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.

    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.

    The following figure is an example of a DE2000H/DE4000H (2U12) controller shelf, DE2000H/DE4000H (2U24) controller shelf, or DE4000F flash array:

    28 dwg de2000h de4000h 2u24 remove controller canister maint de2000h de4000h

    (1) Controller canister

    (2) Cam handle

    The following figure is an example of a DE4000H (4U60) controller shelf:

    28 dwg de4000h 4u60 add controller canister maint de2000h de4000h

    (1) Controller canister

    (2) Cam handle

  7. Using two hands and the cam handle, slide the controller canister out of the shelf.

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

    If you are removing the controller canister from a DE2000H/DE4000H (2U12) controller shelf, DE2000H/DE4000H (2U24) controller shelf or DE4000F 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.

  10. Go to Remove failed DE2000H or DE4000H battery.
