• Make sure that the ground is dry and flat and anti-slip measures are in place.

• Do not place the switch in a moist area and avoid liquid surrounding the switch.

• Keep the chassis and installation tools away from walk areas.

• Do not wear loose clothing, jewelry (for example, necklace) or any other objects that could get

caught in the chassis when you install and maintain the switch.

Safety with electricity

• Clear the work area of possible hazards, such as ungrounded power extension cables, missing

safety grounds, and wet floors.

• Locate the emergency power-off switch in the room before installation. Shut the power off at once in

case any accident occurs.

• Unplug all the external cables (including power cords) before moving the chassis.

• Do not work alone when the switch has power.

• Always check that the power has been disconnected.

Safety with switch moving

To move a WX3024E switch:

• Remove all the external cables (including the power cords) before moving the chassis.

• Move the switch carefully.

ESD prevention

To prevent the electronic components from being damaged by the electrostatic discharge (ESD), take the

following precautions:

• Hold an interface card by its edges. Do not touch any electronic components or printed circuit.

• Put an interface card into an antistatic bag.

• Make sure the switch is well grounded. For how to ground the switch, see the chapter “Installing the

switch (page 14 ).

”

• Always wear an ESD-preventive wrist strap when installing components.

5

To use the ESD-preventive wrist strap:

1. Wear the wrist strap on your wrist.

2. Lock the wrist strap tight around your wrist to keep good contact with the skin.

3. Attach the wrist strap to the chassis with the alligator clips.

4. Make sure that the ESD-preventive wrist strap is well grounded.

Figure 3 Use an ESD-preventive wrist strap

NOTE:

No ESD-preventive wrist strap is provided with the switch. Prepare it by yourself.

Safety with laser

The WX3024E switch is a class 1 laser product.

WARNING!

Do not stare into any fiber port when the switch has power. The laser light emitted from

the optical fiber may hurt your eyes.

Examining the installation site

The WX3024E switch must be used indoors. To ensure normal operation and long service life of your

switch, install it in an environment that meets the requirements described in the following subsections.

Weight support

Evaluate the floor loading as compared to the actual weight of the switch and its accessories, and make

sure that the floor can support the weight of the cabinet and the switch chassis.

Temperature/humidity

Maintain appropriate temperature and humidity in the equipment room.

• Lasting high relative humidity can cause poor insulation, electricity creepage, mechanical property

change of materials, and metal corrosion.

6

• Lasting low relative humidity can cause washer contraction and ESD and bring problems including

loose captive screws and circuit failure.

• High temperature can accelerate the aging of insulation materials and significantly lower the

reliability and lifespan of the switch.

Table 4 Temperature/humidity requirements

Item Range

Operating temperature 0°C to 45°C (32°F to 113°F)

Operating humidity (noncondensing) 5% to 95%

Cleanness

Dust buildup on the chassis may 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.

Grounding

Using a good grounding system to protect your switch against lightning shocks, interferences, and ESD

is essential to the operating reliability of your switch. Make sure that the resistance between the chassis

and the ground is less than 1.5 ohm. For how to ground the switch, see the chapter “Installing the switch

(page 14 ).

”

Power supply

To satisfy the power supply requirements of the WX3024E:

7

1. Calculate the system power consumption

The total power consumption of a WX3024E depends on the number of PDs connected to it. For

more information about the system power consumption, see the chapter “Product overview

(page 3).”

2. Check that the power supply system on the installation site satisfies the power input of the power

supply modules.

Make sure the power supply system of the installation site is steady and can satisfy the input

requirements of the power supply modules such as rated voltage.

Space

For adequate ventilation and ease of maintenance, adhere to the following requirements:

• Adequate space is reserved at the air inlet and exhaust vents for heat dissipation. H3C

recommends you to reserve a space greater than 10 cm (3.94 in).

• The rack or workbench has a good ventilation system.

EMI

All electromagnetic interference (EMI) sources, from outside or inside of the switch and application

system, adversely affect the switch in a conduction pattern of capacitance coupling, inductance coupling,

electromagnetic wave radiation, or common impedance (including the grounding system) coupling. To

prevent EMI, take the following actions:

• 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.

• Route interface cables only indoors to prevent signal ports from getting damaged by over-voltage

or over-current caused by lightning strikes.

Installation tools

• Flat-blade screwdriver

• Phillips screwdriver (P2-150mm)

• ESD-preventive wrist strap

All these installation tools are user supplied.

Grounding the switch

WARNING!

Correctly connecting the switch grounding cable is crucial to lightning protection and EMI

protection.

The power input end of the switch has a noise filter, whose central ground is directly connected to the

chassis to form the chassis ground (commonly known as PGND). You must securely connect this chassis

ground to the earth so the faradism and leakage electricity can be safely released to the earth to

minimize EMI susceptibility of the switch.
