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

g high relative humidity can cause poor insulation, electricity creepage, mechanical

property change of materials, and metal corrosion.

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.

Table 2 Dust concentration limit in the equipment room

Substance Concentration limit (particles/m³)

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.
