Do not place the Switch in a place where it is unstable.
 If placing the Switch on a desk, lay it on its side on a workbench capable of
withstanding the weight of the Switch. If, for example, you place the Switch on a
shaky table or a tilted surface, the Switch might fall and possibly injure someone.
 When installing the Switch in a rack, make sure the Switch in the rack is stably
positioned. If the Switch is not positioned correctly, injury could result from falling
equipment or stumbling over the equipment.
Do not position the Switch vertically or lean it against a wall
 When installing the Switch on a table, position the Switch horizontally. If the switch is
positioned vertically or leaned against a wall, the switch might fall, which could result
in injury or damage.
Do not allow hair or objects near the ventilation slots
 The AX2230S-24P, AX1240S-24P2C, and AX1240S-48T2C is equipped with internal
cooling fan units. Do not allow hair or other objects near the ventilation slots, because
they might be sucked into the Switch, resulting in injury.
When moving the Switch
 Before moving the Switch, you must turn it off and unplug all cables. Failure to do so
might cause the Switch or cable to become damaged, resulting in a fire or electric
shock.
 If you must stack multiple switches during transport, use appropriate packaging.
Failure to do so might cause the Switch to become deformed or might damage the
Switch, resulting in fire or electric shock.
Handle the power cable carefully.
 Do not place the power cable near a heat-generating apparatus. The heat could melt
the cable coating, resulting in fire or electric shock.
 When connecting or disconnecting the AC power cable from the outlet, always hold
the plug, not the cable itself. Pulling the cable itself might cause the wires to break.
