Removing SFP Modules
This section describes how to replace small-form-factor pluggable (SFP) modules. SFP modules are
inserted into the SFP modules connected to the switch.
Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.
Step 2 Disconnect the cables from the SFP module ports. For reattachment, note which cable connector plug is
send (TX) and which is receive (RX).
Note On some SFP modules, the send and receive (TX and RX) markings might be replaced by arrows
that show the direction (send or receive) of the connection.
Caution Do not remove cables from the fiber-optic SFP module ports until you are ready to insert the
dust plugs.
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.
