NOTE:
•
Keep the removed filler panel properly for future use.
• When tightening the fastening screws at both sides of the interface card with a screwdriver or an electric
screwdriver, make sure the torque is not bigger than 0.4 N-m.
Removing an interface card
CAUTION:
When installing or removing an optional interface card, follow these guidelines:
• Do not touch the surface-mounted components directly with your hands.
• Do not use too much force in the operation.
• After removing an interface card, if no new module is to be installed, install the filler panel as soon as
possible to prevent dust and ensure the normal ventilation in the switch.
To remove an interface card:
1. Wear an ESD-preventive wrist strap, and make sure it makes good skin contact and is well
grounded.
2. Use a Phillips screwdriver to loosen the captive screws at both sides of the interface card until all
spring pressure is released.
3. Pull the interface card towards you along the guide rails, until it completely comes out of the switch
chassis.
