About the Metal Shields Present in Some Drive Configurations
In certain computer configurations, metal shields are present in the drive bays of your computer. If metal shields are present in your computer configuration,
they are essential and must be installed in the appropriate bays at all times.
Note that if a metal shield is installed over a hard drive, and you install an optical drive in its place, a shield is not needed in that bay. In this situation, the
metal shield should be kept in case it is needed later.
If you remove a hard drive, optical drive, media card reader, or floppy drive from your computer, you will need to install a metal shield in its place. If a metal
shield is not installed in any of these cases, your computer may not function properly. Contact Dell if you need an extra shield (see
Contacting Dell ).
Removing and Replacing the FlexBay Metal Shield
To remove a metal shield from the lower Flexbay:
Slide the sliding-plate lever to the right and hold it in place as you pull to remove the vented metal insert from the FlexBay.
To replace a metal shield over the lower drive bays:
a. Align the metal insert's two upper screws and its two lower screws with the corresponding slots inside the FlexBay.
b. Push the vented metal insert until it clicks into place and its metal tabs rest flush against the chassis surface.
