- If the rack cabinet that you are relocating is part of a suite of rack cabinets, detach the rack cabinet from the suite.

- 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.
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.
