Ventilation and heat dissipation	CAUTION: To ensure correct operation of your device, make sure the installation environment is adequately ventilated to prevent the switch 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.
Hot surface	Hot surface. Use caution when working near the hot surface. If the switch has a hot surface sign , the switch is intended for installation in a restricted access area. A restricted access area can be accessed by skilled, instructed, or qualified personnel.
Temperature/humidity	For correct operation and long service life of your switch, maintain the temperature and humidity in the equipment room at acceptable ranges. · 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. For the temperature and humidity requirements of the switch, see the hardware information and specifications for the switch.
Lightning protection	· Route the signal cables along indoor walls, 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.
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 or components. · Make sure the wrist strap has good skin contact and is reliably grounded.
Cleanliness	For more information, see "Cleanliness."
Corrosive gas prevention	The installation site must be free from corrosive gases such as acid gases and alkaline gases. For more information, see "Corrosive gas limit."
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.

Cleanliness

Dust buildup on the chassis might cause electrostatic adsorption and dust corrosion, resulting in poor contact of metal connectors and contact points. This might shorten the device's lifetime and even cause device failure in the worst case. Table1-3 describes the switch requirement for cleanliness.

Table1-3 Switch requirement for cleanliness

Substance	Particle diameter	Concentration limit
Dust particles	≥ 0.5 µm	≤ 1.8 × 107 particles/m3

To maintain cleanliness in the equipment room, follow these guidelines:

· Keep the equipment room away from pollution sources. Do not smoke, eat, or drink in the equipment room.

· Use double-layer glass in windows and seal doors and windows with dust-proof rubber strips. Use screen doors and window screens for doors and windows open to the outside and make sure the external windows are air tight.

· Use dustproof materials for floors, walls, and ceilings and use wallpaper or matt paint that does not produce powders.

· Clean the equipment room regularly and clean the air filters of the rack each month.

· Wear ESD clothing and shoe covers before entering the equipment room, keep the ESD clothing and shoe covers clean, and change them frequently.

Corrosive gas limit

Corrosive gases can accelerate corrosion and aging of metal components. Make sure the corrosive gases in the equipment room do not exceed the concentration limits as shown in Table1-4.

Figure2-6 Wall-mounting the switch (1)

Figure2-7 Wall-mounting the switch (2)

Mounting the switch on an 86 panel

Prerequisites

· Plan the networks and route the cables in advance.

· The switch models that can work alone support both local power supply (using a power adapter) and PoE power supply (using a terminal block). When you use local power supply, arrange the network cables in the 86 panel in advance. When you use PoE power supply, calculate the power consumption of the power source device and power supply distance in advance. Arrange a hybrid copper-fiber cable in the 86 panel and complete pigtail connection.

· Only the ES4200-2T1S-M supports power supply through a Type-C USB power cord. Please prepare a 1-to-2 Type-C USB power cord in advance.

· To use one switch to provide three networks, purchase an expansion bracket.

Mounting the switch on an 86 panel (single switch)

1. Press the clips on both sides of the dust cover with both hands to remove the dust cover.

Figure2-8 Removing the dust cover

2. Orient the switch so that you face the rear panel of the switch and the port side faces downwards. Gently pull down the rear cover to remove it.

Figure2-9 Removing the rear cover

3. Attach the rear cover to the 86 panel and use round-head screws to secure the rear cover.

CAUTION:

· To prevent the rear cover from damage or deformation, do not use excessive force when you attach it to the 86 panel.

· Before you attach the rear cover to the 86 panel, thread the pre-arranged hybrid copper-fiber cable or fiber in the 86 panel through the oval hole in the rear cover.

· If the distance between the round-head screw hole in the 86 box and the wall is in the range of 3 to 13 mm (0.12 to 0.51 in), add stops by using plastic studs. This prevents the round-head screws from being screwed too deeply and avoids rear cover deformation. If the distance is less than 3 mm (0.12 in), do not use plastic studs.

· As a best practice, use an electric screwdriver to fasten the round-head screws. The recommended torque is approximately 1.6 Nm (14.16 lb.in). Fasten the round-head screws until the four supports on the rear cover engage the wall and make sure the rear cover is parallel with the wall.

