and above.
– Ensure that the heaviest devices are installed in the bottom of the rack cabinet.
xviii Dell EMC ML3 Tape Library: User's Guide
– Ensure that there are little-to-no empty U-levels between devices installed in the rack-cabinet below
the 32U (compliance ID RACK-001) or 22U (compliance ID RR001) level, unless the received
configuration specifically allowed it.
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 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, complete these 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. (R002)

Notes:
v1A single module (or the lowest module in a library) can have a 4-slot I/O Station. The lowest slot is inaccessible
to the accessor.
v2HH = Half height. FH = Full height.
v3Every module except the lowest one can contain a 5-slot I/O Station. If a seven Module library has an I/O
Station for each module, the maximum number of slots that can be configured as I/O slots are 34 (six modules
with 5-slot I/O Stations, and the lowest module with a 4-slot I/O Station).

Supported library configurations
The library supports a single base module tabletop configuration or a scalable rackmount configuration.
All libraries start with a Base Module. Up to six Expansion Modules can be added as needed to support
customer requirements. The architecture is designed to support a maximum of three Expansion Modules
above the Base Module and three Expansion Modules below the Base Module. Table 5 on page 3 shows
the supported configurations for libraries, ranging 1 - 7 total modules.
