Preparing for installation
Safety recommendations
To avoid any equipment damage or bodily injury caused by incorrect use, 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. The switch might be severely damaged in
case of a fall.
•
Ensure good ventilation of the equipment room and keep the air inlet and outlet vents of the
switch free of obstruction.
•
Make sure the operating voltage is in the required range.
•
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, always wear an ESD wrist strap when replacing power modules and fan
trays.
Examining the installation site
The switch must be used indoors. Make sure the installation site meets the following requirements:
•
Adequate clearance is reserved at the air inlet and outlet vents for ventilation.
•
The rack has a good ventilation system.
•
Identify the hot aisle and cold aisle at the installation site, and make sure ambient air flows into
the switch from the cold aisle and exhausts to the hot aisle.
•
Identify the airflow designs of neighboring devices, and prevent hot air flowing out of the
neighboring devices from entering the top device.
•
The rack is sturdy enough to support the switch and its accessories.
•
The rack 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.
Temperature/humidity
Maintain appropriate temperature and humidity in the equipment room in the acceptable range. For
more information, see technical specifications in "Appendix A Chassis views and 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.

2
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 1 Dust concentration limit in the equipment room
Substance Particle diameter Concentration limit
Dust particulate ≥ 5 µm ≤ 3 × 104particles/m³
(No visible dust on the tabletop over three days)
Suspended dust ≤75 µm ≤ 0.2 mg/m3
Sedimentary dust 75 µm to 150 µm ≤ 1.5 mg/m3
Sand ≥ 150 µm ≤ 30 mg/m3
The equipment room must also meet limits on salts, acids, and sulfides to eliminate corrosion and
premature aging of components, as shown in Table 2.
Table 2 Harmful gas limits in the equipment room
Gas Maximum concentration (mg/m3)
SO20.2
H2S 0.006
NH30.05
Cl20.01
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 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.
•
To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning
strikes, route interface cables only indoors.

3
Laser safety
WARNING
!
Do not stare into any
open apertures of operating transceiver modules or optical fiber connectors.
The laser light emitted from these apertures might hurt your eyes.
The switch is a Class 1M laser device.

Grounding the switch
CAUTION:
•
Correctly connecting the grounding cable is crucial to lightning protection and EMI protection.
•
To guarantee the grounding effect, connect the switch to a grounding strip in the
equipment room
by using the grounding cable provided with the switch.

13
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 a switch by using a grounding strip at the installation site.
NOTE:
The grounding terminals in this section are for illustration only.
WARNING
!
Connect the grounding cable to the grounding system in the equipment
room. Do not connect it to a
fire main or lightning rod.
To ground the switch by using a grounding strip:
1. Attach the two-hole grounding lug of the grounding cable to a grounding point on the chassis.
For more information, see "Connecting the grounding cable to the chassis."
2. Remove the hex nut of a grounding post on the grounding strip.
