Safety - 4
Ground the Switch.
 Always use a grounded outlet. Failure to do so might not only result in electric shock,
but it might also introduce unwanted electrical noise that could cause a Switch failure.
Handle power cables carefully.
 Do not place anything heavy on a power cable. Do not pull, bend, or modify a cable.
Doing so could damage the cable, resulting in a fire or electric shock. If the power
cable is covered by a carpet, it is easy to forget that the cable is there and to place
something heavy on it.
 Do not use any power cables other than those included with or specified for the
AX2200S or AX1250S series switch. Using another power cable could result in a fire
or electric shock. Do not use the supplied power cable for any device. Doing so could
result in a fire or electric shock.
 The AC power supply cable included with the AX1240S series is for use only with the
Switch. It cannot be used with any other device. Using the power cable with another
device is very dangerous and could result in fire or electric shock.
 When using the switch at 200 V AC, use a power cable that satisfies the specified
specifications. Using another power cable could result in a fire or electric shock.
 If the power cable is damaged so that the wires underneath the covering are visible or
cut, stop using it, and ask maintenance personnel to replace it. Discontinue using the
cable to avoid the risk of a fire or electric shock.
 Make sure the power plug is free of dust, and insert the plug completely up to the
base of the prongs, so that it is not loose. Using a power plug with dust on it or one
that is imperfectly connected could result in a fire or electric shock.
 Do not touch the power plug with a wet hand. Doing so could result in electric shock.
Do not overload the power outlet.
 Do not overload the power outlet by connecting multiple power plugs to the same
outlet. Overloading the outlet could result in fire or the circuit breaker tripping due to
excessive power used, which can then affect other equipment.
Do not use an air duster near a flame.
 When cleaning the optical connectors, do not use an air duster that contains
flammable gas near a flame. Doing so could result in a fire.
