Note: Use any documentation that comes with the RAID 110i upgrade key and follow those instructions in

To install the RAID 110i upgrade key, do the following:
Attention: Installing the RAID 110i upgrade key might impact your RAID configurations. Back up your data
before you begin to avoid any data loss due to a RAID configuration change.
1. Remove all external media from the drives and turn off all attached devices and the server. Then,
disconnect all power cords from electrical outlets and disconnect all cables that are connected to
the server.
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. Remove the cooling shroud. See "Removing the cooling shroud" on page 75.
5. Touch the static-protective package that contains the RAID 110i upgrade key to any unpainted surface
on the outside of the server. Then, take the RAID 110i upgrade key out of the package.
