Contributors NetAppZacharyWambold netapp-jolieg

You need to remove the controller canister from the controller shelf, so you can remove the battery.

When you remove a controller canister, you must disconnect all cables. Then, you can slide the controller canister out of the controller shelf.

What you’ll need
  • An ESD wristband, or you have taken other antistatic precautions.

  • Labels to identify each cable that is connected to the controller canister.

Steps
  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.

    Caution To prevent degraded performance, do not twist, fold, pinch, or step on the cables.
  4. If the host ports on the controller canister use SFP+ transceivers, leave them installed.

  5. Confirm that the Cache Active LED on the back of the controller is off.

  6. Squeeze the latch on the cam handle until it releases, and then open the cam handle to the right to release the controller canister from the shelf.

    Caution Always use two hands to support the weight of a controller canister.

    If you are removing the controller canister from an E2812 controller shelf, E2824 controller shelf or EF280 flash array, a flap swings into place to block the empty bay, helping to maintain air flow and cooling.

  8. Turn the controller canister over, so that the removable cover faces up.

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