Reconnect the data cables and cluster cables to the rear of the
controller, as required.
If the cable management arm (CMA) is in the way, extend the controller
approximately 13 cm (5 inches) out of the front of the rack.
Reconnect the power cables to the power supplies and secure them with the
reclosable straps as shown in the following figure.
If necessary, reinstall the cables into the CMA and secure them with the
reclosable cable straps.
If you pulled the controller out of the rack to make it easier to connect the
cables, push the controller into the rack until the slide-rail locks (on the
front of the controller) engage the slide-rail assemblies.
You will hear an audible click when the controller is in the normal rack
position.
