it as a spare jumper.
You can remove spare jumpers and store them in a safe place or install them in the Off
position on any unused pin position.
