IMPORTANT:
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.
1
•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."
•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 (particles/m³) |
Dust |
≤ 3 x 104 (no visible dust on the tabletop over three days) |
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.

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.

Installing the switch
WARNING!
Before installing or moving the switch, remove the power cord.
You can install an HPE 1920 switch in a 19-inch rack, on a workbench, or on a wall.
Mounting the switch in a 19-inch rack by using mounting brackets
1.Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2.Verify that the rack is securely grounded and is stable.
3.Select mounting brackets for the switch.
{The HPE 1920 8G switch uses Type-A mounting brackets, as shown in Figure 1.
{The HPE 1920 8G PoE+ (65W) and 1920 8G PoE+ (180W) switches use Type-B mounting brackets, as shown in Figure 2.
{The HPE 1920 16G, 1920 24G, 1920 24G PoE+ (180W), 1920 24G PoE+ (370W), 1920 48G, and 1920 48G PoE+ (370W) switches use Type-C mounting brackets, as shown in Figure 3.
4.Attach the mounting brackets to both sides of the chassis with screws.
NOTE:
Mounting brackets are used only for securing the switch to the rack. A rack shelf on the rack is used to bear the switch weight.

Figure 3 Attaching Type-C mounting brackets to the switch
5.Place the switch on a rack shelf in the rack. Push the switch in until the oval holes in the brackets align with the mounting holes in the rack posts.
6.Attach the mounting brackets to the rack posts with screws.

Mounting the switch on a workbench
IMPORTANT:
•Reserve a clearance of 10 cm (3.9 in) around the chassis for heat dissipation.
•Do not place heavy objects on the switch.
To mount the switch on a workbench:
1.Verify that the workbench is sturdy and reliably grounded.
2.Place the switch bottom up, and clean the round holes in the chassis bottom with a dry cloth.
3.Attach the rubber feet to the four round holes in the chassis bottom.
4.Place the switch upside up on the workbench.
Figure 7 Attaching rubber feet (HPE 1920 24G PoE+ Switch)
Mounting the switch on a wall
Only the HPE 1920 8G switch can be installed on a wall. The type of screws used to mount the switch on the wall depends on the wall type. This section uses a concrete wall as an example.
Wall-mounting anchor kits are user supplied. The screws must be a minimum of 3 mm (0.12 in) in diameter, and the screw head must be a minimum of 6 mm (0.24 in) in diameter.
Figure 8 Wall-mounting anchor kit
To install the switch on a concrete wall:
1.Drill two holes at the same height. Make sure the spacing in between is 160 mm (6.30 in), as shown in Figure 9.
The hole depth and diameter depend on the wall anchors and screws you use. Make sure you can push the anchors to their full depth in the holes.
