• Remove power modules, cards, and all external cables, including the power cords, before moving
the chassis.
• Cooperate with a minimum of four people to move the chassis, and use a mechanical lift as
needed.
• Lift and put down the chassis slowly and never move suddenly.
• Hold the handles on both sides of the chassis.
ESD prevention
To prevent the electric component from being damaged by electrostatic discharge (ESD), follow these
guidelines:
• Ground the switch reliably. For how to ground your switch, see "Installing the switch."
• Always wear an ESD wrist strap and make sure it is reliably grounded when installing FRUs. For
how to use an ESD wrist strap, see "Installing FRUs."
• 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 switch
has power. The laser light emitted from the fiber port might hurt your eyes.
The H3C S12500-X switches are Class 1 laser products.
Examining the installation site
The H3C S12500-X switches must be used indoors. To ensure correct operation and long lifespan of your
switch, 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, cards, power modules, and all other
components. To mount the switch in a rack, make sure the slide rails can support the total weight of the
switch and its accessories (cards, power modules, and transceiver modules).
Additionally, the floor and slide rail 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.
