SENSATION!  (250-1651)  Installing A Expansion Adapter Faxback Doc. # 2738

Your computer has three open expansion slots in the three-slot area of the
computer.  You can install tow full-length adapters in the upper expansion
slots.  You can install a half-length ISA expansion adapter in the bottom
slot.

If you are installing an upgrade processor or additional memory, do so
before you install expansion adapters in he three-slot area.  Otherwise,
you will have to remove the adapters before installing SIMMs or an upgrade
processor.

If you prefer not to install adapters, your computer dealer can arrange to
have them installed for you.

INSTALLING AN EXPANSION ADAPTER IN THE THREE-SLOT AREA

The top two slots support full-length adapters.  the bottom slot supports
a half-length adapter (up to 8 inches).  If you will be performing other
installations or upgrades that require you to access jumpers or sockets on
the main logic board, complete them before installing adapters in the
three-slot area.

CAUTION:  Installing a longer adapter in the bottom slot can damage the
          adapter or the main logic board.

Read the expansion adapter documentation and follow these steps to install
an expansion adapter:

1.  Open the computer as described in "Opening and Closing the Computer."

2.  Remove the expansion slot screw and cover.  Save the slot cover in
    case you later remove the expansion adapter.

3.  Press the expansion adapter into the expansion slot connector on the
    riser card.  If you are installing a full-length adapter, be sure to
    correctly position it in the guide slot.

4.  Secure the expansion adapter bracket, using the screw you removed from
    the slot cover.

5.  Connect the expansion adapter cables (if any) as specified by the
    instructions provided with the adapter.

To route a cable between an expansion adapter in the three-slot expansion
area and a device in a drive bay, route the cable through the opening at
the top of the riser card.  Remove both drive supports as described in the
"System Disassembly" section.  Then, remove the chassis crossbar.

After routing the cable, reinstall the chassis crossbar and drive
supports.  Then attach the cable to the device.

6.  Be sure the internal cables are securely connected and do not cause
    mechanical interference.  Then, close the computer as described in
    "Opening and Closing the Computer."

7.  Reconnect all cables.

8.  Run the setup utility to enter any information that has changed due
    to installation of the expansion adapter.  Update the system
    worksheet.
