DR550 Rack relocation
CAUTION:
Follow these general guidelines whenever a populated rack cabinet is relocated
within a room or building:
v
If the rack cabinet that is being relocating is part of a suite of rack cabinets,
detach the rack cabinet from the suite.
v Inspect the route that you plan to take when moving the rack to eliminate
potential hazards.
v
Verify that the route that you choose can support the weight of the loaded
rack cabinet. Refer to the documentation that came with your rack cabinet for
the weight of a loaded rack cabinet.
v
Verify that all door openings are at least 760 x 2030 mm (30 x 80 in.).
v
Ensure that all devices, shelves, drawers, doors, and cables are secure.
v
Ensure that the four leveling pads are raised to their highest position.
v
Ensure that there is no stabilizer bracket installed on the rack cabinet during
movement.
v
Do not use a ramp inclined at more than ten degrees.
v Once the rack cabinet is in the new location, do the following:
– Lower the four leveling pads.
– Install stabilizer brackets on the rack cabinet.
v
If a long distance relocation is required, restore the rack cabinet to the
configuration of the rack cabinet as you received it. Pack the rack cabinet in
the original packaging material, or equivalent. Also, lower the leveling pads
to raise the casters off of the pallet and bolt the rack cabinet to the pallet.
Safety inspections
Perform the following safety checks to identify unsafe conditions. Be cautious of
potential safety hazards that are not covered in the safety checks. If unsafe
conditions are present, determine how serious the hazards are and whether you
