The image above is an example; the appearance of your HIC may differ.
7. Place the HIC on a flat, static-free surface.

7.3.4. Step 4: Replace the HIC

After removing the old HIC, install a new HIC.
Possible loss of data access — Never install a HIC in a DE6400 or DE6600
controller canister if that HIC was designed for another DE-Series controller. In

addition, if you have a duplex configuration, both controllers and both HICs must
be identical. The presence of incompatible or mismatched HICs causes the
controllers to lock down when you apply power.
Steps
1. Unpack the new HIC and the new HIC faceplate.
2. Align the single thumbscrew on the HIC with the corresponding holes on the controller, and
align the connector on the bottom of the HIC with the HIC interface connector on the controller
card.
Be careful not to scratch or bump the components on the bottom of the HIC or on the top of
the controller card.
3. Carefully lower the HIC into place, and seat the HIC connector by pressing gently on the HIC.

Possible equipment damage — Be very careful not to pinch the gold ribbon
connector for the controller LEDs between the HIC and the thumbscrew.
