About this task
Attention: 
•  Read the 
“Installation guidelines” on page 61 to ensure that you work safely.
•  Touch the static-protective package that contains the component to any unpainted metal surface on the 
server; then, remove it from the package and place it on a static-protective surface.
•  To avoid damage to the drive connectors, make sure that the server top cover is in place and fully closed 
whenever you install or remove a hot-swap drive.
•  To make sure that there is adequate system cooling, do not operate the server for more than two minutes 
without either a drive or a filler installed in each bay.
•  Before you remove or make changes to drives, drive controllers (including controllers that are integrated 
on the system board), drive backplanes or drive cables, back up all important data that is stored on drives.
•  Before you remove any component of a RAID array (drive, RAID card, etc.), back up all RAID configuration 
information.
The following notes describe the type of drives that your server supports and other information that you must 
consider when you install a drive.
•  Locate the documentation that comes with the drive and follow those instructions in addition to the 
instructions in this chapter.
•  Depending on your server models, your server supports the following drive types: 
–  Up to sixteen 2.5-inch hot-swap SATA/SAS drives
–  Up to eight 3.5-inch hot-swap SATA/SAS drives
–  Up to four 3.5-inch hot-swap SATA/SAS drives and eight 2.5-inch hot-swap SATA/SAS drives
•  For a complete list of supported drives and optional devices for the server, see: 
https://static.lenovo.com/ 
us/en/serverproven/index.shtml
•  The drive bays are numbered to indicate the installation order (starting from number “0”). Follow the 
installation order when you install a drive. See “Front view” on page 15.
•  The drives in a single RAID array must be the same type, same size, and same capacity.
