Dell T3400 manual Installing an Optional Third Hard Drive Tower Computer, 199

10If you are removing a hard drive that has a metal shield, and are not going to install a replacement drive in the drive bay, reinstall the shield in the empty bay (see "About Metal Shields (Present in Some Drive Configurations)" on page 188). Then, install a drive-panel insert (see "Installing a Drive-Panel Insert" on page 218).

Installing an Optional Third Hard Drive (Tower Computer)

NOTICE: Do not attempt to install a SAS hard drive in the lower 3.5-inch drive bay. This drive bay will only support a floppy drive or a Media Card Reader.

1Follow the procedures in "Before You Begin" on page 143.

2Remove the computer cover (see "Removing the Computer Cover" on page 145).

3If you are installing a new drive, unpack the drive and prepare it for installation.

Check the documentation for the drive to verify that it is configured for your computer.

NOTE: Drive-panel inserts may contain screws on the inside. You can attach the screws to new drives that do not have any screws.

4If you are installing a new drive, remove the drive panel (see "Removing the Drive Panel (Tower Computer)" on page 213) and the drive-panel insert (see "Removing a Drive-Panel Insert" on page 218) from the upper 3.5-inch drive bay. Use the screws provided with the new drive to install the drive into the drive bay.

5If the FlexBay is not populated and metal shields are present in your computer (see "About Metal Shields (Present in Some Drive Configurations)" on page 188), remove the vented metal insert:

a Pull the vented metal insert forward until its surface is flush with that of the surrounding chassis.

b Rotate the bottom of the metal insert up towards you, disengaging its lower screws from the surrounding metal.

c Lift the metal insert from the computer, disengaging its top screws and metal tabs from the surrounding metal.
