For regulatory identification purposes, the switches are assigned Regulatory Model Numbers
(RMNs). The RMNs should not be confused with the marketing name HPE 1920, or the product
codes.
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.
• 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 or on a workbench, but
make sure:
• A minimum clearance of 5 cm (1.97 in) is reserved at the air inlet and exhaust vents for
ventilation.
• The rack or workbench has a good ventilation system.
• The rack or workbench is sturdy enough to support the switch and its accessories.
• The rack or workbench 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."
• Lastin
• Lasting low relative humidity can cause washer contraction and ESD and cause problems
• High temperature can accelerate the aging of insulation materials and significantly lower the

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.

Dust
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 Tab l e 3 .

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 when necessary. For example, use shielded interface cables.
