Safety recommendations
To avoid equipment damage or bodily injury, read the following safety recommendations before
installation. 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 good ventilation at the installation site and keep the air inlet and outlet vents of the
switch free of obstruction.
•Connect the yellow-green protection grounding cable before power-on.
•Make sure the power source voltage is as required.
•To avoid electrical shocks, do not open the chassis while the switch is operating or when the
switch is just powered off.
•To avoid ESD damage, wear an ESD wrist strap to hot-swap a power module.
Examining the installation site
The switch must be used indoors. You can mount your switch in a rack or on a workbench, but make
sure:
•Adequate clearance is reserved at the air inlet and exhaust vents for ventilation.
•The rack or workbench has a good ventilation system.
•The rack is sturdy enough to support the switch and its accessories.
•The rack or workbench 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.

2
Temperature/humidity
Maintain temperature and humidity in the equipment room as described in "Technical 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.
For the temperature and humidity requirements of different switch models, see "Appendix A Chassis
views and technical specifications."
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 x 104 (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.

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, use the following guidelines:
•If AC power is used, use a single-phase three-wire power receptacle with protective earth (PE)
to filter interference from the power grid.

3
•Keep the switch far away from radio transmitting stations, radar stations, and high-frequency
devices to make sure the EMI levels do not exceed the compliant range.
•Use electromagnetic shielding when necessary. For example, use shielded interface cables.
•To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning
strikes, only route interface cables indoors.
Laser safety
WARNING!
Disconnected optical fibers or transceiver modules might emit invisible laser light. Do not stare into
beams or view directly with optical instruments when the switch is operating.

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 to minimize the potential for system damage, maximize the safety at the
site, and minimize EMI susceptibility of the system.
You can ground the switch in one of the following ways, depending on the grounding conditions
available at the installation site:
•Grounding the switch with a grounding strip
•Grounding the switch with a grounding conductor buried in the earth ground
