Installing SFP Modules
Installing an SFP Module
When installing SFP modules, observe these guidelines:
• 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 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 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 SFP module in front of the slot opening, and push until you feel the connector on the module
snap into place.
Step 5 If the module has a bale-clasp latch, close it.
Step 6 For fiber-optic SFP modules, remove the SFP dust plugs and save.
Step 7 Connect the SFP cables.

Removing an SFP Module
Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.
Step 2 Disconnect the cable from the SFP module. For reattachment, note which cable connector plug is send
(TX) and which is receive (RX).
Step 3 Insert a dust plug into the optical ports of the SFP module to keep the optical interfaces clean.
Step 4 If the module has a bale-clasp latch, pull the bale out and down to eject the module. If the bale-clasp
latch is obstructed and you cannot use your finger, use a small, flat-blade screwdriver or other long,
narrow instrument to open the bale-clasp latch.
