Removing a 3.5-inch hot-swap hard disk drive
Use this information to remove a 3.5-inch hot-swap hard disk drive.
Before removing 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 remove 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 163.
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 and remove 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 185).
4. Remove the filler panel, if one is present.
5. Push the orange release latch of the drive tray and take the 3.5-inch hard disk drive out of the drive
bay of the server.
6. Replace the filler panel into the empty drive bay.
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
.
