Installing or replacing a hot-swap hard disk drive
Attention: Do not open your server or attempt any repair before reading and understanding the “Safety information”
on page iii and “Guidelines” on page 83.
This topic provides instructions on how to install or replace a hot-swap hard disk drive.
This topic applies only to server models that have hot-swap hard disk drive(s) installed. See “Features” on
page 7 for more information about the supported hot-swap hard disk drives.
For a list of the ThinkServer hard disk drive options, go to http://www.lenovo.com/thinkserver. Click the
Products tab and then click Options ➙ ThinkServer Hard Drives to view the information.
You can install or replace a hot-swap hard disk drive without turning off the server, which helps you avoid
signicant interruption to the operation of the system.
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 either covered by an EMI-protective panel or 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 the
event 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, consider the following hard disk drive installation rules:
• Follow the order of the hard disk drive bays when installing a hard disk drive. See “Server components”
on page 25 to locate the hard disk drive bays in your server.
• For RAID conguration, 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 “Conguring RAID” on page 71
.
• For hard disk drives with different capacities, install the hard disk drive with the lowest capacity rst.
Before you begin, print all the related instructions or ensure that you can view the PDF version on another
computer for reference.
Notes:
1. Depending on the model, your server might come with 3.5-inch hot-swap hard disk drive(s) or 2.5-inch
hot-swap hard disk drive(s). The illustrations in this topic are based on server models with four 3.5-inch
hot-swap SATA or SAS hard disk drives. For other models, the replacement procedure is the same.
2. Depending on the model, your server might look slightly different from the illustrations in this topic.
