Page: 49 / 80

Procedure
Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis.
Step 2
Align the SFP module at the front of the slot opening.
Step 3 Insert the SFP module into the slot until the connector on the module snaps into place at the rear of the slot.
Do not remove the dust plugs from the fiber-optic SFP module port or the rubber caps from the
fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the SFP module
ports and cables from contamination and ambient light. Store the dust plugs for later use.
Caution
Step 4 Insert the appropriate cable connector into the SFP module:
• For fiber-optic SFP modules, insert the LC cable.
• For copper 1000BASE-T SFP modules, insert the RJ-45 cable.
Remove SFP Modules
Follow these steps to remove an SFP module when it is necessary.
Procedure
Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis.
Step 2 Disconnect the cable from the SFP module, and insert a dust plug into the cable end.
Step 3
Unlock and remove the SFP module.
If the module has a bale-clasp latch, pull the bale down and out to eject the module. If the bale-clasp latch is
obstructed, use a small, flat-blade screwdriver or any other narrow instrument to open the bale-clasp latch.
Step 4 Grasp the SFP module between your thumb and index finger, and carefully remove it from the module slot.
Step 5 For fiber-optic SFP modules, insert a dust plug into the optical ports of the SFP module to keep the optical
interfaces clean.
Step 6
Place the removed SFP module in an antistatic bag or other protective environment.
