(For sliding drawers.) Do not pull out or install any drawer or
feature if the rack stabilizer brackets are not attached to the rack.

become unstable if you pull out more than one drawer at a time.
(For fixed drawers.) This drawer is a fixed drawer and should not
be moved for servicing unless specified by manufacturer.

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:
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:
• 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.
If the rack cabinet you are relocating is part of a suite of rack
cabinets, detach the rack cabinet from the suite.
Inspect the route that you plan to take to eliminate potential
hazards.
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.
Verify that all door openings are at least 760 x 230 mm (30 x 80
in.).
