Esd Prevention; Laser Safety; Examining The Installation Site; Weight Support - H3C S12500R Series Manual

•
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 device reliably. For how to ground your device, see "Installing the device."
•
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
device has power. The laser light emitted from the fiber port might hurt your eyes.
The device is a Class 1 laser product.

Examining the installation site

The device must be used indoors. To ensure correct operation and long lifespan of your device, 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 device in a rack, make sure the slide rails can support the total
weight of the device 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 H3C S12500R Switch Router Series Hardware
Reference.

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 device, make sure the room temperature meets the requirements
in Table 1-1.
