Remove a host interface card

You remove the original host interface card (HIC) so you can replace it with an upgraded one.

1. Remove the controller canister's cover by pressing down on the button and sliding the cover off.
2. Confirm that the green LED inside the controller (between the battery and the DIMMs) is off.
   If this green LED is on, the controller is still using battery power. You must wait for this LED to go off before removing any components.

   There are four screws: one on the top, one on the side, and two on the front.
