To avoid bodily injury or damage to the switch, read the following safety recommendations carefully before working with the switch. Note that the recommendations do not cover every possible hazardous condition.

·     Before cleaning the switch, remove all power cords from the switch. Do not clean the switch with 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.

·     Ensure adequate ventilation for the switch and keep the protective vent of the switch unblocked.

·     Make sure the power source voltage meets the requirements of the switch.

·     To avoid electrical shocks, do not open the chassis while the switch is operating. As a best practice, do not open the chassis even if the switch is powered off.

·     When installing the switch, always wear an ESD wrist strap. Make sure the wrist strap makes good skin contact and is reliably grounded.

 

NOTE: The switch is a class A device and might cause radio interference in a residential area. Take adequate measures as required.

 

Examining the installation environment

To ensure correct operation of your switch, make sure the installation environment meets the requirements listed in Table1-2.

Table1-2 Checking list for the installation environment

Item	Requirements
Ventilation and heat dissipation	CAUTION: To ensure correct operation of your device, make sure the installation environment is adequately ventilated to prevent the device from overheating. ·     Ensure a minimum clearance of 10 cm (3.94 in) around the chassis. ·     Do not install the device near a heat source, for example, a stove or heater. ·     Ensure air ventilation in the installation environment. ·     Do not block the ventilation holes in the device or power adapter.
Anti-moisture	CAUTION: Water or moisture might damage the circuits of the device. ·     Do not place the device near water or in a damp environment. ·     Install the switch in a clean, dry, and ventilated place where temperature is controlled in a stable range. ·     Make sure the installation environment is free from water leakage or condensation. If required, install a dehumidification device (such as an air conditioner with a dehumidification function or a dedicated dehumidifier). ·     Do not operate the device under or near the water source, such as the wash basin, laundry room, or areas with high humidity. ·     Do not touch the device with wet hands.
Lightning protection	CAUTION: Ground the switch correctly and verify the grounding. ·     If you ground the switch by using a grounding strip, make sure the grounding resistance of the grounding strip in the equipment room is less than 1Ω. ·     If you ground the switch by using a grounding conductor buried in the earth ground, make sure the grounding resistance of the grounding conductor in the ground is less than 10Ω. ·     Route the signal cables along indoor walls. If cables must be routed outdoors, bury the cables in the earth ground, or thread the cables through steel tubes. Install a signal lightning arrester with a nominal discharge current for a corresponding network interface. ·     Keep the signal cables far from power cords and lightning rod down conductors. ·     As a best practice, route power cords indoors. If an AC power cord is routed from outdoors, connect the AC power cord first to a power lightning arrester before leading it to the AC power port on the switch. Make sure the power lightning arrester has a nominal discharge current and the total length of the power cord from the power lighting arrester to the power port on the switch is less than 5 m (16.40 ft). ·     Ground the switch, rack, independent power supplies, and lightning arresters separately. ·     You must ground optical fibers with reinforcing metal stiffener from outdoors on an optical distribution frame (ODF) or fiber splice enclosure.
Cable routing	CAUTION: Do not run an Ethernet cable and power cord in parallel. ·     Route different types of cables separately. ·     Keep power cords a minimum of 5 cm (1.97 in) away from other cables.
Mechanical environment	As a best practice, make sure the mechanical class of the environment is not above 4M4 if you install the switch in an outdoor environment. NOTE: 4M represents the mechanical environment condition defined by GB/T 4798.4. It has eight classes. The 4M4 class refers to places impacted by machines, running vehicles, or ground blasting or piling.
Dust and water resistance	If you install the switch in an outdoor environment, make sure the installation and operating environments meet the requirements of IP55 rating protection. NOTE: IP indicates International Protection Rating. The first number "5" refers to the rating for preventing the solid particle from entering the cabinet. An outdoor cabinet cannot prevent dust intrusion perfectly, but the dust cannot damage the device. The second number "5" refers to the rating for preventing water from entering the cabinet. Water projected in jets against the enclosure from any direction cannot damage the device.
ESD prevention	·     Ground the switch correctly. ·     To avoid ESD damage to the device or components, always wear an ESD wrist strap when you install or remove the device. ·     Make sure the wrist strap has good skin contact and is reliably grounded.
Corrosive gas prevention	The installation site must be free from corrosive gases such as acid gases and alkaline gases.
EMI	·     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 device far away from radio transmitting stations, radar stations, and high-frequency devices. ·     Use electromagnetic shielding, for example, shielded interface cables, when necessary.

 

Checking power distribution or power supply environment

Table1-3 Requirements for power distribution or power supply environment

Item	Requirements
Preparation	The power supply must be available before you install the switch.
Voltage	The voltage provided to the switch must be within the operating voltage range. For the operating voltage range, see the hardware information and specifications for the switch.
Power receptacle and cables	·     If the external power supply system provides an AC power outlet, use a country-specific AC power cord. Make sure the PE wire of the AC power supply is grounded reliably. ·     If the external power supply system provides a DC distribution box, prepare DC power cords yourself. ·     The switch came with a terminal block connected to each power receptacle. No power cord is provided with the switch. Prepare compatible copper power wires yourself as required. For information about the wire diameter and connection requirements, see "Table2-3."

Grounding the switch with a grounding conductor buried in the earth ground

If the installation site does not have grounding strips, but earth ground is available, hammer a 2.5 m (8.20 ft) or longer angle iron or steel tube into the earth ground to act as a grounding conductor. Make sure a minimum of 0.7 m (2.30 ft) is left between the top of the grounding conductor and the ground. In cold areas, bury the grounding conductor below the frozen soil layer. In areas with thin soil or rocky gravel, determine the depth for burying the grounding conductor based on the actual condition.

If zinc-coated steel is used, the following dimension requirements must be met:

·     Angle iron—A minimum of 50 × 50 × 5 mm (1.97 × 1.97 × 0.20 in).

·     Steel tube—A minimum of 3.5 mm (0.14 in) in thickness.

·     Flat steel—A minimum of 40 × 4 mm (1.57 × 0.16 in).

·     Round steel—A minimum of 10 mm (0.39 in).

Weld the yellow-green grounding cable to the angel iron or steel tube and treat the joint for corrosion protection.
