ESD prevention
To prevent the electric component from being damaged by electrostatic discharge (ESD), follow
these guidelines:
•
Ground the gateway correctly. For how to ground your gateway, see "Grounding the gateway."
•
Always wear an ESD wrist strap and make sure it is correctly grounded when installing FRUs.
For how to use an ESD wrist strap, see "Attaching an ESD wrist strap."
•
Hold a PCB by its edges. Do not touch any electronic components or printed circuit.
•
Put cards away in antistatic bags for future use.
Laser safety
WARNING!
Do not stare into any fiber port or view directly with non-attenuating optical instruments when the
gateway is operating. The laser light emitted from the fiber port might hurt your eyes.
Examining the installation site
The gateway must be used indoors. To ensure the correct operation and long service life of your
gateway, the installation site must meet the requirements in this section.
Weight support
Make sure the floor can support the total weight of the rack, chassis, and accessories. Additionally,
the floor loading plan must also consider system expansion, such as adding more cards. For more
information, see "
Appendix A Chassis views and technical specifications
."
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.
To ensure the correct operation of the gateway, make sure the room temperature meets the
requirements in
Table 1 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
.
•
Lasting high relative humidity tends to cause poor insulation, electricity leakage, mechanical
property change of materials, and corrosion of metal parts.
