If you are instructed to return the component or optional device, follow all
packaging instructions, and use 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:
v Depending on the model, the compute node supports up to two 2.5-inch
SAS/SATA hard disk drives in the bays.
v For a list of supported optional devices for the server, see http://
www.ibm.com/systems/info/x86servers/serverproven/compat/us.
v Inspect the drive and drive bay for signs of damage.
v Make sure that the drive is correctly installed in the drive bay.
v See the documentation for the ServeRAID adapter for instructions for installing
a hard disk drive.
v 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.
v 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.
1. Read "Safety" on page vii and "Installation guidelines" on page 93.
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 96 for instructions).
3. Carefully lay the compute node on a flat, static-protective surface, orienting the
compute node with the bezel pointing toward you.
4. Remove the cover (see "Removing the compute node cover" on page 110).
5. Pull the plunger of the 2.5-inch hard disk drive cage outward and rotate the
cage upward.
