Before you install a drive:
1.
Check to see if the system unit cover has a panel
covering the bay you want to use.
2.
If a panel covers the bay, remove the system unit
cover. For cover removal instructions, see page 81.
3.
Locate the panel latches on the inside of the cover.
Then squeeze the latches and push the panel out.
If you ever want to replace the panel, push it onto
the opening until you hear the latches click.
