Ensure adequate heat dissipation from the Switch by not stacking devices.
 As the AX2230S-24T, AX1250S-24T2C, and AX1240S-24T2C are fanless models,
heat also dissipates from the top panels of these switches. To ensure adequate heat
dissipation, do not stack another device on top of or below the Switch. Contact could
result in a malfunction.
When mounting these switches in a rack, keep a space of 1U or more between them.
Do not place the 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 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 near an ocean
- An area where corrosive gases are present, such as an area with hot springs
- An area where oily smoke is present
- An area where continuous vibrations are present
Do not obstruct the ventilation slots.
 Do not block the ventilation slots. Doing so causes heat to accumulate inside the
Switch, and could result in a malfunction. Maintain a space of at least 50 mm around
the ventilation slots.
Turn off the power before connecting or disconnecting the power cable.
 Turn off the power of the Switch before connecting or disconnecting the power supply
cable.
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.
