INSTALLATION OVERVIEW

When installing internal options, be sure to:

*  Remove and replace the computer cover as directed.
*  Check the configuration of the serial or parallel adapter if you are
   connecting a serial or parallel device.
*  Run the Setup utility to complete the installation of drives, memory,
   serial/parallel adapters, or video expansion adapters.

When installing expansion adapters, be sure that:

*  The metal slot cover on the expansion adapter is seated correctly
   in the back panel slot.
*  The fastening screw is securely tightened.
*  The front end of the expansion adapter fits into the corresponding
   plastic expansion adapter guide (long expansion adapters only).
*  The expansion adapter is securely mounted in the expansion adapter
   slot.

REMOVING THE COVER

You must remove the cover to install internal options.  Before removing
the cover, turn the computer off and disconnect all electrical cables
from the computer.

WARNING!  Be sure the computer is in a safe work area before you remove
the cover.

To remove the cover:

1.  If necessary, use the keylock key to unlock the cover.
2.  Remove the 3 cover mounting screws from the back of the computer.
3.  Slide the cover toward the front of the computer until it clears the
    base of the computer.
4.  Lift the lid of the computer off.

REPLACING COVER

Replace the cover after installing options.  Never operate the computer
while it is open.  To replace the cover:
1.  Carefully place the computer cover on the computer.
2.  Slide the cover toward the back of the computer until it fits into
    place.
3.  Replace and tighten the 3 cover mounting screws from the back of
    the computer.
4.  Lock the cover, if necessary.
5.  Connect the peripheral and power cables.

Normally, 3.5 inch drives are installed on the drive platform.  You can
also install 3.5 inch drives in the drive tower, using a 5.25 inch
adapter.

After installing a new drive, run the Setup utility to update the system
configuration as recorded in the CMOS RAM.

INSTALLING A 3.5 INCH DRIVE
Note:  If you are installing a 3.5 inch drive in a 5.25 inch drive, bay,
use a 5.25 inch mounting adapter.

1.  Adjust the selector switches and terminating resistors on the drives
    as necessary.  See the drive installation guide for more information.
2.  Remove the plastic insert from the front of the computer cover.
3.  Select the appropriate mounting holes for your drive.  See the drive
    installation guide for more information.  Mount the drive on the drive
    platform, using the screws provided with the computer.  Then, mount
    the drive platform in the computer.
4.  Connect the drive power and data cables.  See the drive installation
    for more information.

INSTALLING A 5.25 INCH DRIVE

1.  Adjust the selector switches and terminating resistors on the drives
    as necessary.  See the drive installation guide for more information.

2.  Remove the appropriate plastic panel from the computer cover.

Note:  The upper panel is held in place by tow screws and can be replaced
later if necessary.  The lower panel breaks away and is not replaceable.

3.  Remove the drive rails from the selected drive slot by pressing the
    drive rail latch tabs toward each other and sliding the rails out of
    the tower.

    To remove an installed drive, disconnect the drive cables and unlatch
    the drive by pressing the rail tabs toward each other.  Then, pull on
    the drive to remove it from the tower.

4.  Check to be sure a metal grounding clip is attached to each rail.
    Then, using the appropriate holes, mount the rails onto the sides of
    the drive.  The grounding clips must be present to ground the system.
