Safety Information
 Do not allow hair or objects near the ventilation slots.
z Because a Switch is equipped with internal cooling fan units, do not allow anything
near the ventilation slots. Doing so causes heat to accumulate inside the Switch and
could cause a failure. Do not allow hair or objects near the ventilation slots because
they might be sucked into the Switch, resulting in injury.
 When moving a Switch, do not hold the handle of optional modules.
z When moving a Switch, do not hold the handle of a fan unit or a power supply unit.
The handle might come off, resulting in the Switch falling and possibly causing injury.
Also, the fan unit or power supply unit might become deformed, resulting in fire or
electric shock.
 Disconnect the cables before moving a Switch.
z Before moving a Switch, you must turn it off and disconnect all cables. Failure to do
so might cause the Switch or cable to become deformed, or might damage the
Switch, resulting in fire or electric shock.
 Do not drop optional modules.
z Handle an optional module carefully. Dropping it could result in injury.
z The weight of a DC power supply unit is 5.6 kg and its front-to-back measurement is
163 mm. When removing a DC power supply unit from a Switch, hold the DC power
supply unit itself. If you pull the unit carelessly, it might fall, possibly resulting in
injury. The following label is attached to a DC power supply unit.
 Do not touch the inside of the Switch with your hands.
z Do not carelessly put your hands inside the Switch. The frame and components
might cause injury.
 When removing a management and switching unit or a network interface
unit, use care because it might be very hot.
z The components in a management and switching unit and a network interface unit
might be very hot. Do not touch any components with your hands. Doing so could
result in burns.
