Removing an Interface Module
Step1 Wear an ESD-preventive wrist strap, ensure a good skin contact and make sure that the
ESD-preventive wrist strap is properly grounded.
Step2 Use a Phillips screwdriver to loosen the captive screws at both sides of the interface module until all
spring pressure is released.
Step3 Pull the interface module towards you along the guide rails, until it completely comes out of the switch
chassis.
When installing or removing an optional interface module, pay attention to the following points:
z Do not touch the surface-mounted components directly with your hands.
z Do not use too much force in the operation.
z After removing an interface module, 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.
