Cooling

The gateway uses front-to-rear airflow for heat dissipation. Plan the installation site for the gateway

based on its airflow direction for adequate ventilation. Make sure the following requirements are met:

•

The installation site has a good cooling system.

•

The rack for the gateway has a good cooling system.

•

Leave a minimum clearance of 300 mm (11.81 in) around the inlet and outlet air vents.

Power

Agood power supply system is essential for correct operation of the gateway. The gateway supports

AC and DC power inputs. Make sure the equipment room meets the following requirements for the

power supply systems.

•

The AC power supply system is stable and reliable and capable of providing power required by

the gateway. Prepare a diesel generator as a backup power source except for the power lines.

•

The DC power supply system is stable and reliable and its output voltage is stable and within

the acceptable range allowed by the gateway.

•

Enough batteries are available to ensure uninterrupted device operation in the event of a power

failure.

For the power supply system to provide power as required by the router:

1. Calculate the system power consumption.

The system power consumption varies by module type and density. For more information about

system power consumption calculation, see "Appendix B Technical Specifications."

2. Select power supplies and identify the number of power supplies.

The total maximum output power of all power supplies must be higher than the system power

consumption. For more information about available power supplies, see "Appendix A FRUs and

Compatibility Matrixes."

Lightning protection

To protect the gateway from the lightning, make sure the following requirements are met:

•

The grounding cable for the chassis is correctly grounded.

•

The grounding terminal of the AC power receptacle is correctly grounded.

•

If an AC power cord is routed from outdoors for connecting to the device, connect the power

cord first to a power lightning arrester before connecting it to the power receptacle on the

device.

•

If a network cable is routed from outdoors for connecting to the device, connect the network

cable first to a network port lightning arrester before connecting it to the port.

IMPORTANT:

•

No network port lightning arrester or AC power lightning arrester is provided with the device.

Purchase them as required.

•

For the technical specifications and installation instructions for the lightning arresters, see the

documents shipped with them.

Temperature

CAUTION:

If condensation appears on the chassis when you move it to a high

-temperature environment, dry

the chassis before powering it on to avoid short circuits.

If the temperature in the equipment room is too high, too low, or changes dramatically, the device

reliability is reduced and its service lifetime is shortened.

High temperature can accelerate the aging of insulation materials and significantly lower the

reliability and lifespan of the gateway.

To ensure the correct operation of the gateway, make sure the room temperature meets the

requirements in Table 2.

Table 2 Temperature requirements

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)

Humidity

Maintain appropriate humidity in your equipment room, as described in Table 3.

•

Lasting high relative humidity tends to cause poor insulation, electricity leakage, mechanical

property change of materials, and corrosion of metal parts.

•

Lasting low relative humidity is likely to result in loose screws due to washer contraction, and

even electrostatic discharge (ESD), which causes the circuits to fail.

Table 3 Humidity requirements

Humidity Range

Operating humidity 5% RH to 95% RH, noncondensing

Humidity Range

Storage humidity 5% RH to 95% RH, noncondensing

Cleanliness

Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of

metal components and contact points. In the worst case, electrostatic adsorption can cause

communication failure.

Table 4 Dust concentration limit in the equipment room

Substance Concentration limit (particles/m3)

Dust particles ≤ 3 x 104

(No visible dust on desk in three days)

NOTE:
