CAUTION:
Removing components from the upper positions in the rack cabinet improves rack stability
during relocation. Follow these general guidelines whenever you relocate a populated rack
cabinet within a room or building:
v Reduce the weight of the rack cabinet by removing equipment, starting at the top of the
rack cabinet. When possible, restore the rack cabinet to the configuration of the rack
cabinet as you received it. If this configuration is not known, you must do the following
steps.
– Remove all devices in the 32U position and above.
– Ensure that the heaviest devices are installed in the bottom of the rack cabinet.
– Ensure that there are no empty U-levels between devices that are installed in the rack
cabinet below the 32U level.
v If the rack cabinet you are 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 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 comes with your rack cabinet for the weight of a loaded
rack cabinet.
v Verify that all door openings are at least 760 x 2032 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 no stabilizer bracket is installed on the rack cabinet during movement.
v Do not use a ramp that is inclined at more than 10 degrees.
v When the rack cabinet is in the new location:
– Lower the four leveling pads.
– Install stabilizer brackets on the rack cabinet.
– If you removed any devices from the rack cabinet, repopulate the rack cabinet from the
lowest position to the highest position.
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 the pallet and bolt the
rack cabinet to the pallet.
