Installing SFP and SFP+ Modules
Installing an SFP or SFP+ Module
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.
• 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.
• To prevent ESD damage, follow your normal board and component handling procedures when
connecting cables to the switch and other devices.
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, either send or receive (TX or RX).
Step 3 If the module has a bale-clasp latch, move it to the open, unlocked position.
Step 4 Align the module in front of the slot opening, and push until you feel the connector snap into place.
Step 5 If the module has a bale-clasp latch, close it.
Step 6 For fiber-optic SFP or SFP+ modules, remove the dust plugs and save.
Step 7 Connect the SFP cables.
