• 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 on the chassis.
ESD prevention
To prevent the electric component from being damaged by electrostatic discharge (ESD), follow these
guidelines:
• Ground the switch correctly. For how to ground your switch, see " Installing the switch ."
• Always wear an ESD wrist strap and make sure it is well 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 ESD bags for future use.
Laser safety
WARNING!
Do not stare into any optical port or view directly with non-attenuating optical instruments when the switch
has power. The laser light emitted from the optical fiber might hurt your eyes.
The H3C S10500 switches are Class 1 laser products.
Examining the installation site
The H3C S10500 switches must be used indoors. To make sure of the normal operation and long service
life 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 supplies, and all other
components. 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 normal operation of the switch, make sure the room temperature meets the requirements
in Table 1 .
