Adding a controller

To add a controller:

1. Verify that the new controller is configured properly, and a device driver is installed that can support the new controller. See ``Preparing to add or replace a controller''.

2. Physically insert the controller into the slot, and connect the cable(s).

3. Lock the interlock for the slot (if it has one).

   The Hot Plug Manager displays an locked interlock indicator (closed padlock).

4. Select the slot that contains the new controller (click on the slot icon).

5. Turn power on for the slot. See ``Turning slot power on''.

   NOTE: Some controllers take time to initialize after they have been powered-on. You might have to wait until the controller is fully initialized before proceeding to the next step. If the controller fails to initialize properly the slot automatically powers-off.

6. Choose one of the following:

   • If you are replacing a controller, suspend the driver instance for the old controller (see ``Suspending a driver instance'') and move the cable(s) from the old controller to the new one. If you replaced the controller with an identical new controller (or one that is supported by the same device driver), resume the suspended driver instance onto the new controller (see ``Resuming a driver instance'' ). Otherwise, add a driver for the new controller (see ``Adding a new driver'' ).

   • If you are adding (not replacing) a controller, add a driver. See ``Adding a new driver''.
