Installing and Removing SFP Modules

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 1000BASE-T 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 or

higher cable.

Removing SFP Modules

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, and insert a dust plug into the cable end.

Tip For reattachment, note which cable connector plug is send (TX) and which is receive (RX).

Step 3 Unlock and remove the SFP module, as shown in Figure 2-14.

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.

Step 4 Grasp the SFP module between your thumb and index finger, and carefully remove it from the

module slot.
