any packaging materials for shipping that are supplied to you.
Installing a 2.5-inch hard disk drive
Use this information to install a 2.5-inch 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 compute node supports up to two 2.5-inch SAS/SATA hard disk drives
in the bays.
• For a list of supported optional devices for the server, see
http://www.ibm.com/systems/info/x86servers/serverproven/compat/us.
• 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 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 must turn off the compute node when you perform any steps that involve installing or removing cables.
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.
To install a 2.5-inch hard disk drive, complete the following steps.
Step 1. Read "Safety" on page v and "Installation guidelines" on page 89.
Step 2. If the compute node is installed in an IBM NeXtScale n1200 Enclosure, remove it (see "Removing
a compute node from a chassis" on page 92 for instructions).
Step 3. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node
with the bezel pointing toward you.
Step 4. Remove the cover (see "Removing the compute node cover" on page 105).
Step 5. Pull the plunger of the 2.5-inch hard disk drive cage outward and rotate the cage upward.
