IBM System x3300 M4 Installation And Service Manual page 365

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.
2. Unlock the left-side cover.
Note: You must unlock the left-side cover to open or remove the bezel. When
you lock the left-side cover, it locks both the cover and the bezel.
3. Open the bezel (see "Removing the bezel" on page 331).
4. Remove the existing 3.5-inch hot-swap hard disk drive (see "Removing a
3.5-inch hot-swap hard disk drive" on page 345).
5. Touch the static-protective package that contains the 3.5-inch hot-swap hard
disk drive; then, remove the 3.5-inch hot-swap hard disk drive from the
package.
6. Make sure that the tray handle is open; then, install the hard disk drive into
the hot-swap bay.
7. Align the drive assembly with the guide rails in the bay; then, carefully slide
the drive assembly into the drive bay until the drive snaps into place.
8. Rotate the drive tray handle to the closed position.
9. Check the hard disk drive status indicator to make sure that the hard disk
drive is operating correctly.
After you replace a failed hard disk drive, the green activity LED flashes as
the disk spins up. The yellow LED turns off after approximately 1 minute. If
the new drive starts to rebuild, the yellow LED flashes slowly, and the green
activity LED remains lit during the rebuild process. If the yellow LED remains
lit, seeChapter 4, "Troubleshooting," on page 139 for more information.
Note: You might have to re-configure the disk arrays after you install hard
disk drives. See the RAID documentation on the IBM website at
http://www.ibm.com/systems/support/ for information about RAID
adapters.
