Installing SFP and SFP+ Transceiver Modules

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.

Tip For complete information on inspecting and cleaning 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.
