• Moving the chassis requires at least two people, and you can use a mechanical lift as needed.
• Lift and put down the chassis slowly and never move suddenly.
• Hold the handles of the chassis.
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 "Installing 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 "Installing the gateway."
• Hold a PCB by its edges. Do not touch any electronic components or printed circuit.
• Put cards away in ESD bags for future use.
Laser safety
WARNING!
Do not stare into or view directly with non-attenuating optical instruments any fiber port on a card 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 .
