Juniper EX4300 Series User Manual

WARNING: For safety, periodically check the resistance value of the ESD grounding
strap. The measurement must be in the range 1 through 10 Mohms.
Averssement Par mesure de sécurité, vériez régulièrement la résistance du bracelet
anstaque. Cee valeur doit être comprise entre 1 et 10 mégohms (Mohms).
• When handling any component that is subject to ESD damage and that is removed from the device,
make sure the equipment end of your ESD wrist strap is aached to the ESD point on the chassis.
If no grounding strap is available, touch the exposed, bare metal of the device to ground yourself
before handling the component.
• Avoid contact between the component that is subject to ESD damage and your clothing. ESD
voltages emied from clothing can damage components.
• When removing or installing a component that is subject to ESD damage, always place it component-
side up on an anstac surface, in an anstac card rack, or in an anstac bag (see Figure 114 on
page 385). If you are returning a component, place it in an anstac bag before packing it.
