Do not place a Switch in a high-temperature location.
 Do not place a 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 a Switch.
 Placing a 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.
 For the AC power, the AC (PoE) models and the EPU, turn off the Switch before
connecting or disconnecting the power cable.
 As for the redundant power model, turn off the power supply unit before connecting or
disconnecting the power cable or the cable connector.
 For a standby power cable, turn off the power of the power supply module first.
