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.

Moving and stabilizing a rack

WARNING!

The physical size and weight of the rack requires a minimum of two people to move.

If one person tries to move the rack, injury may occur.

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.