Figure2-10 Attaching the rear cover to the 86 panel

4. Mount the chassis. Position the pegs on the rear cover into the keyhole slots in the chassis and then slide the chassis down until the rear cover sits securely in the keyhole slots, as shown in Figure2-11 and Figure2-12.

NOTE:

· When you use PoE power supply, complete connecting the power cord and fiber before you mount the chassis. For more information, see "Connecting cables to uplink port" and "Connecting the power cord."

· Only the ES4200-4T2ST, ES4200-8T2ST, ES4200-4P2ST, ES4200-8P2ST, ES4200-8T2RS, ES4200-8P2RS, ES4200-16P2RX-B, ES4200-4P2RS, ES4200-4P2RST, ES4200-16T2RX, ES4200-16P2RS, ES4200-8T2S, and ES4200-8P2S switches support workbench mounting.

· Ensure 10 cm (3.94 in) of clearance 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 with bottom up, and clean the round holes in the chassis bottom with dry cloth.

3. (Applicable to only the ES4200-16P2RX-B and ES4200-16P2RS switches.) Attach the rubber feet to the four round holes in the chassis bottom.

4. Place the switch with upside up on the workbench.

3 Connecting cables to uplink ports

The uplink ports mentioned in this section typically connect to the uplink network, but are not exclusively used for that purpose.

To connect uplink ports, you can use common fibers, copper cables, or fibers in a hybrid copper-fiber cable. The connection method is the same for the cables. The following example connects common fibers to an uplink port on the switch.

To connect common fibers to an uplink port on the switch:

1. Install a transceiver module.

Close the bail latch upward to catch the knob on the top of the transceiver module. Grasp the transceiver module between your thumb and index finger and correctly orient it. Align it with the fiber port and push it gently into the port until you feel it snaps into place. See Figure3-2.

Transceiver modules and fiber ports have disorientation rejection designs. If you cannot insert a transceiver module easily into a port, the orientation might be wrong. Remove and reorient the transceiver module.

Figure3-2 Installing a transceiver module

2. Connect the fibers.

(Skip this step when a copper cable is used.) Grasping the fiber connector between your thumb and index finger, align it with the transceiver module optical bore and push it into the bore. Transceiver module optical bores and fiber connectors have disorientation rejection designs. If you cannot insert a fiber connector easily into a transceiver module optical bore, the orientation might be wrong. Remove and reorient the connector.

3. Coil the cable.

After you connect the fiber connectors or copper cable, fit the fibers or copper cable into the cabling channel at the chassis rear in counterclockwise direction.

4 Connecting the power cord

CAUTION:

· Provide a circuit breaker for each power cord.

· Before connecting the power cord, make sure the circuit breaker on the power cord is turned off.

Table4-1 displays the power supply methods supported by the switch.

Connecting a power adapter (local power supply)

The switch supports the following types of power adapters. The supported power adapter varies by switch model.

· Type-1 power adapter: A type-1 power adapter can meet the power supply requirements.

· Type-2 power adapter: A type-2 power adapter must be connected to an AC power cord to supply power.

To connecting a power adapter:

1. Connect the power adapter to an AC power cord. (This step is only applicable to a type-2 power adapter.)

2. Insert the circular plug of the power adapter into the power adapter receptacle on the switch.

3. Connect the other end of the power adapter to an external AC power source.

Connecting the power cord by using a terminal block (PoE power supply)

1. Remove the outer rubber sheath from the ends of the positive and negative power wires in the hybrid copper-fiber cable.

2. Use a flat-head screwdriver to press down the yellow button on the terminal block, and then insert the power wire ends into the terminal block. See Figure4-3.

3. Connect the terminal block to the PoE in port on the switch. See Figure4-4.

5 Verifying the installation

After you complete the installation, verify the following information:

· There is enough space around the switch for heat dissipation.

· The rack or workbench is stable.

· The grounding cable is connected correctly.

· The power source is as required by the switch.

· The power cords are correctly connected.

· If part of the network cable for a port is routed outdoors, verify that a network port lightning protector is used for the port. If a power line is routed from outdoors, verify that a surge protected power strip is used for the switch.
