Installing or Replacing an SFP

This section describes how to install or replace an SFP. SFPs can be installed in either generic interface port (ETH2 or ETH3). See Figure 11 and Figure 12 for generic interface port locations.

When replacing an SFP, make sure that you open the ejector handle completely before gently pulling it out of the interface.

Tools and Parts Required

To remove and replace an SFP, you need the following tools and parts:

• Electrostatic bag or antistatic mat, one for each SFP removed
• ESD grounding wrist strap
• Rubber safety caps to cover each unused cable and SFP

Removing an SFP

To remove an SFP:

1. Have a replacement SFP or a transceiver slot plug ready, as well as an antistatic mat and a rubber safety cap for the SFP.
2. Attach an ESD wrist strap to your bare wrist, and connect the wrist strap to an appropriate grounding point.
3. Label the cables connected to the SFP so that you can reconnect them correctly later.

   Warning: Do not look directly into a fiber-optic transceiver or into the end of a fiber-optic cable. Fiber-optic transceivers contain laser light sources that can damage your eyes.

4. Remove the cable connector plugged into the SFP.

   Caution: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

5. Pull the ejector handle out from the SFP to unlock the SFP.

   Caution: Make sure that you open the ejector handle completely (you will hear it click). This prevents damage to the SFP.

6. Grasp the SFP ejector handle, and pull the SFP approximately 0.5 in (1.3 cm) out of the interface port.
7. Using your fingers, grasp the body of the SFP, and pull it the rest of the way out.

8. Place a rubber safety cap over the transceiver.
9. Place the removed SFP on an antistatic mat or in an electrostatic bag.

Installing an SFP

To install an SFP:

1. Attach an ESD wrist strap to your bare wrist, and connect the wrist strap to an appropriate grounding point.
2. Take each SFP to be installed out of its electrostatic bag, and identify the interface where it will be installed.
3. Verify that each transceiver is covered by a rubber safety cap. If it is not, cover the transceiver with a safety cap.
4. Carefully align the SFP with the interface. The connectors should face the chassis.
5. Slide the SFP until the connector is seated in the interface. If you are unable to fully insert the SFP, make sure the connector is facing the right way.
6. Remove the rubber safety cap from the transceiver and the end of the cable. Insert the cable into the transceiver.
