1 Put on an ESD-preventive wrist strap and ensure that the ESD-preventive
wrist strap is properly grounded.

screwdriver.
3 Hold the two sides of the OSN|M front panel with both hands and draw
back the module until the module is fully separated from the switch.

CAUTION:
Hold the two sides rather than the middle of the OSN|M front panel to
install or remove the OSN|M. Otherwise, the OSN|M may be out of
shape.
Do not apply excessive force to install or remove an OSN|M, and do
not touch the surface-mounted components directly with your hands.
After removing an OSN|M, if no new module is to be installed, install
the filler panel in time to prevent dust and ensure normal ventilation
in the switch.
