Installing and Removing SFP Modules
Figure 3-8 Installing an SFP Module into an SFP Module Slot
Step 5 For fiber-optic SFP modules, remove the dust plugs from the optical ports, and store them for later use.
Caution 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.
Step 6 Insert the cable connector into the SFP module:
• For fiber-optic SFP modules, insert the line card or MT-RJ cable connector into the SFP module.
• For copper 1000BASE-T SFP modules, insert the RJ-45 cable connector into the SFP module.
Removing SFP Modules
Complete the following steps to remove an SFP module from a module receptacle:
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.
Tip For reattachment, note which cable connector plug is transmit (TX) and which is receive (RX).
Step 3 Unlock and remove the SFP module, as shown in Figure 3-9.
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 index finger to open it, use a small, flat-blade screwdriver
or other long, narrow instrument to open the bale-clasp latch.
