1-2
If no mechanical lift is used, follow these guidelines to move the chassis:
•
Cooperate with a minimum of four people to move the chassis.
•
Lift the chassis by using the chassis handles or by supporting the bottom from the two sides.
•
Lift and put down the chassis slowly and never move suddenly.
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 switch is a Class 1 laser product.
Examining the installation site
The switch 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

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 correct operation of the switch, make sure the room temperature meets the requirements
