Preparing for installation

Safety recommendations

Safety symbols

When reading this document, note the following symbols:

WARNING means an alert that calls attention to important information that if not understood or

followed can result in personal injury.

CAUTION means an alert that calls attention to important information that if not understood or

followed can result in data loss, data corruption, or damage to hardware or software.

General safety recommendations

•Keep the router and installation tools away from walk areas.

•Place the router in a dry and flat location and make sure anti-slip measures are in place.

•Remove all external cables and power cords before moving the router.

Electricity safety

•Locate the power-off switch in the equipment room before installation. Shut off the power

immediately if an accident occurs. Disconnect the power cord from the router if necessary.

•Make sure the router is reliably grounded.

•Do not remove and install the chassis cover when the router is operating.

•Connect the interface cables correctly.

•Use an uninterrupted power supply (UPS).

•Do not work alone when the router has power.

•Always make sure the power has been disconnected during the installation or replacement

procedure.

Examining the installation site

The router can only be used indoors. To ensure correct operation and a long lifespan for your router,

install it in an environment that meets the requirements described in the following subsections.

Temperature and humidity

Maintain the temperature and humidity in the equipment room as described in Table 1.

•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 router.

Table 1 Temperature and humidity requirements

Temperature Relative humidity

–20°C to +60°C (–4°F to +140°F) 5% to 90%, noncondensing

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 particles

≤3 x 104

(No visible dust on the tabletop in three days)

NOTE:

Dust diameter ≥5 µm

The equipment room must also meet limits on salts, acids, and sulfides to eliminate corrosion and

premature aging of components, as shown in Table 3.

Table 3 Harmful gas limits in an equipment room

Gas Maximum concentration (mg/m3)

SO20.2

H2S 0.006

NH30.05

Cl20.01

Cooling system

To ensure good ventilation, follow these guidelines:

•Maintain a minimum clearance of 10 cm (3.94 in) around the air inlet and outlet vents.

•Make sure the installation site has a good ventilation system.

ESD prevention

WARNING!

Check the resistance of the ESD wrist strap for safety. The resistance reading should be in the range

of 1 to 10 megohm (Mohm) between a human body and the ground.

To prevent electrostatic discharge (ESD), follow these guidelines:

•Make sure the router and the floor are reliably grounded.

•Take dust-proof measures for the equipment room.

•Maintain the humidity and temperature levels in the acceptable range.

•Always wear an ESD wrist strap and an ESD garment when touching a circuit board or

transceiver module.

The router does not provide an ESD wrist strap, prepare it yourself.

To attach an ESD wrist strap:

1. Wear the wrist strap on your wrist.

2. Lock the wrist strap tight around your wrist to maintain good contact with the skin.

3. Secure the wrist strap lock and the alligator clip lock together.

4. Attach the alligator clip to the grounding screw on the router.

EMI prevention

All electromagnetic interference (EMI) sources, from outside or inside of the router and application

system, adversely affect the router 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 router far away from radio transmitting stations, radar stations, and high-frequency

devices.

•Use electromagnetic shielding, for example, shielded interface cables, when necessary.

Lightning protection

To enhance lightning protection for the router, follow these guidelines:

•Make sure the router is reliably grounded.

•Make sure the AC power outlet is reliably grounded.

•Install a lightning protector at the power input end.
