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
- Electrostatic bag or antistatic mat, one for each SFP
- ESD grounding wrist strap
- Rubber safety caps to cover each unused cable and SFP
Removing an SFP
To remove an SFP:
- Have a replacement SFP or a transceiver slot
plug ready, as well as an antistatic mat and a rubber safety cap for
- Attach an ESD wrist strap to your bare wrist, and
connect the wrist strap to an appropriate grounding point.
- Label the cables connected to the SFP so that you
can reconnect them correctly later.
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.
- Remove the cable connector plugged into the SFP.
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.
- Pull the ejector handle out from the SFP to unlock
Make sure that you open the ejector handle completely (you will
hear it click). This prevents damage to the SFP.
- Grasp the SFP ejector handle, and pull the SFP
approximately 0.5 in (1.3 cm) out of the interface port.
- Using your fingers, grasp the body of the SFP,
and pull it the rest of the way out.

- Place a rubber safety cap over the transceiver.
- Place the removed SFP on an antistatic mat or in
an electrostatic bag.
Installing an SFP
To install an SFP:
- Attach an ESD wrist strap to your bare wrist,
and connect the wrist strap to an appropriate grounding point.
- Take each SFP to be installed out of its electrostatic
bag, and identify the interface where it will be installed.
- Verify that each transceiver is covered by a rubber
safety cap. If it is not, cover the transceiver with a safety cap.
- Carefully align the SFP with the interface. The
connectors should face the chassis.
- 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.
- Remove the rubber safety cap from the transceiver
and the end of the cable. Insert the cable into the transceiver.
