Installing SFP and SFP+ Transceiver Modules
Required Tools
You will need these tools to install the SFP transceiver module:
1 Wrist strap or other personal grounding device to prevent ESD
occurrences.
2 Antistatic mat or antistatic foam to set the transceiver on.
Note: Fiber-optic end-face cleaning tools and inspection equipment. For
complete information on inspecting and cleaning fiber-optic connections, see
the white-paper document at this URL:

SFP transceiver modules can have three types of latching devices to
secure an SFP transceiver module in a port socket:
•Figure 1 shows an SFP
transceiver module with a Mylar tab latch.
•Figure 2 shows an SFP
transceiver module with an actuator button latch.
•Figure 3 shows an SFP
transceiver module that has a bail clasp latch.
•Figure 4 shows an
SFP+ transceiver module that has a bail clasp latch.
Determine which type of latch your SFP transceiver module uses before
following the installation and removal procedures.
Caution 1 Do not install or remove the SFP
transceiver module with fiber-optic cables still attached to it. Doing so may
damage cables, cable connectors, or the optical interfaces and may interfere
with the SFP transceiver module latching properly into its socket connector.
Disconnect all cables before removing or installing an SFP transceiver module.
Caution 2 The SFP transceiver modules are static
sensitive devices. Always use an ESD wrist strap or similar individual
grounding device when handling SFP transceiver modules or coming in contact
with modules.

To install an SFP
transceiver module, follow these steps:
Step 1 Attach an ESD-preventive wrist strap to
your wrist and to the ESD ground connector or a bare metal surface on your
chassis.
Step 2 Remove the SFP transceiver module from its
protective packaging.
Note Do not remove the optical bore dust plugs until directed
to do so later in the procedure.
Step 3 Check the label on the SFP transceiver
module body to verify that you have the correct model for your network.
Step 4 Find the send (TX) and receive (RX)
markings that identify the top side of the SFP transceiver module.
Note On some SFP transceiver modules, the TX and RX marking
might be replaced by arrowheads pointing from the SFP transceiver module
connector (transmit direction or TX) and toward the connector (receive
direction or RX).
Step 5 Position the SFP transceiver module in
front of the socket opening.
Note Different Cisco devices have different SFP module socket
configurations. Your Cisco device could have either a latch-up or a latch-down
orientation. Ensure that you are installing the SFP transceiver module in the
correct orientation for your Cisco device. For more details, see the hardware
installation instructions that came with your Cisco device.
Step 6 Holding it as shown in Figure 5, insert
the SFP into the socket until you feel the connector latch into place.

Transceiver Module into a Module Socket
Step 7 Press the SFP into the slot firmly with
your thumb as shown in Figure 6
Note For SFP transceiver modules equipped with an actuator
latch, you must press firmly on both the transceiver faceplate and the actuator
button to ensure that the transceiver is properly latched in the socket.
Figure 6 Latching the SFP
Step 8 To verify that the SFP is seated and
latched properly:
a. Grasp the SFP as shown in Figure 10 and try to remove it without
releasing the latch.
b. If the SFP can not be removed, it is installed and seated properly.
If the SFP can be removed, reinsert it and press harder with your thumb,
repeating if necessary until it is latched securely into the socket.

Installation
Note For optical SFP transceiver modules, before removing the
dust plugs and making any optical connections, observe the following
guidelines:
•Always keep the
protective dust plugs on the unplugged fiber-optic cable connectors and the
transceiver optical bores until you are ready to make a connection.
•Always inspect and
clean the LC connector end-faces just before making any connections. See the
Tip on this page for a pointer to a fiber-optic inspection and cleaning white
paper.
•Always grasp the LC
connector housing to plug or unplug a fiber-optic cable.
Step 9 Remove the dust plugs from the network
interface cable LC connectors. Save the dust plugs for future use.
Step 10 Inspect and clean the LC connector's
fiber-optic end-faces. See the following Tip for a pointer to a fiber-optic
inspection and cleaning white paper.

fiber-optic connections, see the white-paper document at this URL:

Step 11 Remove the dust plugs from the SFP
transceiver module optical bores.
Step 12 Immediately attach the network interface
cable LC connector to the SFP transceiver module.
Step 13 To connect 1000BASE-T SFP transceiver
modules to a copper network, follow these substeps:
Caution To comply with GR-1089 intrabuilding lightning immunity
requirements, you must use grounded, shielded, twisted-pair Category 5 cabling.
a. Insert the Category 5 network cable RJ-45 connector into the SFP
transceiver module RJ-45 connector.
Note When connecting to a
1000BASE-T-compatible server, workstation, or router, use four twisted-pair,
straight-through Category 5 cabling for the SFP transceiver module port. When
connecting to a 1000BASE-T-compatible switch or repeater, use four twisted-pair,
crossover Category 5 cabling.
b. Insert the other end of the network cable into an RJ-45 connector on
a 1000BASE-T-compatible target device.
Step 14 Observe the port status LED:
•The LED turns green
when the SFP transceiver module and the target device have an established link.
•The LED turns amber
while the STP feature discovers the network topology and searches for loops.
This process takes about 30 seconds, and then the LED turns green.
•If the LED is off,
the target device might not be turned on, there might be a cable problem, or
there might be a problem with the adapter installed in the target device. See
the Troubleshooting section of your switch hardware guide for solutions to
cabling problems.
Step 15 Reconfigure and reboot the target device
if necessary.
