Handling safety

CAUTION:

When moving the switch, hold the handles at both sides of the chassis.

Do not hold the handle of a fan tray, a power module, or the back cover of the chassis, or the air vents
of the chassis to move the switch. Any attempt to carry the switch with these parts might cause equipment

damage or even bodily injury.

To move an H3C S7500E switch:

Remove all the external cables (including the power cords) before moving the chassis.

Use a minimum of two people to move the switch, and use a mechanical lift if necessary.

Move the switch carefully.

ESD prevention

To prevent the electric component from being damaged by the electrostatic discharge (ESD), adhere to

the following requirements:

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 reliably grounded when installing pluggable
modules. 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 in an ESD bag.

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 emitted from the fiber port might hurt your eyes.

The H3C S7500E switches are class 1 laser products.

Examining the installation site

The H3C S7500E series can only be used indoors. To ensure correct operation and long service life of

your switch, the installation site must meet the requirements in this section.

Weight support

Evaluate the floor loading as compared to the actual weight of the switch and its accessories (such as

rack, chassis, cards, and power modules, and make sure the floor can support the weight of the rack and
the switch chassis.
