Removing and replacing a Fibre Channel SFP transceiver: 2145-SV1 and 2145-DH8

Edit online

When a failure occurs on a Fibre Channel link, the SFP transceiver might need to be replaced. This procedure is applicable to SAN Volume Controller 2145-SV1 and 2145-DH8 nodes.

Before you begin

The SFP transceiver is hot-plugged. You do not need to power off the SAN Volume Controller node when you replace an SFP transceiver.

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. (C030)

About this task

The following procedure is applicable to all SAN Volume Controller nodes. Complete the following steps to remove and then replace the SFP transceiver.

Procedure

  1. Carefully determine the failing physical port connection. See Fibre Channel port numbers and worldwide port names for examples of the Fibre Channel port locations.
    Important: SAN Volume Controller nodes are supported by both long-wave SFP transceivers and short-wave SFP transceivers. A long-wave 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 you are replacing a long wave SFP transceiver, ensure that you provide a suitable long wave SFP transceiver. Using the wrong type of SFP transceiver might result in loss of data access.
  2. Remove the Fibre Channel cable by pressing the release tab and pulling out the cable. Be careful to exert pressure only on the connector and do not pull on the Fibre Channel cables.
  3. Remove the SFP transceiver.
    1. Locate the release handle that is incorporated into the SFP transceiver.
    2. Unclip the handle.
    3. Use the handle to pull out the SFP transceiver.
      Note: The SFP transceivers might have a plastic tag. If so, pull the tag to remove the SFP transceiver.
  4. Push the new SFP transceiver into the aperture and ensure 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 shows an SFP transceiver and its release handle.

  5. Reconnect the Fibre Channel cable.
  6. Confirm that the error is now fixed. Check the Fibre Channel port status by using the front-panel display. If possible, check the status that is given by the SAN monitoring tools of the customer. Either mark the error as fixed or restart the node, depending on the failure indication that you originally noted.
