Systems are not rack-ready , it is recommended an order to allow the hot addition for expansion shelves in future. As below:
In steps 1, 2, 3, and 4 in the example, establish the first expansion shelf at the bottom of each shelf set based on the system capacity, positioning them in the rack according the diagram shipped with the specific system. This establishes the full range of space in the racks required for future expansion of capacity as needs require.
It also allows for easy installation of additional shelves into any shelf set, with a simple process of installing the shelf and re-cabling so that the B side cable from the controller is connected to the host port on the new shelf at the end of the chain. Interconnect cables are also added between the two shelves.
