a. After you install the hard disk drive, check the disk drive status LEDs to
verify that the hard disk drive is operating correctly. If the yellow hard disk
drive status LED is lit continuously, that drive is faulty and must be
replaced. If the green hard disk drive activity LED is flashing, the drive is
being accessed.
b. If the server is configured for RAID operation through an optional
ServeRAID adapter, you might have to reconfigure your disk arrays after
you install hard disk drives. See the ServeRAID documentation on the IBM
ServeRAID Support CD for additional information about RAID operation and
complete instructions for using ServeRAID manager.
After you install the hard disk drive backplate, complete the following steps:
1. Install the cover onto the compute node (see "Installing the compute node
cover" on page 111 for instructions).
2. Install the compute node into the chassis (see "Installing a compute node in a
chassis" on page 97 for instructions).
Removing a 1.8-inch hard disk drive
Use this information to remove a 1.8-inch hard disk drive.
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 remove a 1.8-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 1.8-inch hard disk drive cage outward and rotate the
cage upward.

6. Push the release latch inward to open the drive handle; then, pull the drive out
of the drive bay.
