Installing and Removing SFP Modules
Figure 2-13 Installing an SFP Module into an SFP Module Slot
Step 5 For fiber-optic SFP modules, remove the dust plugs from the optical ports and store them for later use.
Caution Do not remove the dust plugs from the fiber-optic SFP module port or the rubber caps from the
fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the SFP module
ports and cables from contamination and ambient light.
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 you connect to 1000BASE-T SFP modules, be sure to use a twisted four-pair, Category 5
or higher 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 2-14 .
Pull the bale-clasp latch 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.
