The hard disk drive side door of the server is unlocked when shipped from the factory. You can open the side
door to view the hot-swap hard disk drive LED status, install a new hard disk drive, and remove or replace a
failing hard disk drive. However, you can also lock the hard disk drive side door to ensure that all the hard
disk drives cannot be accessed unless you remove the server cover. If you do so, you must turn off the
server, disconnect all power cords, and remove the server cover when you want to replace any hard disk
drives, including the hot-swap hard disk drives.
To lock or unlock the hard disk drive side door, do the following:
1. Press the blue button 1 to open the side door.
