Removing SFP Modules

	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.
	Step 4	If the module has a bale-clasp latch, pull the bale out and down to eject it. If the latch is obstructed and
		you cannot use your finger, use a small, flat-blade screwdriver or other long, narrow instrument.
	Step 5	Grasp the SFP module, and carefully remove it from the slot.
	Step 6	Place the module in an antistatic bag or other protective environment.
