Removing and Replacing Front-Panel Inserts
Empty drive bays contain a front-panel insert to protect the inside of the computer from dust particles and also to ensure proper airflow within the
computer. Before you install a drive in an empty drive bay, you must first remove the front-panel insert.
To remove the insert covering a 5.25-inch bay, perform the following steps:
1. Turn off the system, including any attached peripherals, and disconnect all the AC power cables from their electrical outlets.
2. Remove the computer cover.
3. Remove the front bezel.
4. With your thumbs, press in on each end of the insert until the insert snaps free of the bezel on the chassis (see Figure 3).
