Step 2.  Ensure that the drive tray handle is in the open position. Align the drive with the guide rails in the 
bay; then, gently push the drive into the bay until the drive stops.
Step 3.  Rotate the drive handle to the fully closed position to lock the drive in place.

After this task is completed
1.  If you have additional drives to install, do so now; if any of the drive bays is left empty, fill it with a drive 
bay filler.
2.  Complete the parts replacement. See “Complete the parts replacement” on page 217.
3.  Check the drive activity LED to verify that the drive is operating correctly. See “Front panel” on page 19
for details.
4.  If the server is configured for RAID operation through a ThinkSystem RAID adapter, you might have to 
reconfigure your disk arrays after you install drives. See the ThinkSystem RAID adapter documentation 
for additional information about RAID operation and complete instructions for using ThinkSystem RAID 
adapter.
2.5-inch drive replacement from 3.5-inch drive bay
Follow instructions in this section 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 simple-swap disk 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.
Attention: An unoccupied drive bay without any other protection might impact the EMI integrity and cooling 
of the server, which might result in overheating or component damage. To maintain the EMI integrity and 
cooling of the server, install a new drive as soon as you remove the failing one or the dummy tray.
Before you begin, review the following drive installation rules: 
•  Follow the order of the disk drive bays when installing a drive. See Chapter 2 “Server components” on 
page 15 to locate the disk drive bays in your server.
