NOTE:
When installing or removing an optional interface card, pay
attention to the following points:
• Avoid touching the surface-mounted components directly with
your hands.
• Avoid using excessive force in the operation.
• After removing an interface card, if no module is to be installed,
install the blank panel as soon as possible to prevent dust and
ensure the normal ventilation in the switch.
