CAUTION:
Removing components from the upper positions in the rack cabinet improves
rack stability during a 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 observe the following precautions.
– 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 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 If the rack cabinet you are relocating was supplied with removable outriggers
they must be reinstalled before the cabinet is relocated.
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 230 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 10 degrees.
v When the rack cabinet is in the new location, complete the following steps:
– 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.

v Load the rack from the bottom up to ensure rack stability. Empty the rack from
the top down.
Important: The enclosure and battery modules are shipped separately. You must
install the battery modules after you install the enclosure in the rack.
