Fibre-Channel Sfp Transceiver - IBM Storwize V7000 Troubleshooting And Maintenance Manual

Even though many of these procedures are hot-swappable, these procedures are intended to be used only
when your system is not up and running and performing I/O operations. Unless your system is offline,
go to the management GUI and follow the fix procedures.
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. (C030)
Perform the following steps to remove and then replace the SFP transceiver:
1. Carefully determine the failing physical port connection.
Important: 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 fibre-channel 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 fibre-channel 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 23 illustrates an SFP transceiver and its release handle.

5. Reconnect the fibre-channel 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.
