Figure 3-12 Verifying the SFP Transceiver Installation

Note For an optical SFP transceiver, 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.

Tip For complete information on inspecting and cleaning fiber-optic connections, see the white-paper
