Disconnect the cable from the SFP module. For reattachment, note which cable connector plug is send (TX) and which is receive (RX). Insert a dust plug into the optical ports of the SFP module to keep the optical interfaces clean. 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. Grasp the SFP module, and carefully remove it from the module slot. Place the removed SFP module in an antistatic bag or other protective environment.
