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. Store the dust plugs for later use.
Caution
Step 5
Insert the cable connector into the SFP module:
•
For fiber-optic SFP modules, insert the LC cable into the SFP module.
•
For copper 1000BASE-T SFP modules, insert the RJ-45 cable connector into the SFP module.
Removing SFP Modules
To remove an SFP module from a module receptacle, follow these steps:
SUMMARY STEPS
1.
Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis.
2.
Disconnect the cable from the SFP module, and insert a dust plug into the cable end.
3.
SFP module with Bale-Clasp Latch
—
Pull the bale out and down to eject the module as shown in the figure
below. 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.
4.
Grasp the SFP module between your thumb and index finger, and carefully remove it from the module
slot.
5.
For fiber-optic SFP modules, insert a dust plug into the optical ports of the SFP module to keep the optical
interfaces clean.
6.
Place the removed SFP module in an antistatic bag or other protective environment.
DETAILED 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.
For reattachment, note which cable connector plug is send (TX) and which is receive (RX).
