Do not place the Switch in an unstable location.
• When installing the Switch on a table, position the Switch horizontally on a worktable
strong enough to bear the weight of the Switch. Placing the Switch in an unstable location,
such as on an unsteady or tilting surface, might cause the Switch to fall, resulting in injury.
• When mounting the Switch in a rack, make sure that the Switch is stable. If the Switch is
unstable, it might fall, resulting in injury.
Do not open the Switch cover.
• Do not open the Switch cover. Doing so could result in electric shock. The following label
is attached to a Switch.
Do not obstruct the ventilation slots.
• Do not obstruct the ventilation slots of the Switch. Doing so causes heat to accumulate
inside the Switch, and could result in a fire. Maintain a space of at least 50 mm around the
ventilation slots.
Do not allow hair or objects near the ventilation slots.
• Cooling fan units are mounted in the Switch. 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 other objects near the ventilation slots. They might be sucked into the
Switch, resulting in injury.
When moving the Switch, do not hold the handle of the power supply unit,
fan unit, or power supply module.
• When moving a redundant power model, do not hold the handle of a power supply unit or
a fan unit. The handle might come off, resulting in the device falling and possibly causing
injury. Also, the power supply module might become damaged, resulting in a fire or
electric shock.
• Do not hold the handle of the power supply module when moving an EPU. The handle
might come off, resulting in the device falling and possibly causing injury. Also, the power
supply module might become damaged, resulting in a fire or electric shock.
When moving a Switch
• Before moving a Switch, you must turn it off and unplug 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.
