Installing or replacing a hot-swap hard disk drive
Attention: Do not open your server or attempt any repair before reading and understanding “Safety information”
on page iii and “Guidelines” on page 61.
You can install or replace a hot-swap hard disk drive without turning off the server, which helps you avoid
significant interruption to the operation of the system.
For a list of the ThinkServer hard disk drive options, go to:
The EMI integrity and cooling of the server are protected by having all drive bays covered or occupied. The
number of the installed hard disk drives in your server varies depending on the server model. The vacant
bays are occupied by dummy hard-disk-drive trays. When you install a hot-swap hard disk drive, save the
removed dummy hard-disk-drive tray from the drive bay in case that you later remove the hot-swap hard
disk 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 hot-swap hard disk drive as soon as you remove the failing one or
the dummy tray.
Before you begin, review the following hard disk drive installation rules:
• Follow the order of the hard-disk-drive bays when installing a hard disk drive. See “Front view of the
server” on page 17 to locate the hard-disk-drive bays in your server.
• For RAID configuration, the hard disk drives must be the same type with the same capacity if they are
within a single RAID array. For more information, see “Configuring RAID” on page 56.
• For hard disk drives with different capacities, install the hard disk drive by following the order of the
hard-disk-drive bays as well as the order from the lowest capacity to the highest capacity.
Before you begin, print all the related instructions or ensure that you can view the PDF version on another
computer for reference.
Notes:
• Depending on the model, your server might come with 3.5-inch hot-swap hard disk drives or 2.5-inch
hot-swap hard disk drives. The illustrations in this topic are based on server models with 3.5-inch
hot-swap hard disk drives. For other models, the replacement procedure is similar.
• Use any documentation that comes with the hot-swap hard disk drive and follow those instructions in
addition to the instructions in this topic.
To install or replace a hot-swap hard disk drive, do the following:
1. Locate the appropriate hard-disk-drive bay. See “Front view of the server” on page 17.
