2.5-inch drive replacement from 3.5-inch drive bay
Use this information to remove and install a 2.5-inch drive from a 3.5-inch drive bay.
The EMI integrity and cooling of the server are protected by having all drive bays covered or occupied. The
number of the installed drives in your server varies depending on the server model. The vacant bays are
occupied by dummy trays. When you install a drive, save the removed dummy tray from the drive bay in case
you later remove the drive and need the dummy tray to cover the place.
