Note: NVMe drive bays can accept either SATA/SAS or NVMe drives.
Step 1. Determine the drive type that you can install in the bay (SATA/SAS or NVMe) based on labels
stenciled on the front of the server and any drive bay labels that might have been applied to the
front of the server. These labels correspond to the drive backplane types that are installed. The
drive type must match the drive bay type. Drive type information is available on the package that
contains the drive.
Step 2. Install the hard disk drive in the drive bay.
If the server is operating (turned on), the green activity LED on the hard disk drive should light solid,
indicating that the drive is receiving power.

a. Open the drive handle, align the drive with the drive bay, and insert the drive.
b. Push the drive into the bay until the drive stops; then, rotate drive handle closed to fully seat
the drive and lock it in place.
Step 3. Check the hard disk drive status LED to verify that the hard disk drive is operating correctly.
• If the yellow hard disk drive status LED of a drive is lit continuously, that drive is faulty and must
be replaced.
