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.

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.

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.
