Esd Prevention; Safety With Switch Moving - H3C S12500 Installation Manual

ESD prevention

CAUTION:
To prevent the electronic components from being damaged by the electrostatic discharge (ESD), you
should not only take ESD measures where the switch is located, but also take the following precautions:
Always wear an ESD-preventive wrist strap when installing components, especially the electronic printed
•
circuit boards.
• Hold a PCB by its edges. Do not touch any electronic components or printed circuit.
Check the resistance of the ESD-preventive wrist strap for safety. The resistance reading should be in the
•
range of 1 to 10 megohm (Mohm) between human body and the ground.
Perform the following steps to use the ESD-preventive wrist strap:
Wear the wrist strap on your wrist.
Step1
Lock the wrist strap tight around your wrist to keep good contact with the skin.
Step2
Insert the ESD-preventive wrist strap into the specially designed hole on the switch chassis or attach it to
Step3
the grounding screw of the chassis with the alligator clips.
Make sure that the ESD-preventive wrist strap is well grounded.

Safety with switch moving

When moving an H3C S12500 switch, perform the following steps:
Remove all the external cables (including the power cables) before moving the chassis.
•
• For personal safety, have several persons to move the switch carefully.
When moving the switch, hold the handles at both sides of the chassis. Do not hold the plastic panel
•
of the chassis, the handle of the fan tray, the handle of the back cover of the chassis, or the air vents
of chassis. Any attempt to carry the switch with these parts may cause equipment damage or even
bodily injury.
