Remove controller canister

You remove the controller canister so you can add the new 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

Procedure

  1. Put on an ESD wristband or take other antistatic precautions.
  2. Label each cable that is attached to the controller canister.
  3. Disconnect all the cables from the controller canister.
    Attention: To prevent degraded performance, do not twist, fold, pinch, or step on the cables.
  4. If the HIC ports use SFP+ transceivers, remove them.

    Depending on what type of HIC you are adding to, you might be able to reuse these SFPs.

  5. Confirm that the Cache Active LED on the back of the controller is off.
  6. Squeeze the handles on either side of the controller, and pull back until it releases from the shelf.

  7. Using two hands and the handles, slide the controller canister out of the shelf. When the front of the controller is free of the enclosure, use two hands to pull it out completely.
    Attention: Always use two hands to support the weight of a controller canister.


  8. Place the controller canister on a flat, static-free surface.

After you finish

Go to Add the new host interface card.
