A customer has ordered a rack， a p650， two p630s， and two p615s. During a conversation on installation planning， the pSeries technical specialist recognizes that the customer expects the rack to arrive as one unit. However， the specialist knows that the p650 will be racked， but the other systems will arrive separately. In fact， the other systems are CSU （Customer Set Up）. Why should the specialist immediately inform the customer that additional racking is the customer’s responsibility？（）A、Because additional systems would require more power receptaclesB、Because the customer may need to do additional facilities planningC、Because the customer needs additional funding to cover the servicesD、Because postponing the eventual discussion will likely lead to customer dissatisfaction
