7. 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 117 for more information.
Note: You might have to reconfigure the disk arrays after you install hard disk drives. See the RAID
documentation on the Lenovo website at
adapters.
If you have other devices to install or remove, do so now. Otherwise, go to "Completing the installation" on
page 85.
Replacing a 3.5-inch hot-swap hard disk drive
Use this information to replace a 3.5-inch hot-swap hard disk drive.
Before replacing a 3.5-inch hot-swap hard disk drive, read the following information:
• Inspect the drive tray for signs of damage.
• To maintain proper system cooling, do not operate the server for more than 10 minutes without either a
drive or a filler panel installed in each drive bay.
• You do not have to turn off the server to install hot-swap drives in the hot-swap drive bays.
To replace a 3.5-inch hot-swap hard disk drive, complete the following steps.
1. Read the safety information that begins "Safety" on page v and "Installation guidelines" on page 169.
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 191).
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 205).
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.
