Lenovo x3300 M4 7382 Installation And Service Manual page 214

• The server supports one optional ultra-slim SATA CD-RW/DVD-ROM optical drive.
• The server can support up to eight 2.5-inch hot-swap SAS/SATA drives, four 3.5-inch hot-swap SAS/
SATA drives, or four 3.5-inch simple-swap SATA drives.
• You can mix hot-swap SAS and SATA hard disk drives in the same server as long as you do not mix drives
on the same array.
• The electromagnetic interference (EMI) integrity and cooling of the server are protected by having all bays
and PCI Express slots covered or occupied. When you install a drive, save the EMC shield and filler panel
from the bay in the event that you later remove the device.
Removing a 2.5-inch hot-swap hard disk drive
Use this information to remove a 2.5-inch hot-swap hard disk drive.
The following notes describe the types of hard disk drives that the server supports and other information that
you must consider when you install a hard disk drive:
• Depending on the model, the server supports up to eight or up to sixteen 2.5-inch SAS/SATA hot-swap
hard disk drives in the hot-swap bays.
Note: When using ServeRAID adapter M1015 to support more than sixteen 2.5-inch hard disk drives, the
maximum number of RAID supported drives is 16. All the other drives will remain JBOD (the drives are
presented to the operating system without a RAID configuration).
• For a list of supported optional devices for the server, see
• Inspect the drive and drive bay for signs of damage.
• Make sure that the drive is correctly installed in the drive bay.
• See the documentation for the ServeRAID adapter for instructions for installing a hard disk drive.
• All hot-swap drives in the server must have the same throughput speed rating; using drives with different
speed ratings might cause all drives to operate at the speed of the slowest drive.
• You do not have to turn off the server to install hot-swap drives in the hot-swap drive bays. However, you
must turn off the server when you perform any steps that involve installing or removing cables.
To remove a 2.5-inch hot-swap hard disk drive, complete the following steps:
1. Read the safety information that begins "Safety" on page v and "Installation guidelines" on page 169.
Attention: Static electricity that is released to internal server components when the server is powered-
on might cause the server to halt, which might result in the loss of data. To avoid this potential problem,
always use an electrostatic-discharge wrist strap or other grounding system when you work inside the
server with the power on.
2. Unlock the left-side cover.
Note: You must unlock the left-side cover to open or remove the bezel. When you lock the left-side
cover, it locks both the cover and the bezel.
3. Open the bezel (see "Removing the bezel" on page 191).
4. Remove the filler panel, if one is present.
5. Touch the static-protective package that contains the disk drive to any unpainted metal surface on the
server; then, remove the disk drive from the package.
6. Make sure that the tray handle is open; then, remove the 2.5-inch hard disk drive out of the hot-swap
bay.
