6. Remove the RAID 510i upgrade key from the Lenovo ThinkServer RAID 510i AnyRAID Adapter.
Note: If necessary, remove the Lenovo ThinkServer RAID 510i AnyRAID Adapter first for easier

7. Reinstall any parts and reconnect any cables that you have removed.
8. If you are instructed to return the old RAID 510i 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 164. Because the
hardware RAID 5 and 50 levels are not available without the RAID 510i 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 DVD that comes with your server.
