Preparing for installation

The HPE OfficeConnect 1620 Switch Series includes the models listed in Table 1.

Table 1 HPE OfficeConnect 1620 Switch Series models

Product code	HPE description		Alias	RMN
JG912A	HPE OfficeConnect 1620	8G Switch	HPE 1620 8G Switch	HNGZA-HA0017

JG913A	HPE OfficeConnect 1620	24G Switch	HPE 1620 24G Switch	HNGZA-HA0018

JG914A	HPE OfficeConnect 1620	48G Switch	HPE 1620 48G Switch	HNGZA-HA0019

IMPORTANT:

For regulatory identification purposes, the switches are assigned Regulatory Model Numbers (RMNs). The RMNs should not be confused with the marketing name HPE 1620, 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."

•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.

Table 2 Dust concentration limit in the equipment room

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.

Table 3 Harmful gas limits in the equipment room

Gas	Maximum concentration (mg/m3)
SO2	0.2

H2S	0.006
NH3	0.05
Cl2	0.01

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, use the following guidelines:

•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.

Installing the switch

WARNING!

Before installing or moving the switch, remove the power cord.

You can install an HPE 1620 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

The HPE 1620 24G and HPE 1620 48G switches have the same width. The installation procedure is the same for the switches. This section uses the HPE 1620 24G switch as an example.

To mount the switch in a 19-inch rack:

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.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 2 Attaching the mounting brackets to the HPE 1620 24G switch

4.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.

5.Attach the mounting brackets to the rack posts with screws.
