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.

SFPs from the HIC ports. However, you can leave any SFPs installed in the baseboard host
ports. When you reconnect the cables, you can move those SFPs to the new controller canister.
