Installing and Removing SFP Modules
• For copper 1000BASE-T SFP modules, insert the RJ-45 cable connector into the SFP module.
Removing SFP Modules
To remove an SFP module from a module receptacle, follow these steps:
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 send (TX) and which is receive (RX).
Step 3 SFP module with Bale-Clasp Latch—Pull the bale out and down to eject the module as shown in
Figure 3-31. 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.
SFP module without Bale-Clasp Latch—Use the extraction tool to remove the SFP by inserting the
tool into the side of the SFP module and pulling it out of the module as shown in Figure 3-32.
