The site AC input voltage is routed to each PDU mounted in the rack. Each PDU distributes AC
through ten receptacles directly to the storage system components.
•
PDUs 1 and 3 (optional) are mounted on the left side of the cabinet. Power cords connect
these PDUs to the number 1 drive enclosure power supplies and to the controller enclosures.
•
PDUs 2 and 4 (optional) are mounted on the right side of the cabinet. Power cords connect
these PDUs to the number 2 drive enclosure power supplies and to the controller enclosures.
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.
Moving the rack requires a clear, uncarpeted pathway that is at least 80 cm (31.5 in) wide for
the 60.3 cm (23.7 in) wide, 42U rack. A vertical clearance of 203.2 cm (80 in) should ensure
sufficient clearance for the 200 cm (78.7 in) high, 42U rack.
CAUTION:
Ensure that no vertical or horizontal restrictions exist that would prevent rack movement
without damaging the rack.
Make sure that all four leveler feet are in the fully raised position. This process will ensure that the
casters support the rack weight and the feet do not impede movement.
Each rack requires an area 600 mm (23.62 in) wide and 1000 mm (39.37 in) deep (see
Figure 30 (page 63)
).

If the feet are not fully raised, complete the following procedure:
1.
Raise one foot by turning the leveler foot hex nut counterclockwise until the weight of the rack
is fully on the caster (see
Figure 31 (page 64)
).
