Extending the Controller from the Rack

Use the following procedure to extend the storage controller from the rack. If you cannot extend the controller without removing power, first see Powering Off the Controller.

1. To prevent the rack from tipping forward when the controller is extended, extend all rack anti-tilt mechanisms.
2. Verify that no cables will be damaged or will interfere when the controller is extended.

   Although controller cable management arms (CMAs) are hinged to accommodate extending the controller, you should ensure that all cables and cords are capable of extending. If necessary, label and disconnect cables that are not capable of extending, including cluster cables for clustered controllers.

3. From the front of the storage controller, release the two slide release latches.

   Depending on the controller, either squeeze the latches inward or pull them forward.

4. While holding the slide release latches, slowly pull the storage controller forward until the slide rails latch.
