Installing SFP and SFP+ Modules
Installing an SFP Module
Observe these general precautions:
Warning
Class 1 laser product.
Statement 1008
• Do not remove the dust plugs from the SFP 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 module can shorten its useful life. Do not remove and insert any
SFP module more often than necessary.
• To prevent ESD damage, follow your normal board and component handling procedures when
connecting cables to the switch and other devices.
Caution To avoid damage to the network module, first install the network module in the switch before installing
the SFP modules. See the “Installing a Network Module in the Switch” section on page 2-23.
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 that identify the top side of the SFP module.
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 If the SFP 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 to lock the SFP module in place.
Step 6 Remove the SFP dust plugs and save.
Step 7 Connect the SFP cables.
