Rack AC power distribution The power distribution in a rack is the same for all variants. The site AC input voltage is routed to the dual PDU assembly mounted in the bottom rear of the rack. Each PDU distributes AC to a maximum of four PDMs mounted in pairs on the left vertical rail (see Figure 14 (page 33)). • PDMs 1-1 through 1-4 connect to receptacles A through D on PDU A. Power cords connect these PDMs to the left power supplies on the disk enclosures (disk PS 1) and to the left power supply on the controller enclosure (controller PS 1). • PDMs 2-1 through 2-4 connect to receptacles A through D on PDU B. Power cords connect these PDMs to the right power supplies on the disk enclosures (disk PS 2) and to the right power supply on the controller enclosure (controller PS 2). NOTE: The locations of the PDUs and the PDMs are the same in all racks. Figure 14 Rack AC power distribution 1. PDU 1 2. PDM 1-1 3. PDM 1-2 4. PDM 1-3 5. PDM 1-4 Moving and stabilizing a rack 6.

To ensure stability of the rack, always push on the lower half of the rack. Be especially careful when moving the rack over any bump (e.g., door sills, ramp edges, carpet edges, or elevator openings). When the rack is moved over a bump, there is a potential for it to tip over. Moving and stabilizing a rack 33
