● When moving the equipment by hand, wear protective gloves to prevent
injuries.
● Move or lift the equipment by holding its handles or lower edges. Do not hold
the handles of modules (such as power supply units, fans, and boards) that
are installed in the equipment because they cannot support the weight of the
equipment.
● Avoid scratching the cabinet surface or damaging cabinet components and
cables during equipment transportation.
● When transporting the equipment using a forklift truck, ensure that the forks
are properly positioned to ensure that the equipment does not topple. Before
moving the equipment, secure it to the forklift truck using ropes. When
