Safety recommendations
To avoid any equipment damage or bodily injury, read the following safety recommendations before
installation. The recommendations do not cover every possible hazardous condition.
• To avoid damage to the electrolytic capacitor in the switch, do not store the switch without power for
more than one year.
• Before cleaning the switch, remove all power cords from the switch. Do not clean the switch with a
wet cloth or liquid.
• Do not place the switch near water or in a damp environment. Prevent water or moisture from
entering the switch chassis.
1420-24G-2SFP+ 10G Uplink HNGZA-HA0022
• Do not place the switch on an unstable case or desk. The switch might be severely damaged in case
of a fall.
• Ensure good ventilation of the equipment room and keep the air inlet and outlet vents of the switch
free of obstruction.
• Make sure the operating voltage is in the required range.
• To avoid electrical shocks, do not open the chassis while the switch is operating or when the switch
is just powered off.
• The accessories shipped with the switch, including but not limited to power cables, 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."
• Lasting high relative humidity can cause poor insulation, electricity creepage, mechanical property
change of materials, and metal corrosion.
• Lasting low relative humidity can cause washer contraction and ESD and cause problems including
loose mounting screws and circuit failure.
• High temperature can accelerate the aging of insulation materials and significantly lower the
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.

Substance Concentration limit (

NOTE:
Dust diameter ≥ 5 μm
The equipment room must also meet strict limits on salts, acids, and sulfides to eliminate corrosion and
premature aging of components, as shown in Table 3.
