Replacing an SFP transceiver

When a failure occurs on an optical link, the SFP transceiver in the port that provides the link might need to be replaced. To replace a faulty SFP transceiverwith a new one received from CRU or FRU stock, use this procedure.

Although many components are hot-swappable, they are intended to be used only when your system is not active (no I/O operations). If your system is powered on and processing I/O operations, go to the management GUI and follow the fix procedures. Initiating the replacement actions without the assistance of the fix procedures can result in loss of data or loss of access to data.

Be careful when you are replacing the hardware components that are located in the back of the system. Do not inadvertently disturb or remove any cables that you are not instructed to remove.

Some laser products contain an embedded Class 3A or Class 3B laser diode. Note the following information: laser radiation when open. Do not stare into the beam, do not view directly with optical instruments, and avoid direct exposure to the beam. (C030)
Attention: When you replace this part, you must follow recommended procedures for handling electrostatic discharge (ESD)-sensitive devices.
Complete the following steps to remove and then replace an SFP transceiver:
  1. Carefully determine the failing physical port connection.
    Important: Removing the wrong SFP transceiver might result in loss of data access.
  2. Remove the cable from the SFP.
  3. Remove the faulty SFP transceiver from its aperture.

    The SFP transceiver can vary, depending on the type of network adapter used. Figure 1 illustrates a typical SFP transceiver.

    1. Unclip the handle of the SFP transceiver.
    2. Pull on the handle of the SFP transceiver.
    3. The SFP transceiver slides out of its slot.
  4. Install the replacement SFP transceiver into the aperture that was vacated in step 3.
    1. Open the lock on the replacement SFP transceiver.
    2. Push the new SFP transceiver into the aperture until it stops.
    3. Close the release handle.
    4. Gently pull the SFP transceiver. If it is installed correctly, it does not move from its aperture.
  5. Reconnect the optical cable.
  6. Confirm that the error is now fixed. Either mark the error as fixed or restart the node, as indicated by the original failure notification.
