Remove the host interface card
You remove the original host interface card (HIC) so you can replace it with an upgraded one.
Before you begin
• You have a #1 Phillips screwdriver.
• You have an ESD wristband, or you have taken other antistatic precautions.
Steps
1. Remove the controller canister's cover by unscrewing the single thumbscrew and lifting the lid
open.
2.
Confirm that the green LED inside the controller 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.
3.
Using a Phillips screwdriver, remove the two screws that attach the HIC faceplate to the
controller canister.
Note: The image above is an example, the appearance of your HIC may differ.
