Installing and Removing SFP Modules
Figure 2-19 SFP Module with a Bale-Clasp Latch
To insert an SFP module into the module slot, follow these steps (see Figure 2-20):
Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis.
Step 2 Find the send (TX) and receive (RX) markings that identify the top side of the SFP module.
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.
