3.2.2. Step 2: Remove failed controller

Remove a controller canister to replace the failed canister with a new one.

This is a multi-step procedure that requires you to remove the following components: battery, host

interface card, power supply, DIMMs, and fans.

Remove the failed controller canister so you can replace it with a new one.

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 controller canister has a HIC that uses SFP+ transceivers, remove the SFPs.

Because you must remove the HIC from the failed controller canister, you must remove any

SFPs from the HIC ports. When you reconnect the cables, you can move those SFPs to the

new controller canister.

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.
