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 cords, 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 leakage, 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 × 10^4 (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/m)	^3
SO_2	0.2
H_2S	0.006
NH_3	0.05
Cl_2	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, 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, for example, shielded interface cables, when necessary.

Status	Description
Steady green The switch is powered on and the power supply is operating correctly.
Flashing green	The switch is powered on and is performing the self-test. The switch is faulty if the LED flashes green for five seconds.
Off The switch is not powered on or the power supply is faulty.

Copper port LEDs

Link/ACT LEDs

Table 6 Link/ACT LED description

Status	Description
Steady yellow A 10/100-Mbps link is present.
Flashing yellow The port is receiving or sending data at 10/100 Mbps.
Steady green A 1000-Mbps link is present.
Flashing green The port is receiving or sending data at 1000 Mbps.
Off No link is present.

PoE LEDs

Table 7 PoE status LED description

Status	Description
Steady yellow The port is supplying power correctly.
Flashing yellow The port is supplying power incorrectly.
Off The port is not supplying power.

Table 8 PoE-MAX LED description(HPE 1420 5G PoE+ (32W))

Status	Description
Steady yellow The PoE power reaches the guard band (16 W to 32 W).
Off The PoE power does not reach 16 W.

Table 9 PoE-MAX LED description(HPE 1420 8G PoE+ (64W))

Status	Description
Steady yellow The PoE power reaches the guard band (48 W to 64 W).
Off The PoE power does not reach 48 W.

Table 10 PoE-MAX LED description(HPE 1420 24G PoE+ (124W))

Status	Description
Steady yellow The PoE power reaches the guard band (104 W to 124 W).
Off The PoE power does not reach 104 W.

NOTE:

A port with a smaller port ID has a higher priority for getting power. When the PoE power reaches the guard band and a new port requires power, the switch compares the port IDs and performs one of the following actions:

• Does not supply power to the new port if the ID of the new port is greater than IDs of all existing ports.
• Stops power supply to existing ports whose IDs are greater than the ID of the new port, and supplies power to the new port.
