Remove controller canister

You remove the controller canister so you can replace the failed host interface card. When you remove a
controller canister, you must disconnect all cables. Then, you can slide the controller canister out of the
controller shelf.
Before you begin
• You have labels to identify each cable that is connected to the controller canister.
• You must have a #1 Phillips screwdriver.
• You have an ESD wristband, or you have taken other antistatic precautions.
• You have prepared a flat, static free work area.
Procedure
1. Label each cable that is attached to the controller canister.
2. Disconnect all the cables from the controller canister.
Attention: To prevent degraded performance, do not twist, fold, pinch, or step on the cables.
3. If the HIC ports use SFP+ transceivers, remove them.
Depending on what type of HIC you are upgrading to, you might be able to reuse these SFPs.
4. Confirm that the Cache Active LED on the back of the controller is off.
5. Squeeze the handles on either side of the controller, and pull back until it releases from the shelf.
