• 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 144. As the
hardware RAID 5 and 50 levels are not available without the RAID 510i key, you might need to reconfigure
RAID for your server. Refer to the MegaRAID SAS Software User Guide on the documentation DVD that
comes with your server for information about how to configure the hardware RAID.
