PRODUCT OVERVIEW

PRODUCT OVERVIEWPRODUCT OVERVIEW

Quantum’s Fireball Plus AS hard disk drives are part of a family of high
performance, 1-inch-high hard disk drives manufactured to meet the highest
product quality standards.

These hard disk drives use nonremovable, 3 1/2-inch hard disks and are
available with the ATA interface.

The Quantum Fireball Plus AS 10.2/20.5/30.0/40.0/60.0 GB AT hard disk drives
feature an embedded hard disk drive controller, and use ATA commands to
optimize system performance. Because the drive manages media defects and error
recovery internally, these operations are fully transparent to the user.

The configuration of the following Three jumpers controls the drive’s five modes
of operation:

•CS – Cable Select

• DS – Drive Select

•PK– Jumper Parking Position (Slave mode)

• AC– Alternate Capacity

The AT PCB has two jumper locatio ns provided to configure t he drive in a system.
The default configuration for the drive as shipped from the factory is with a
jumper across the DS location, and open positions in the CS, PK and AC
positions.

Table 3-1 defines the operation of the master/slave jumpers and their function
relative to pin 28 on the interface. 1 indicates that the specified jumper is installed;
0 indicates that the jumper is not installed.

When a Quantum Fireball Plus AS 10.2/20.5/30.0/40.0/60.0 GB AT hard disk
drive and another ATA hard disk drive are daisy-chained together, they can be
configured as Master or Slave either by the CS or DS jumpers. To configure the
drive as a Master or Slav e with the CS feature, the CS jumper is in stalled (1). Th e
drive's position on the 80 conductor Ultra ATA data cable then determines
whether the drive is a Master (Device 0) or a Slave (Device 1). If the drive is
connected to the end of the Ultra (cable Select) data cable the drive is a Master.
If the drive is connected to the middle connection it is set as a Slave.

jumper setting does not matter.

Once you install the C S jumper, the driv e is configured as a Ma ster or Slave by t he
state of the Cable Sele ct signal: pin 28 of the ATA bus conne ctor. Please no te that
pin 28 is a vendor-specific pin that Quantum is using for a specific purpose. More
than one function is allocated to CS, according to the ATA CAM specification
(see reference to this specification in Chapter 1). If pin 28 is a 0 (grounded), the

drive is configured as a Master. If it is a 1 (high), the drive is configured as a Slave.
In order to configure two drives in a Master/Slave relationship using the CS
jumper, you need to use a cable that provides the proper signal level at pin 28 of
the ATA bus connector. This allows two drives to operate in a Master/Slave
relationship according to the drive cable placement.

The Quantum Fireball Plus AS 10.2/20.5/30.0/40.0/60.0 GB AT hard disk drives
are shipped from the f actory as a Master (Device 0 - CS jumper installed). To
configure a drive as a Slave (Device 1- DS scheme), the CS jumper must be
removed. In this configuration, the spare jumper removed from the CS position
may be stored on the PK jumper pins.

ATA BUS ADAPTER

ATA BUS ADAPTERATA BUS ADAPTER

There are two ways you can configure a system to allow the Quantum Fireball Plus
AS hard disk drives to communicate over the ATA bus of an IBM or IBM­compatible PC:

1. Connect the drive to a 40-pin ATA bus connector (if available) on the

motherboard of the PC.

2. Install an IDE-compatible adapter board in the PC, and connect the drive

to the adapter board.

40-Pin ATA Bus Connector

40-Pin ATA Bus Connector40-Pin ATA Bus Connector

Most PC motherboards have a built-in 40-pin ATA bus connector that is
compatible with the 40-pin ATA interface of the Quantum Fireball Plus AS 10.2/

20.5/30.0/40.0/60.0 GB AT hard disk drives. If the motherboard has an ATA
connector, simply connect a 40-pin ribbon cable between the drive and the
motherboard.

You should also refer to the moth erboard instruction manual, and refer to Chapt er
6 of this manual to ensure signal compatibility.

Adapter Board

Adapter BoardAdapter Board

If your PC motherboard does not contain a built-in 40-pin ATA bus interface
connector, you must install an ATA bus adapter board and connecting cable to
allow the drive t o interface with the mo therboard. Quantum does not supply such
an adapter board, but they are available from several third-party vendors.

Please carefully read the instruction manual that comes with your adapter board,
as well as Chapter 6 of this manual to ensure signal compatibility between the
adapter board and the drive. Also, make sure that the adapter board jumper
settings are appropriate.

the drive. The drive can also be mounted using the four mounting hole locations
on the PCB side of the drive.

Note: It is highly recommended that the drive is hard mounted on to

the chassis of the system being used for general operation, as
well as for test purposes. Failure to hard mount the drive can
result in erroneous errors during testing.

hard disk drives in an AT-compatible system that contains a 40-pin ATA bus
connector on the motherboard.

To connect the drive to the motherboard, use a 40 conductor ribbon cable (80

shorter. Ensure that pin 1 of the drive is connected to pin 1 of the motherboard

disk drive in an AT-compatible system without a 40-pin ATA bus connector on its
motherboard, you need a third-party IDE-compatible adapter board.

Adapter Board Installation

Adapter Board InstallationAdapter Board Installation

Carefully read the manual that accompanies your adapter board before installing
it. Make sure that all the jumpers are set p roperly and th at there are no add ress or
signal conflicts. You must also investigate to see if your AT-compatible system
contains a combination floppy and hard disk controller board. If it does, you must
disable the hard disk drive controller functions on that controller board before
proceeding.

Installation

Once you have disabled the hard disk drive controller functions on the floppy/
hard drive controller, install the adapter board. Again, make sure that you have
set all jumper straps on the adapter board to avoid addressing and signal conflicts.

Note: For Sections 3.7 and 3.8, power should be turned off on the

computer before installing the drive.
