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,
2145-DH8, 2145-CG8 or 2145-CF8 nodes.
Before you begin
The SFP transceiver is designed to be
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
- 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.
- 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.
- Remove the SFP transceiver.
- Locate the release handle that is incorporated into the SFP transceiver.
- Unclip the handle.
- 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.
- 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.

- Reconnect the Fibre Channel cable.
- 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.
