    Removing a JCS1200 SFP

    Small form-factor pluggables (SFPs) are transceivers that can be removed from a fiber Gigabit Ethernet switch module. SFPs are hot-insertable and hot-removable. Removing an SFP does not interrupt switch module functioning, but the removed SFP no longer receives or transmits data.

    To remove an SFP (see Figure 1):

    1. Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the SFP. Have ready a rubber safety cap for the SFP transceiver and the cable.
    2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
    3. Label the cable connected to the SFP so that you can later reconnect it to the correct SFP.
    4. Disconnect the cable from the SFP. Immediately cover the transceiver and the end of the cable with a rubber safety cap.

      Warning: Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected to a transceiver emit laser light that can damage your eyes.

      Caution: Do not leave a fiber-optic transceiver uncovered except when you are inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.

    5. Arrange the cable in the cable management system to prevent it from dislodging or developing stress points. Secure the cable so that it is not supporting its own weight as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop in the cable management system. Placing fasteners on the loop helps to maintain its shape.

      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.

    6. Pull the ejector handle away from the SFP faceplate to unseat the SFP from the switch module. Pull the SFP out of the switch module and place it on the antistatic mat or in the electrostatic bag.

    Caution: After removing a transceiver from the chassis, wait at least 30 seconds before reinserting it or inserting a transceiver into a different slot.
