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.

Unlock and remove the SFP module.

If the module has a bale-clasp latch, pull the

instrument to open the bale-clasp latch.

Grasp the SFP module between your thumb and index finger, and carefully remove it from
the module slot.
