This service action requires you to:
|
v Turn the node off.
|
v Disconnect the power cables.
|
| v Disconnect the data cables.
Perform the following steps to remove and then replace an SFP transceiver:
|
1. Carefully determine which of the two 10 Gbps Ethernet ports is failing.
|
| 2. Read the safety information to which "Preparing to remove and replace parts" on page 26 refers.
| 3. Turn off the node while ensuring that its data is mirrored and synchronized. See MAP 5350: Powering
off a SAN Volume Controller node for more information. You power off the node because the serial
|
| cable has to be removed to give access to the SFP transceivers.
| 4. Remove the fiber-optic cable from the from the port that has the problem by pressing its release tab
and pulling the cable out. Be careful to exert pressure only on the connector and do not pull on the
|
fiber-optic cable. If necessary, remove the serial cable to get access to the SFP transceiver. If the serial
|
| cable is removed, remember to replace it.
5. Remove the SFP transceiver from the port that has the problem.
|
Locate the release handle that is incorporated into the SFP transceiver, unclip the handle, and then use
|
| the handle to pull out the SFP transceiver.
| Some SFP transceivers might have a plastic tag. If so, pull the tag to remove the SFP transceiver.
Important: The customer might be using a non-standard SFP transceiver. If so, the customer should
|
| alert you as to the SFP transceiver to use, and provide the SFP transceiver to you. Always check that
the SFP transceiver that you replace matches the SFP transceiver that you remove.
|
6. Replace the fiber-optic cable that was removed by gently pushing into the SFP until it clicks into
|
| place. Then replace the serial cable and secure it in place.
