If the module is difficult to remove, gently ease the module back and forth to remove it from the connector. If the new floppy drive does not include shoulder screws, use the screws within the drive panel insert. If the DDR2 memory modules are not installed in matched pairs, the computer will continue to operate, but with a slight reduction in performance. If you are not installing a processor upgrade kit from Dell, reuse the original heat-sink assembly when you install your new processor. If you are installing a new drive, you need to remove the drive-panel insert. Do not route card cables over or behind the cards.

When you install the heat-sink assembly, do not touch the thermal interface on its underside, as this may result in damage to the thermal interface material. To guard against electrical shock, be sure to unplug your computer from its electrical outlet cimension installing any cards. The mounting-bracket screws need to be removed for the removal of the system board. If the new floppy drive does not include shoulder screws, ee510 the screws within the drive panel insert.
You must route these cables properly when you replace them to prevent them from being pinched or crimped. When you install a filler bracket, ensure that the bracket is seated correctly. Only unbuffered, non-ECC memory is supported.
When you connect an IDE interface cable, do not place the colored stripe away from pin 1 of the connector. Instead, set the drive on a surface, such as a foam pad, that will sufficiently cushion it. See the drive documentation xell your upgrade kit for information on configuring devices for the cable select setting.
To avoid damage to the memory module, press the module straight down into the connector while you apply equal force to each end of the module. If the DDR2 memory modules are not installed in matched pairs, the computer will continue to operate, but with a slight reduction in performance.
If your computer includes a card retention mechanism, remove the top of the retention mechanism by pressing the tab and pulling up on the top.
To avoid damage, ensure that the processor aligns properly with the socket, and do not use excessive force when you install the processor.
Installing filler brackets over empty card-slot openings is necessary to maintain FCC certification of the computer. The pin-1 end of a connector on a board or a card is usually indicated by a silk-screened “1” printed directly on the board or dimenskon.
See the label on the module to determine the module’s capacity. When removing e501 replacing the processor, lci not touch any of the pins inside the processor socket or allow any objects to fall onto the pins in the socket. If you are installing a processor upgrade kit from Dell, discard the original heat-sink assembly. To connect a network cable, first plug the cable into the network port or device and then plug it into the computer.
If you insert the module correctly, the securing clips snap into the cutouts at each end of the module. After you remove the heat-sink assembly, lay the assembly on its side.
Reversing the cable prevents the drive from operating and could damage the controller, the drive, or both. Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide. Note the routing of the DC power cables underneath the routing clips in the computer frame as you remove them from the system board and drives.
If you are installing or replacing a PCI Express card, follow the procedures in the next section.
If you are installing a new drive, you need to remove the drive-panel insert. Ground yourself by touching an unpainted metal surface on the back of the computer. Do not route card cables over or behind dsll cards.
When installing the heat-sink assembly, do not touch the thermal interface on its underside, as this may result in damage.

Most interface connectors are keyed for correct insertion; that is, a notch or a missing pin on one connector matches a tab or a filled-in hole on the other connector. You must route the DC power cables properly through the routing clips when you replace the cables to prevent them from being pinched or crimped. Leave the release lever extended in the release position so that the socket is ready for the new processor.
Any address space reserved for these components cannot be used by computer memory. You can do so by touching an unpainted metal surface on the computer chassis.
