Step 6 Insert the cable connector into the SFP module:
• For fiber-optic SFP modules, insert the LC or MT-RJ cable connector into the
SFP module.
• For copper SFP modules, insert the RJ-45 cable connector into the SFP
module.
Note When connecting to 1000BASE-T SFP modules, be sure to use a twisted
four-pair, Category 5 cable.
Removing SFP Modules from SFP Module Slots
To remove an SFP module from a module receptacle, follow these steps:
Step 1 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.
Tip For reattachment, note which cable connector plug is send (TX) and which is
receive (RX).
Step 3 For fiber-optic SFP modules, insert a dust plug into the optical ports of the SFP
module to keep the optical interfaces clean.
Step 4 Unlock and remove the SFP module, as shown in Figure 3-39.
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 index finger
to open it, use a small, flat-blade screwdriver or other long, narrow instrument to
open the bale-clasp latch.
