Installing a 1.8-inch hard disk drive

Use this information to install a 1.8-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 four 1.8-inch SAS/SATA hard disk drives in the bays.
• For a list of supported optional devices for the server, see Lenovo ServerProven compatability.
• 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 1.8-inch hard disk drive, complete the following steps.

1. Read Safety and Installation guidelines.
2. If the compute node is installed in an Lenovo NeXtScale n1200 Enclosure, remove it (see Removing a compute node from a chassis 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).
5. Pull the plunger of the 1.8-inch hard disk drive cage outward and rotate the cage upward.

6. Remove the filler panel, if one is present.
7. Touch the static-protective package that contains the disk drive to any unpainted metal surface on the server; then, remove the disk drive from the package.
8. Make sure that the tray handle is open; then, carefully slide the drive into the drive bay until the drive snaps into place.

   Note

   1. 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.
   2. 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 for instructions).
2. Install the compute node into the chassis (see Installing a compute node in a chassis for instructions).
