Handling Static-Sensitive Devices - NEC PF5820 Installation Manual

Handling static-sensitive devices

Attention: Static electricity can damage the switch and other electronic devices.
To avoid damage, keep static-sensitive devices in their static-protective packages
until you are ready to install them.
To reduce the possibility of electrostatic discharge, observe the following
precautions:
• Limit your movement. Movement can cause static electricity to build up around
you.
• The use of a grounding system is recommended. For example, wear an
electrostatic-discharge wrist strap, if one is available.
• Handle the device carefully, holding it by its edges or its frame.
• Do not touch solder joints, pins, or exposed printed circuitry.
• Do not leave the device where others can handle and damage it.
• While the device is still in its static-protective package, touch it to an unpainted
metal part of any unpainted metal surface on a grounded rack component in the
rack in which you are installing the device, for at least 2 seconds. This drains
static electricity from the package and from your body.
• Remove the device from its package and install it directly into the switch without
setting it down. If it is necessary to set down the device, put it back into its
static-protective package. Do not place the device on a switch cover or on a
metal surface.
• Take additional care when you handle devices during cold weather. Heating
reduces indoor humidity and increases static electricity.
