• The accessories shipped with the switch, including but not limited to power cords, are intended
only for the switch. Please do not use them for other products.
Examining the installation site
The switches must be used indoors. You can mount your switch in a rack, on a horizontal surface, on
a wall, or under a table. Make sure the following requirements are met:
• A minimum of 5 cm (1.97 in) of clearance is reserved at the air inlet and outlet vents for
ventilation.
• The rack has a good ventilation system and the air inlet and outlet vents are not blocked when
the switch is mounted under a table or on a horizontal surface.
• The rack, table, or horizontal surface is sturdy enough to support the switch and its accessories.
• The rack is reliably grounded.
To ensure correct operation and long service life of your switch, install it in an environment that meets
the requirements described in the following subsections.
Temperature/humidity
Maintain temperature and humidity in the equipment room as described in "Environmental
specifications."

including loose mounting screws and circuit failure.
reliability and lifespan of the switch.
Cleanliness
Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of
metal components and contact points, especially when indoor relative humidity is low. In the worst
case, electrostatic adsorption can cause communication failure.

EMI
All electromagnetic interference (EMI) sources, from outside or inside of the switch and application
system, adversely affect the switch in the following ways:
• A conduction pattern of capacitance coupling.
• Inductance coupling.
• Electromagnetic wave radiation.
• Common impedance (including the grounding system) coupling.
To prevent EMI, perform the following tasks:
• If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE)
to filter interference from the power grid.
• Keep the switch far away from radio transmitting stations, radar stations, and high-frequency
devices.
• Use electromagnetic shielding, for example, shielded interface cables, when necessary.
