Installing and Removing SFP Modules
Figure 3-18 SFP Module with a Bale-Clasp Latch
Complete the following steps to insert an SFP module into the module slot:
Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis.
Some SFP modules identify the top side of the module with transmit (TX) and receive (RX) markings
or arrows that show the direction of the connection.
Step 2 If the SFP module that you are using has the markings, use them to identify the top side of the module.
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 (see Figure 3-19).

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.
Step 6 Insert the cable connector into the SFP module:
• For fiber-optic SFP modules, insert the line card or MT-RJ cable connector into the SFP module.
• For copper 1000BASE-T SFP modules, insert the RJ-45 cable connector into the SFP module.
