Connecting the Uplink Ports
SFP and SFP+ Transceiver Modules
The SFP and SFP+ transceiver modules provide copper or fiber-optic connections to other devices. These
transceiver modules are field-replaceable and provide the uplink interfaces when installed in an SFP module
slot. The SFP modules have LC connectors for fiber-optic connections or RJ-45 connectors for copper
connections.

Installing SFP and SFP+ Transceiver Modules
Before You Begin
For cable specifications, see Appendix B, “Connector and Cable Specifications.”
Observe these precautions:
Class 1 laser product. Statement 1008Warning
•
Do not remove the dust plugs from the SFP transceiver modules or the rubber caps from the fiber-optic
cable until you are ready to connect the cable. The plugs and caps protect the module ports and cables
from contamination and ambient light.
•
Removing and installing an SFP transceiver module can shorten its useful life. Do not remove and insert
any SFP transceiver module more often than is necessary.
•
To prevent ESD damage, follow your normal board and component handling procedures when connecting
cables to the switch and other devices.
For installing SFP or SFP+ modules from the modular port card, see the Installing SFP and SFP+
Transceiver Modules in the Port Card section.
Note
Procedure
Step 1
Attach an ESD-preventive wrist strap to your wrist and to an earth ground surface.
Step 2
Find the send (Tx) and receive (Rx) markings that identify the top of the SFP module.
On some SFP transceiver modules, the send and receive (Tx and Rx) markings might be shown by arrows
that show the direction of the connection.
