If you insert the module in slots 2 or 3, all ports are automatically configured as
M ports. With three fiber modules installed in the hub, 12 fiber MIC ports are
available.
The fiber media port module is shipped with dust plugs inserted in its
transceivers to protect the fiber-optic connectors from contamination. Keep a
dust plug in each port until you are ready to insert a fiber cable into the port.
Figure 1-7 shows how to remove a dust plug from a fiber transceiver.
