2500 SX/25 (250-1610) Installing Additional Drives Faxback Doc. # 1129
Three storage devices can be installed in the drive bays. The two upper
bays support low-profile (maximum height, 1") 3 1/2" devices. The lower bay
supports a half-height 5 1/4" device or a standard 3 1/2" device.
* Install internal hard drives in the 3 1/2" bay, the 5 1/4" drive bay, or
the expansion adapter area. The SmartDrive (IDE hard drive) connector in
your computer supports up to two internal hard drives.
* Install diskette drives in the 3 1/2" or 5 1/4" drive bays.
* To removed the 3 1/2" panel, press down on the center tab from inside the
cover. This panel is not replaceable.
* To remove the 5 1/4" panel, press down on the panel from outside the
cover. This panel is not replaceable.
If you are installing a hard drive that is not a SmartDrive (IDE), you will
need to install an expansion adapter for the drive. Refer to the drive and
adapter documentation for instructions.
Some installations require additional mounting hardware. For example, you
might need to purchase a 3 1/2" to 5 1/4" disk drive adapter and L-bracket
to install some 3 1/2" drives in the 5 1/4" bay. Mounting hardware is
available at your computer dealer.
INSTALLING A 3 1/2" DISKETTE DRIVE
Use the following procedure to install a 3 1/2" diskette drive:
1. Open the computer to gain access to the 3 1/2" drive bay.
2. Select the appropriate mounting holes on the diskette drive.
3. Slide the drive into the 3 1/2" drive bay. With the drive resting on the
center rail, align the mounting holes on the side of the drive with the
two mounting holes on the side of the carriage.
4. Mount the diskette drive in the bay by installing the four screws as
illustrated. Remove the plastic card from the 5 1/4" bay. you must
insert the screwdriver through the hole in the 5 1/4" bay to install
one of the bottom screws.
5. Loosen the diskette drive cable connector from the cable attached to the
factory-installed diskette drive. Pin 1 of the connector is labeled.
Align Pin 1 of the cable connector with Pin 1 of the drive connector on
the back of the diskette drive. Then, attach the cable connector to the
connector.
6. Run the setup utility to complete the installation. Refer to "SETUPSX"
in the "Utilities" section for more information.
INSTALLING A 3 1/2" HARD DRIVE
Use the following procedure to install a 3 1/2" hard drive. Refer to the
drive installation guide for instructions on adjusting drive components,
connecting the drive cable, and selecting mounting holes on the drive. You
will also need information from the drive installation guide to run the
setup utility after installing the drive. Record this information on the
system worksheet at the end of this manual.
1. Open the computer to gain access to the 3 1/2" drive bay.
2. Select the appropriate mounting holes on the drive.
3. Slide the drive into the 3 1/2" drive bay. With the drive resting on the
center rail, align the mounting holes on the side of the drive with the
two mounting holes on the side of the carriage.
4. Mount the drive in the bay by installing the screws as illustrated.
5. Attach the remaining cable connector to the SmartDrive connector on the
main logic board. Attach a power cable from the computer power supply.
Refer to "Completing the SmartDrive Installation" for additional
instructions.
6. Run the setup utility to update your system configuration by identifying
the drive. Use the arrow keys to move the cursor into the hard disk
drive area and press the spacebar. The setup configuration screen
displays several drive descriptions. Select the drive description that
matches the information you recorded on the worksheet. If you do not
find an exact match, either choose "Any (non-standard hard disk)" and
enter the drive parameters or choose "AUTO" and the computer will
automatically determine the hard disk parameters. Efer to "SETUPSX" in
the "Utilities" section for more information.
CAUTION: After installing the hard drive, it might be necessary to park the
drive heads before opening the carriage or moving the computer. Refer to
the installation guide for this information.
INSTALLING A 5 1/4" DRIVE
Use the following procedure to install a 5 1/4" drive. Refer to the drive
documentation for further instructions.
NOTE: If you have a problem with the power connection not plugging in all
the way you will need to add a power extender cable (Cat.#278-767).
1. Open the computer to gain access to the 5 1/4" drive bay in the
carriage.
2. If you are installing a diskette drive, a tape drive, or a CD-ROM drive,
remove the plastic card from the bottom of the 5 1/4" bay and remove the
panel from the computer cover.
3. Select the appropriate mounting holes for the drive. Refer to your drive
installation guide.
4. Slide the drive into the bay. Align the appropriate mounting holes in
the drive with the three mounting holes on the bottom of the carriage.
5. Mount the drive in the bottom of the carriage, using the screws included
in your drive kit.
6. Connect the drive cable to the appropriate connector on the main logic
board. Connect one of the power cables from the computer power supply to
the power connector on the drive.
INSTALLING A 3 1/2" DRIVE IN THE 5 1/4" BAY
Refer to the drive installation guide for further instructions.
1. Open the computer to gain access to the 5 1/4" bay.
2. Install the drive in a 3 1/2" to 5 1/4" internal disk drive adapter
(25-1076). Refer to the Internal Disk Drive Adapter installation guide
for more information. Attach the drive cable to the device as directed.
3. Align the holes on the wider side of the L-bracket with the bottom set
of holes on the drive adapter. Install the screws.
4. Insert the drive, adapter, and L-bracket into the 5 1/4" bay. Use the
three screws from the installation kit to mount the device.
5. Attach the remaining cable connector to the appropriate connector on the
main logic board. Connect one of the power cables from the computer
power supply to the power connector on the drive.
COMPLETING THE SMARTDRIVE INSTALLATION
A SmartDrive (IDE hard disk drive) is a hard disk drive with a built-in
controller. Because a hard disk controller usually occupies an expansion
slot, using a SmartDrive frees an expansion slot for some other use and
saves you the cost of a separate controller, providing maximum performance
and guaranteed compatibility at a lower cost than other drive/controller
combinations.
To install a SmartDrive:
* Install the drive as described in "Installing a 3 1/2" Hard Drive". To
install a 3 1/2" SmartDrive in the 5 1/4" bay, use the mounting holes on
the bottom of the drive. Refer to "Installing a 3 1/2" Drive in the
5 1/4" Bay" for instructions.
* Connect a SmartDrive data/controller cable between the SmartDrive and the
40-pin SmartDrive connector on the main logic board. The data/controller
cable supports up to two SmartDrives. The SmartDrive cable and connector
are keyed to ensure that they connect properly.
* Connect a power cable from the power supply to the power connector on the
hard drive.
To connect an unkeyed IDE cable, align Pin 1 of the cable connector with
Pin 1 of the main logic board connector and then press the cable connector
onto the main logic board connector. Some cables have a stripe on one side.
This stripe indicates Pin 1 one the cable connector. On the main logic
board, a dot number 1 is printed next to Pin 1 of the main logic board
connector.
After installing a SmartDrive (or any hard disk drive), run the setup
utility to update your system configuration.
