Replacing an SFP transceiver in a control enclosure

When a failure occurs on a single link, the SFP transceiver might need to be replaced.

Even though many of these 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 that you do not inadvertently disturb or remove any cables that you are not instructed to remove.

CAUTION:
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.
Perform the following steps to remove and then replace an SFP transceiver:
  1. Carefully determine the failing physical port connection.
    Important: The Fibre Channel links in the enclosures are supported with both longwave SFP transceivers and shortwave SFP transceivers. A longwave SFP transceiver has some blue components that are visible even when the SFP transceiver is plugged in. You must replace an SFP transceiver with the same type of SFP transceiver that you are replacing. If the SFP transceiver to replace is a longwave SFP transceiver, for example, you must replace with another longwave SFP transceiver. Removing the wrong SFP transceiver might result in loss of data access.
  2. Remove the optical cable by pressing the release tab and pulling the cable out. Be careful to exert pressure only on the connector and do not pull on the optical cables.
  3. Remove the SFP transceiver. There are a number of different handling or locking mechanisms that are used on the SFP transceivers. Some SFP transceivers might have a plastic tag. If so, pull the tag to remove the SFP transceiver.
    Important: Always check that the SFP transceiver that you replace matches the SFP transceiver that you remove.
  4. Push the new SFP transceiver into the aperture and ensure that it is securely pushed home. The SFP transceiver usually locks into place without having to swing the release handle until it locks flush with the SFP transceiver. Figure 1 illustrates an SFP transceiver and its release handle.

  5. Reconnect the optical cable.
  6. Confirm that the error is now fixed. Either mark the error as fixed or restart the node depending on the failure indication that you originally noted.
