Connecting Destination Ports
Removing and installing an SFP module can shorten its useful life. Do not remove and insert SFP
modules more often than is absolutely necessary.
Figure 2-15
SFP Module with a Bale-Clasp Latch
To insert an SFP module into the SFP module slot:
Step 1
Attach an ESD-preventive wrist strap to your wrist and to a grounded bare metal surface.
Step 2
Find the send (TX) and receive (RX) markings that identify the correct side of the SFP module.
On some SFP modules, the send and receive (TX and RX) markings might be replaced by arrows that
show the direction of the connection, either send or receive (TX or RX).
Step 3
Align the SFP module sideways in front of the slot opening.
Step 4
Insert the SFP module into the slot until you feel the connector on the module snap into place in the rear
of the slot.
Step 5
Remove the dust plugs from the SFP module optical ports and store them for later use.
Caution
Do not remove the dust plugs from the 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 LC cable connector into the SFP module.
Removing SFP Modules from SFP Module Slots
To remove an SFP module from a module receptacle:
Step 1
Attach an ESD-preventive wrist strap to your wrist and to a grounded bare metal surface.
Step 2
Disconnect the LC from the SFP module.
Step 3
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.
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. See
Figure 2-15
