Reinstall controller canister

You reinstall the controller canister into the controller shelf after installing the new host interface card (HIC).

1. Reinstall the cover on the controller canister by sliding the cover from back to front until the button clicks.
2. Turn the controller canister over, so that the removable cover faces down.
3. With the cam handle in the open position, slide the controller canister all the way into the controller shelf.
   The following figures are examples of a 2U and 4U controller shelf:

4. Move the cam handle to the left to lock the controller canister in place.
5. Reconnect all the cables you removed.
   Attention: Do not connect data cables to the new HIC ports at this time.
6. (Optional) If you are upgrading HICs in a two-controller configuration, repeat all steps to remove the other controller canister, remove the HIC, install the new HIC, and replace the second controller canister.
