If you do not want any ac outlets installed on the front or rear ac outlet-mounting plate, perform only "Attaching the rack to the concrete floor beneath a raised floor" on page 9 through "Connecting the power distribution system" on page 13. For instructions to install front or rear ac outlet-mounting plates, see "Installing the ac outlet-mounting plates with ac outlets" on page 14. Connecting a dc power source: Some rack models (such as the 7014-T00) can support a dc power configuration for systems that require dc power. If you decide to connect a dc power source to the rack, you can use the procedure in this section to perform this task. This section also includes illustrations of the related hardware components and shows how these components relate to each other. Note: The customer is responsible for providing and connecting the -48 V dc power source and -48 V dc power return cables from the customer's source -48 V dc to the bus bars in the power distribution panel. The customer is also responsible for connecting the ground cable to the rack frame. This procedure provides information about accessing the power distribution panel. 1.
