•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.
Table 5 Dust concentration limit in the equipment room
Substance Concentration limit (particles/cu m)
Dust particles ≤3 x 104
(No visible dust on desk in three days)
NOTE:

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.
