Do not place the Switch in a high-temperature location.
 Do not place the Switch in direct sunlight or near a heater or other heat-generating
apparatus. Doing so could adversely affect parts of the Switch.
Do not use a TV or a radio near the Switch.
 Placing the Switch near a TV or a radio could affect both devices. If you hear noise on
the TV or radio, do the following:
- Place the Switch as far away as possible from the TV or radio.
- Adjust the orientation of the TV or radio antenna.
- Use separate outlets.
Do not place the Switch in an undesirable environment.
 Using the switch in the following locations might shorten the life of the switch or result
in a switch malfunction.
- An area with salty air, such as the coast
- An area where corrosive gases are present, such as a hot-springs area
- An area where oily smoke is present
- An area where continuous vibrations are present
Ensure that voltage drop does not occur in the power facility due to an inrush
current.
 Turning on the Switch causes an inrush current. Ensure that voltage drop does not
occur in the power facility due to the inrush current. Voltage drops affect not only the
Switch, but also the devices connected to the same electrical power equipment.
Turn off the power before connecting or disconnecting the power cable.
 Turn off the power of the Switch before connecting or disconnecting the power cable of
an AC model, equipment for an AC (PoE) model, and an EPU model.
 Turn off the power of a power supply unit before connection or disconnection of the
power cable or the connector of the cable for a redundant power model.
 For a standby power cable, turn off the power of the power supply module first.
