Preparing for installation

Safety recommendations

To avoid any equipment damage or bodily injury caused by improper use, read the following safety recommendations before installation. Note that the recommendations do not cover every possible hazardous condition.

 Before cleaning the switch, unplug 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.

 Make sure that the ground is dry and flat and anti-slip measures are in place.  Do not place the switch on an unstable case or desk. The switch might be severely damaged in case of

a fall.

 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.

 To avoid electrical shocks, do not open the chassis while the switch is operating or when the switch is

just powered off.

Examining the installation site

The A3100 v2 Switch Series 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.

Electricity safety

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

grounds, and wet floors.

 Make sure that the operating voltage is as required.  Locate the emergency power-off switch in the room before installation. Shut the power off at once in

case accident occurs.

 Unplug all the external cables (including power cords) before moving the chassis.  Always check that the power has been disconnected.

ESD prevention

To prevent the electronic components from being damaged by the electrostatic discharge (ESD), you should not only take ESD measures where the switch is located, but also take the following precautions:

 Make sure the switch is well grounded. For how to ground the switch, see ―Grounding the switch.‖  Always wear an ESD-preventive wrist strap when installing hot swappable modules.

To use the ESD-preventive wrist strap:

(1) Rack post

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.

Temperature

Range

Operating temperature

0°C to 45°C (32°F to 113°F)

Storage temperature

–40°C to +70°C (–40°F to +158°F)

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 ESD-preventive wrist strap to a post on the rack or ground it by using other methods.

Figure 14 Use an ESD-preventive wrist strap

Laser safety

The A3100 v2 switches are Class 1 laser devices.

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.

 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 2 Temperature requirements

CAUTION:

If condensation appears on the switch when you move it to a high-temperature environment, dry the switch before powering it on to avoid short circuits.

Table 3 Humidity requirements

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 4 Dust concentration limit in the equipment room

EMI

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 5.

Table 5 Harmful gas limits in the equipment room

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.

(1) Air intake

(2) Air exhaust

 Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or

overcurrent caused by lightning strikes.

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 ground is less than 1.5 ohm. For more information about grounding the A3100 v2 Switch Series, see ―Grounding the switch.‖

Cooling

The cooling system of the A3100 v2 Switch Series varies by the switch model:

 Non PoE switches (fanless): There are openings on the left, right, and rear of the switch for natural heat

dissipation.

 PoE switches (built-in fans): Fans blow air from the left to the right of the chassis for heat dissipation. See

Figure 15.

Figure 15 Airflow through a PoE switch

For adequate heat dissipation, plan the installation site according to the airflow of your switch, and adhere to the following requirements:

 Leave a clearance of at least 10 cm (3.94 in) around the air intake and exhaust vents.  Consider the heat dissipation of the installation site when determining air-conditioning requirements to

 Make sure the hot air generated by equipment at the bottom of the rack is not drawn in the intake of the

 The installation site has a good cooling system.

Space

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

 The clearance between the rack and walls or other devices is at least 1 m (3.28 ft).  The headroom in the equipment room is no less than 3 m (9.84 ft).

ensure that cool air can enter the switch.
