Installing and Removing SFP Modules
Note On some SFP modules, the send and receive (TX and RX) markings might
be replaced by arrows that show the direction of the connection, either
send or receive (TX or RX).
Step 3 Align the SFP module in front of the slot opening.
Step 4 Insert the SFP module into the slot until you feel the connector on the module snap
into place in the rear of the slot.

Step 5 For fiber-optic SFP modules, remove the dust plugs from the optical ports, and
store them for later use.
Caution Do not remove the dust plugs from the fiber-optic SFP module port or the rubber
caps from the fiber-optic cable until you are ready to connect the cable. The plugs
and caps protect the SFP module ports and cables from contamination and
ambient light.
