Fiber and Cabling

1.8.2.2 Replace Faulty SFP Connectors

Small Form-factor Pluggable (SFP) connectors are hot-swappable and can be installed or removed while the card or shelf assembly is powered and running.

Warning Class I laser products. These products have been tested and comply with Class I limits.

Warning Invisible laser radiation may be emitted from the aperture ports of the single-mode fiber optic modules when no cable is connected. Avoid exposure and do not stare into open apertures.

SFPs are input/output devices that plug into a Gigabit Ethernet card to link the port with the fiber-optic network. The type of SFP determines the maximum distance that the Ethernet traffic can travel from the card to the next network device. For a description of SFPs and their capabilities, see Table 1-39 on page 1-76and refer to the Cisco ONS 15327 Reference Manual.

Note SFPs must be matched on either end by type: SX to SX, LX to LX.

Procedure: Remove SFP Connectors

Step 1 Disconnect the network fiber cable from the SFP LC duplex connector.

Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments.

Step 2 Release the SFP from the slot by simultaneously squeezing the two plastic tabs on each side.

Step 3 Slide the SFP out of the Gigabit Ethernet module slot. A flap closes over the SFP slot to protect the connector on the Gigabit Ethernet card.

Procedure: Install SFP Connectors

Step 1 Remove the SFP from its protective packaging.

Step 2 Check the label to verify that the SFP is the correct type (SX or LX) for your network.

Step 3 Verify that you are installing compatible SFPs; for example, SX to SX, LX to LX.
