Once the module is firmly seated, secure the module to
the chassis by tightening the two captive screws. Be sure
not to overtighten the captive screws. If you use a screw-
driver, the torque used to tighten the screws must not
exceed 2.3 foot-pounds.

Install all remaining modules by repeating steps 1

instruction card included with the transceiver.
Blank Cover Plates
Blank cover plates are factory-installed in the chassis and are
used to cover empty CMM and NI slots as well as empty
power supply bays.
These cover plates play an important role in chassis airflow
and temperature management. They also provide protection for
module processor boards and other sensitive internal switch
components by closing off a chassis that is not fully populated.
Because they regulate airflow and help protect internal chassis
components, blank cover plates should remain installed at
empty module slots and power supply bays at all times.
