Removing SFP, SFP+ and SFP28 Modules

Procedure
Step 1 Attach an ESD-preventive wrist strap to your wrist and to an earth ground surface.
Step 2
Disconnect the cable from the SFP/SFP+/SFP28 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/SFP+/SFP28 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 you cannot use your
finger to open the latch, use a small, flat-blade screwdriver or other long, narrow instrument to open it.
Step 5
Grasp the SFP/SFP+/SFP28 module, and carefully remove it from the slot.
Step 6 Place the SFP/SFP+/SFP28 module in an antistatic bag or other protective environment.
