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 to open it, use a small, flat-blade screwdriver or other
long, narrow instrument to open the bale-clasp latch.
Step 5 Grasp the SFP module, and carefully remove it from the module slot.
Step 6 Place the removed SFP module in an antistatic bag or other protective environment.
