2. If the server is installed in a rack cabinet, remove the server from the rack cabinet and place it on a flat,
clean, and static-protective surface. See the
Rack Installation Instructions
that comes with the server. If
the server is in tower form factor, lay the server on its side for easier operation.
3. Remove the server cover. See “Removing the server cover” on page 72.
4. Locate the RAID upgrade key that you want to remove. Then, remove the RAID upgrade key from the
RAID 510i AnyRAID adapter or the RAID 520i PCIe adapter.
Note:
If necessary, remove the RAID 510i AnyRAID adapter or the RAID 520i PCIe adapter first for
easier operation. After you remove the upgrade key, reinstall the adapter. See “Replacing the AnyRAID
adapter” on page 159 or “Installing or removing a PCIe card” on page 90.

5. If you are instructed to return the old RAID upgrade key, follow all packaging instructions and use any
packaging materials that are supplied to you for shipping.
What to do next:
• To work with another piece of hardware, go to the appropriate section.
• To complete the removal procedure, go to “Completing the parts replacement” on page 180. Because
the hardware RAID 5 and 50 levels are not available without the RAID upgrade key, you might need to
reconfigure RAID for your server. For information about how to configure the hardware RAID, refer to the
MegaRAID SAS Software User Guide
on the documentation disc that comes with your server.
