Cisco Catalyst 9400 Series Hardware Installation Manual page 89

Installing the Switch
When handling modules, follow these guidelines:
• Handle carriers using the available handles or edges only; avoid touching the printed circuit boards or
connectors.
• Place a removed component boardside up on an antistatic surface or in a static shielding container. If
you plan to return the component to the factory, immediately place it in a static shielding container.
• Never attempt to remove the printed circuit board from the metal carrier.
Caution
For safety, periodically check the resistance value of the antistatic strap. The measurement
should be between 1 and 10 megohm (Mohm).
