Installing an SFP or SFP+ Module
Before You Begin
When installing SFP or SFP+ modules, observe these guidelines:
•
Do not remove the dust plugs from the 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.
•
To prevent ESD damage, follow your normal board and component handling procedures when connecting
cables to the switch and other devices.
Removing and installing an SFP or SFP+ module can shorten its useful life. Do not
remove and insert any module more often than is absolutely necessary.
Caution
Procedure
Step 1
Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.
Step 2
Find the send (TX) and receive (RX) markings on the module top.
On some SFP or SFP+ modules, the send and receive (TX and RX) markings might be replaced by arrows
that show the direction of the connection.
